+Catch
+-----
+
+This module defines a function to help use the Catch test framework.
+
+The :command:`catch_discover_tests` discovers tests by asking the compiled test
+executable to enumerate its tests.  This does not require CMake to be re-run
+when tests change.  However, it may not work in a cross-compiling environment,
+and setting test properties is less convenient.
+
+This command is intended to replace use of :command:`add_test` to register
+tests, and will create a separate CTest test for each Catch test case.  Note
+that this is in some cases less efficient, as common set-up and tear-down logic
+cannot be shared by multiple test cases executing in the same instance.
+However, it provides more fine-grained pass/fail information to CTest, which is
+usually considered as more beneficial.  By default, the CTest test name is the
+same as the Catch name; see also ``TEST_PREFIX`` and ``TEST_SUFFIX``.
+
+.. command:: catch_discover_tests
+
+  Automatically add tests with CTest by querying the compiled test executable
+  for available tests::
+
+    catch_discover_tests(target
+                         [TEST_SPEC arg1...]
+                         [EXTRA_ARGS arg1...]
+                         [WORKING_DIRECTORY dir]
+                         [TEST_PREFIX prefix]
+                         [TEST_SUFFIX suffix]
+                         [PROPERTIES name1 value1...]
+                         [TEST_LIST var]
+    )
+
+  ``catch_discover_tests`` sets up a post-build command on the test executable
+  that generates the list of tests by parsing the output from running the test
+  with the ``--list-test-names-only`` argument.  This ensures that the full
+  list of tests is obtained.  Since test discovery occurs at build time, it is
+  not necessary to re-run CMake when the list of tests changes.
+  However, it requires that :prop_tgt:`CROSSCOMPILING_EMULATOR` is properly set
+  in order to function in a cross-compiling environment.
+
+  Additionally, setting properties on tests is somewhat less convenient, since
+  the tests are not available at CMake time.  Additional test properties may be
+  assigned to the set of tests as a whole using the ``PROPERTIES`` option.  If
+  more fine-grained test control is needed, custom content may be provided
+  through an external CTest script using the :prop_dir:`TEST_INCLUDE_FILES`
+  directory property.  The set of discovered tests is made accessible to such a
+  script via the ``<target>_TESTS`` variable.
+
+  The options are:
+
+  ``target``
+    Specifies the Catch executable, which must be a known CMake executable
+    target.  CMake will substitute the location of the built executable when
+    running the test.
+
+  ``TEST_SPEC arg1...``
+    Specifies test cases, wildcarded test cases, tags and tag expressions to
+    pass to the Catch executable with the ``--list-test-names-only`` argument.
+
+  ``EXTRA_ARGS arg1...``
+    Any extra arguments to pass on the command line to each test case.
+
+  ``WORKING_DIRECTORY dir``
+    Specifies the directory in which to run the discovered test cases.  If this
+    option is not provided, the current binary directory is used.
+
+  ``TEST_PREFIX prefix``
+    Specifies a ``prefix`` to be prepended to the name of each discovered test
+    case.  This can be useful when the same test executable is being used in
+    multiple calls to ``catch_discover_tests()`` but with different
+    ``TEST_SPEC`` or ``EXTRA_ARGS``.
+
+  ``TEST_SUFFIX suffix``
+    Similar to ``TEST_PREFIX`` except the ``suffix`` is appended to the name of
+    every discovered test case.  Both ``TEST_PREFIX`` and ``TEST_SUFFIX`` may
+    be specified.
+
+  ``PROPERTIES name1 value1...``
+    Specifies additional properties to be set on all tests discovered by this
+    invocation of ``catch_discover_tests``.
+
+  ``TEST_LIST var``
+    Make the list of tests available in the variable ``var``, rather than the
+    default ``<target>_TESTS``.  This can be useful when the same test
+    executable is being used in multiple calls to ``catch_discover_tests()``.
+    Note that this variable is only available in CTest.

-* __margin__ - margin serves to set the the absolute value by which a result can be erroneous before it is rejected. By default set to `0.0`.
-* __scale__ - scale serves to adjust the epsilon's multiplicator. By default set to `0.0`.
+`Approx` is constructed with defaults that should cover most simple cases.

 ```cpp
 Approx target = Approx(100).epsilon(0.01);
 100.0 == target; // Obviously true

 Currently assertions in Catch are not thread safe.
 For more details, along with workarounds, see the section on [the limitations page](limitations.md#thread-safe-assertions).
 
+## Expressions with commas
+
+Because the preprocessor parses code using different rules than the
+compiler, multiple-argument assertions (e.g. `REQUIRE_THROWS_AS`) have
+problems with commas inside the provided expressions. As an example
+`REQUIRE_THROWS_AS(std::pair<int, int>(1, 2), std::invalid_argument);`
+will fail to compile, because the preprocessor sees 3 arguments provided,

+1) Use typedef:
+```cpp
+using int_pair = std::pair<int, int>;
+REQUIRE_THROWS_AS(int_pair(1, 2), std::invalid_argument);

 The disadvantage is that this schema was designed to correspond to how JUnit works - and there is a significant mismatch with how Catch works. Additionally the format is not streamable (because opening elements hold counts of failed and passing tests as attributes) - so the whole test run must complete before it can be written.
 
 ## Other reporters
-Other reporters are not part of the single-header distribution and need to be downloaded and included separately. All reporters are stored in `include/reporters` directory in the git repository, and are named `catch_reporter_*.hpp`.

-### CMake
-
-In general we recommend "vendoring" Catch's single-include releases inside your own repository. If you do this, the following example shows a minimal CMake project:
-```CMake
-cmake_minimum_required(VERSION 3.0)
-
-project(cmake_test)
-
-# Prepare "Catch" library for other executables
-set(CATCH_INCLUDE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/catch)
-add_library(Catch INTERFACE)
-target_include_directories(Catch INTERFACE ${CATCH_INCLUDE_DIR})
-
-# Make test executable
-set(TEST_SOURCES ${CMAKE_CURRENT_SOURCE_DIR}/main.cpp)
-add_executable(tests ${TEST_SOURCES})
-target_link_libraries(tests Catch)
-```
-Note that it assumes that the path to the Catch's header is `catch/catch.hpp` from the `CMakeLists.txt` file.
-
-
-You can also use the following CMake snippet to automatically fetch the entire Catch repository from github and configure it as an external project:
-```CMake
-cmake_minimum_required(VERSION 2.8.8)
-project(catch_builder CXX)
-include(ExternalProject)
-find_package(Git REQUIRED)
-
-ExternalProject_Add(
-    catch
-    PREFIX ${CMAKE_BINARY_DIR}/catch
-    GIT_REPOSITORY https://github.com/philsquared/Catch.git
-    TIMEOUT 10
-    UPDATE_COMMAND ${GIT_EXECUTABLE} pull
-    CONFIGURE_COMMAND ""
-    BUILD_COMMAND ""
-    INSTALL_COMMAND ""
-    LOG_DOWNLOAD ON
-   )
-
-# Expose required variable (CATCH_INCLUDE_DIR) to parent scope
-ExternalProject_Get_Property(catch source_dir)
-set(CATCH_INCLUDE_DIR ${source_dir}/single_include CACHE INTERNAL "Path to include folder for Catch")
-```
-
-If you put it in, e.g., `${PROJECT_SRC_DIR}/${EXT_PROJECTS_DIR}/catch/`, you can use it in your project by adding the following to your root CMake file:
-
-```CMake
-# Includes Catch in the project:
-add_subdirectory(${EXT_PROJECTS_DIR}/catch)
-include_directories(${CATCH_INCLUDE_DIR} ${COMMON_INCLUDES})
-enable_testing(true)  # Enables unit-testing.
-```
-
-The advantage of this approach is that you can always automatically update Catch to the latest release. The disadvantage is that it means bringing in lot more than you need.
-
-
-### Automatic test registration
-If you are also using ctest, `contrib/ParseAndAddCatchTests.cmake` is a CMake script that attempts to parse your test files and automatically register all test cases, using tags as labels. This means that these
-```cpp
-TEST_CASE("Test1", "[unit]") {
-    int a = 1;
-    int b = 2;
-    REQUIRE(a == b);
-}
-
-TEST_CASE("Test2") {
-    int a = 1;
-    int b = 2;
-    REQUIRE(a == b);
-}
-
-TEST_CASE("Test3", "[a][b][c]") {
-    int a = 1;
-    int b = 2;
-    REQUIRE(a == b);
-}
-```
-would be registered as 3 tests, `Test1`, `Test2` and `Test3`, and 4 ctest labels would be created, `a`, `b`, `c` and `unit`.
-
 ### CodeCoverage module (GCOV, LCOV...)
 
 If you are using GCOV tool to get testing coverage of your code, and are not sure how to integrate it with CMake and Catch, there should be an external example over at https://github.com/fkromer/catch_cmake_coverage
 
+
+### pkg-config
+
+Catch2 provides a rudimentary pkg-config integration, by registering itself
+under the name `catch2`. This means that after Catch2 is installed, you
+can use `pkg-config` to get its include path: `pkg-config --cflags catch2`.
+
+### gdb and lldb scripts
+
+Catch2's `contrib` folder also contains two simple debugger scripts,
+`gdbinit` for `gdb` and `lldbinit` for `lldb`. If loaded into their
+respective debugger, these will tell it to step over Catch2's internals
+when stepping through code.

+[Automatic test registration](#automatic-test-registration)<br>
+[CMake project options](#cmake-project-options)<br>
+[Installing Catch2 from git repository](#installing-catch2-from-git-repository)<br>
+
+Because we use CMake to build Catch2, we also provide a couple of
+integration points for our users.
+
+1) Catch2 exports a (namespaced) CMake target
+2) Catch2's repository contains CMake scripts for automatic registration
+of `TEST_CASE`s in CTest
+
+## CMake target
+
+Catch2's CMake build exports an interface target `Catch2::Catch2`. Linking
+against it will add the proper include path and all necessary capabilities
+to the resulting binary.
+
+This means that if Catch2 has been installed on the system, it should be
+enough to do:
+```cmake
+find_package(Catch2 REQUIRED)
+target_link_libraries(tests Catch2::Catch2)
+```
+
+
+This target is also provided when Catch2 is used as a subdirectory.
+Assuming that Catch2 has been cloned to `lib/Catch2`:
+```cmake
+add_subdirectory(lib/Catch2)
+target_link_libraries(tests Catch2::Catch2)
+```
+
+## Automatic test registration
+
+Catch2's repository also contains two CMake scripts that help users
+with automatically registering their `TEST_CASE`s with CTest. They
+can be found in the `contrib` folder, and are
+
+1) `Catch.cmake` (and its dependency `CatchAddTests.cmake`)
+2) `ParseAndAddCatchTests.cmake`
+
+If Catch2 has been installed in system, both of these can be used after
+doing `find_package(Catch2 REQUIRED)`. Otherwise you need to add them
+to your CMake module path.
+
+### `Catch.cmake` and `AddCatchTests.cmake`
+
+`Catch.cmake` provides function `catch_discover_tests` to get tests from
+a target. This function works by running the resulting executable with
+`--list-test-names-only` flag, and then parsing the output to find all
+existing tests.
+
+#### Usage
+```cmake
+cmake_minimum_required(VERSION 3.5)
+
+project(baz LANGUAGES CXX VERSION 0.0.1)
+
+find_package(Catch2 REQUIRED)
+add_executable(foo test.cpp)
+target_link_libraries(foo Catch2::Catch2)
+
+include(CTest)
+include(Catch)
+catch_discover_tests(foo)
+```
+
+
+#### Customization
+`catch_discover_tests` can be given several extra argumets:
+```cmake
+catch_discover_tests(target
+                     [TEST_SPEC arg1...]
+                     [EXTRA_ARGS arg1...]
+                     [WORKING_DIRECTORY dir]
+                     [TEST_PREFIX prefix]
+                     [TEST_SUFFIX suffix]
+                     [PROPERTIES name1 value1...]
+                     [TEST_LIST var]
+)
+```
+
+* `TEST_SPEC arg1...`
+
+Specifies test cases, wildcarded test cases, tags and tag expressions to
+pass to the Catch executable alongside the `--list-test-names-only` flag.
+
+
+* `EXTRA_ARGS arg1...`
+
+Any extra arguments to pass on the command line to each test case.
+
+
+* `WORKING_DIRECTORY dir`
+
+Specifies the directory in which to run the discovered test cases.  If this
+option is not provided, the current binary directory is used.
+
+
+* `TEST_PREFIX prefix`
+
+Specifies a _prefix_ to be added to the name of each discovered test case.
+This can be useful when the same test executable is being used in multiple
+calls to `catch_discover_tests()`, with different `TEST_SPEC` or `EXTRA_ARGS`.
+
+
+* `TEST_SUFFIX suffix`
+
+Same as `TEST_PREFIX`, except it specific the _suffix_ for the test names.
+Both `TEST_PREFIX` and `TEST_SUFFIX` can be specified at the same time.
+
+
+* `PROPERTIES name1 value1...`
+
+Specifies additional properties to be set on all tests discovered by this
+invocation of `catch_discover_tests`.
+
+
+* `TEST_LIST var`
+
+Make the list of tests available in the variable `var`, rather than the
+default `<target>_TESTS`.  This can be useful when the same test
+executable is being used in multiple calls to `catch_discover_tests()`.
+Note that this variable is only available in CTest.
+
+
+### `ParseAndAddCatchTests.cmake`
+
+`ParseAndAddCatchTests` works by parsing all implementation files
+associated with the provided target, and registering them via CTest's
+`add_test`. This approach has some limitations, such as the fact that
+commented-out tests will be registered anyway.
+
+
+#### Usage
+
+```cmake
+cmake_minimum_required(VERSION 3.5)
+
+project(baz LANGUAGES CXX VERSION 0.0.1)
+
+find_package(Catch2 REQUIRED)
+add_executable(foo test.cpp)
+target_link_libraries(foo Catch2::Catch2)
+
+include(CTest)
+include(ParseAndAddCatchTests)
+ParseAndAddCatchTests(foo)
+```
+
+
+#### Customization
+
+`ParseAndAddCatchTests` provides some customization points:
+* `PARSE_CATCH_TESTS_VERBOSE` -- When `ON`, the script prints debug
+messages. Defaults to `OFF`.
+* `PARSE_CATCH_TESTS_NO_HIDDEN_TESTS` -- When `ON`, hidden tests (tests
+tagged with any of `[!hide]`, `[.]` or `[.foo]`) will not be registered.
+Defaults to `OFF`.
+* `PARSE_CATCH_TESTS_ADD_FIXTURE_IN_TEST_NAME` -- When `ON`, adds fixture
+class name to the test name in CTest. Defaults to `ON`.
+* `PARSE_CATCH_TESTS_ADD_TARGET_IN_TEST_NAME` -- When `ON`, adds target
+name to the test name in CTest. Defaults to `ON`.
+* `PARSE_CATCH_TESTS_ADD_TO_CONFIGURE_DEPENDS` -- When `ON`, adds test
+file to `CMAKE_CONFIGURE_DEPENDS`. This means that the CMake configuration
+step will be re-ran when the test files change, letting new tests be
+automatically discovered. Defaults to `OFF`.
+
+
+Optionally, one can specify a launching command to run tests by setting the
+variable `OptionalCatchTestLauncher` before calling `ParseAndAddCatchTests`. For
+instance to run some tests using `MPI` and other sequentially, one can write
+```cmake
+set(OptionalCatchTestLauncher ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} ${NUMPROC})
+ParseAndAddCatchTests(mpi_foo)
+unset(OptionalCatchTestLauncher)
+ParseAndAddCatchTests(bar)
+```
+
+## CMake project options
+
+Catch2's CMake project also provides some options for other projects
+that consume it. These are
+
+* `CATCH_BUILD_TESTING` -- When `ON`, Catch2's SelfTest project will be
+built. Defaults to `ON`. Note that Catch2 also obeys `BUILD_TESTING` CMake
+variable, so _both_ of them need to be `ON` for the SelfTest to be built,
+and either of them can be set to `OFF` to disable building SelfTest.
+* `CATCH_BUILD_EXAMPLES` -- When `ON`, Catch2's usage examples will be
+built. Defaults to `OFF`.
+* `CATCH_INSTALL_DOCS` -- When `ON`, Catch2's documentation will be
+included in the installation. Defaults to `ON`.
+* `CATCH_INSTALL_HELPERS` -- When `ON`, Catch2's contrib folder will be
+included in the installation. Defaults to `ON`.
+* `BUILD_TESTING` -- When `ON` and the project is not used as a subproject,
+Catch2's test binary will be built. Defaults to `ON`.
+
+
+## Installing Catch2 from git repository
+
+If you cannot install Catch2 from a package manager (e.g. Ubuntu 16.04
+provides catch only in version 1.2.0) you might want to install it from
+the repository instead. Assuming you have enough rights, you can just
+install it to the default location, like so:
+```
+$ git clone https://github.com/catchorg/Catch2.git
+$ cd Catch2
+$ cmake -Bbuild -H. -DBUILD_TESTING=OFF
+$ sudo cmake --build build/ --target install
+```
+
+If you do not have superuser rights, you will also need to specify
+[CMAKE_INSTALL_PREFIX](https://cmake.org/cmake/help/latest/variable/CMAKE_INSTALL_PREFIX.html)
+when configuring the build, and then modify your calls to
+[find_package](https://cmake.org/cmake/help/latest/command/find_package.html)
+accordingly.

 Catch formats output intended for the console to fit within a fixed number of characters. This is especially important as indentation is used extensively and uncontrolled line wraps break this.

     std::ostream& cout();

     std::ostream& clog();
 
-This can be useful on certain platforms that do not provide the standard iostreams, such as certain embedded systems.
+[You can see an example of replacing these functions here.](
+../examples/231-Cfg-OutputStreams.cpp)
 
 
+## Fallback stringifier
+
+By default, when Catch's stringification machinery has to stringify
+a type that does not specialize `StringMaker`, does not overload `operator<<`,
+is not an enumeration and is not a range, it uses `"{?}"`. This can be
+overriden by defining `CATCH_CONFIG_FALLBACK_STRINGIFIER` to name of a
+function that should perform the stringification instead.
+
+All types that do not provide `StringMaker` specialization or `operator<<`
+overload will be sent to this function (this includes enums and ranges).
+The provided function must return `std::string` and must accept any type,
+e.g. via overloading.
+
+_Note that if the provided function does not handle a type and this type
+requires to be stringified, the compilation will fail._
+
+
+## Default reporter
+
+Catch's default reporter can be changed by defining macro
+`CATCH_CONFIG_DEFAULT_REPORTER` to string literal naming the desired
+default reporter.
+
+This means that defining `CATCH_CONFIG_DEFAULT_REPORTER` to `"console"`
+is equivalent with the out-of-the-box experience.
+
+
+## C++11 toggles
+
+    CATCH_CONFIG_CPP11_TO_STRING // Use `std::to_string`
+
+Because we support platforms whose standard library does not contain
+`std::to_string`, it is possible to force Catch to use a workaround
+based on `std::stringstream`. On platforms other than Android,
+the default is to use `std::to_string`. On Android, the default is to
+use the `stringstream` workaround. As always, it is possible to override
+Catch's selection, by defining either `CATCH_CONFIG_CPP11_TO_STRING` or
+`CATCH_CONFIG_NO_CPP11_TO_STRING`.
+
+
+## C++17 toggles
+
+    CATCH_CONFIG_CPP17_UNCAUGHT_EXCEPTIONS  // Use std::uncaught_exceptions instead of std::uncaught_exception
+    CATCH_CONFIG_CPP17_STRING_VIEW          // Provide StringMaker specialization for std::string_view
+    CATCH_CONFIG_CPP17_VARIANT              // Override C++17 detection for CATCH_CONFIG_ENABLE_VARIANT_STRINGMAKER
+
+Catch contains basic compiler/standard detection and attempts to use
+some C++17 features whenever appropriate. This automatic detection
+can be manually overridden in both directions, that is, a feature
+can be enabled by defining the macro in the table above, and disabled
+by using `_NO_` in the macro, e.g. `CATCH_CONFIG_NO_CPP17_UNCAUGHT_EXCEPTIONS`.

+_Generators are currently considered an experimental feature and their
+API can change between versions freely._
+
+Data generators (also known as _data driven/parametrized test cases_)
+let you reuse the same set of assertions across different input values.
+In Catch2, this means that they respect the ordering and nesting
+of the `TEST_CASE` and `SECTION` macros.
+
+How does combining generators and test cases work might be better
+explained by an example:
+
+```cpp
+TEST_CASE("Generators") {
+    auto i = GENERATE( range(1, 11) );
+
+    SECTION( "Some section" ) {
+        auto j = GENERATE( range( 11, 21 ) );
+        REQUIRE(i < j);
+    }
+}
+```
+
+the assertion will be checked 100 times, because there are 10 possible
+values for `i` (1, 2, ..., 10) and for each of them, there are 10 possible
+values for `j` (11, 12, ..., 20).
+
+You can also combine multiple generators by concatenation:
+```cpp
+static int square(int x) { return x * x; }
+TEST_CASE("Generators 2") {
+    auto i = GENERATE(0, 1, -1, range(-20, -10), range(10, 20));
+    CAPTURE(i);
+    REQUIRE(square(i) >= 0);
+}
+```
+
+This will call `square` with arguments `0`, `1`, `-1`, `-20`, ..., `-11`,
+`10`, ..., `19`.
+
+----------
+
+Because of the experimental nature of the current Generator implementation,
+we won't list all of the first-party generators in Catch2. Instead you
+should look at our current usage tests in
+[projects/SelfTest/UsageTests/Generators.tests.cpp](/projects/SelfTest/UsageTests/Generators.tests.cpp).

+Catch also aims to provide a set of generic matchers. Currently this set

+
+Because of type inference limitations, the argument type of the predicate

+# Other macros
+
+This page serves as a reference for macros that are not documented
+elsewhere. For now, these macros are separated into 2 rough categories,
+"assertion related macros" and "test case related macros".
+
+## Assertion related macros
+
+* `CHECKED_IF` and `CHECKED_ELSE`
+
+`CHECKED_IF( expr )` is an `if` replacement, that also applies Catch2's
+stringification machinery to the _expr_ and records the result. As with
+`if`, the block after a `CHECKED_IF` is entered only if the expression
+evaluates to `true`. `CHECKED_ELSE( expr )` work similarly, but the block
+is entered only if the _expr_ evaluated to `false`.
+
+Example:
+```cpp
+int a = ...;
+int b = ...;
+CHECKED_IF( a == b ) {
+    // This block is entered when a == b
+} CHECKED_ELSE ( a == b ) {
+    // This block is entered when a != b
+}
+```
+
+* `CHECK_NOFAIL`
+
+`CHECK_NOFAIL( expr )` is a variant of `CHECK` that does not fail the test
+case if _expr_ evaluates to `false`. This can be useful for checking some
+assumption, that might be violated without the test neccessarily failing.
+
+Example output:
+```
+main.cpp:6:
+FAILED - but was ok:
+  CHECK_NOFAIL( 1 == 2 )
+
+main.cpp:7:
+PASSED:
+  CHECK( 2 == 2 )
+```
+
+* `SUCCEED`
+
+`SUCCEED( msg )` is mostly equivalent with `INFO( msg ); REQUIRE( true );`.
+In other words, `SUCCEED` is for cases where just reaching a certain line
+means that the test has been a success.
+
+Example usage:
+```cpp
+TEST_CASE( "SUCCEED showcase" ) {
+    int I = 1;
+    SUCCEED( "I is " << I );
+}
+```
+
+* `STATIC_REQUIRE`
+
+`STATIC_REQUIRE( expr )` is a macro that can be used the same way as a
+`static_assert`, but also registers the success with Catch2, so it is
+reported as a success at runtime. The whole check can also be deferred
+to the runtime, by defining `CATCH_CONFIG_RUNTIME_STATIC_REQUIRE` before
+including the Catch2 header.
+
+Example:
+```cpp
+TEST_CASE("STATIC_REQUIRE showcase", "[traits]") {
+    STATIC_REQUIRE( std::is_void<void>::value );
+    STATIC_REQUIRE_FALSE( std::is_void<int>::value );
+}
+```
+
+## Test case related macros
+
+* `METHOD_AS_TEST_CASE`
+
+`METHOD_AS_TEST_CASE( member-function-pointer, description )` lets you
+register a member function of a class as a Catch2 test case. The class
+will be separately instantiated for each method registered in this way.
+
+```cpp
+class TestClass {
+    std::string s;
+
+public:
+    TestClass()
+        :s( "hello" )
+    {}
+
+    void testCase() {
+        REQUIRE( s == "hello" );
+    }
+};
+
+
+METHOD_AS_TEST_CASE( TestClass::testCase, "Use class's method as a test case", "[class]" )
+```
+
+* `REGISTER_TEST_CASE`
+
+`REGISTER_TEST_CASE( function, description )` let's you register
+a `function` as a test case. The function has to have `void()` signature,
+the description can contain both name and tags.
+
+Example:
+```cpp
+REGISTER_TEST_CASE( someFunction, "ManuallyRegistered", "[tags]" );
+```
+
+_Note that the registration still has to happen before Catch2's session
+is initiated. This means that it either needs to be done in a global
+constructor, or before Catch2's session is created in user's own main._
+
+
+* `ANON_TEST_CASE`
+
+`ANON_TEST_CASE` is a `TEST_CASE` replacement that will autogenerate
+unique name. The advantage of this is that you do not have to think
+of a name for the test case,`the disadvantage is that the name doesn't
+neccessarily remain stable across different links, and thus it might be
+hard to run directly.
+
+Example:
+```cpp
+ANON_TEST_CASE() {
+    SUCCEED("Hello from anonymous test case");
+}
+```
+
+* `DYNAMIC_SECTION`
+
+`DYNAMIC_SECTION` is a `SECTION` where the user can use `operator<<` to
+create the final name for that section. This can be useful with e.g.
+generators, or when creating a `SECTION` dynamically, within a loop.
+
+Example:
+```cpp
+TEST_CASE( "looped SECTION tests" ) {
+    int a = 1;
+
+    for( int b = 0; b < 10; ++b ) {
+        DYNAMIC_SECTION( "b is currently: " << b ) {
+            CHECK( b > a );
+        }
+    }
+}
+```

+## Version detection
+
+Catch provides a triplet of macros providing the header's version, 
+
+* `CATCH_VERSION_MAJOR`
+* `CATCH_VERSION_MINOR`
+* `CATCH_VERSION_PATCH`
+
+these macros expand into a single number, that corresponds to the appropriate
+part of the version. As an example, given single header version v2.3.4,
+the macros would expand into `2`, `3`, and `4` respectively.

-## Improvements
+
+## 2.4.2
+
+### Improvements
+* XmlReporter now also outputs the RNG seed that was used in a run (#1404)
+* `Catch::Session::applyCommandLine` now also accepts `wchar_t` arguments.
+  * However, Catch2 still does not support unicode.
+* Added `STATIC_REQUIRE` macro (#1356, #1362)
+* Catch2's singleton's are now cleaned up even if tests are run (#1411)
+  * This is mostly useful as a FP prevention for users who define their own main.
+* Specifying an invalid reporter via `-r` is now reported sooner (#1351, #1422)
+
+
+### Fixes
+* Stringification no longer assumes that `char` is signed (#1399, #1407)
+  * This caused a `Wtautological-compare` warning.
+* SFINAE for `operator<<` no longer sees different overload set than the actual insertion (#1403)
+
+
+### Contrib
+* `catch_discover_tests` correctly adds tests with comma in name (#1327, #1409)
+* Added a new customization point in how the tests are launched to `catch_discover_tests`
+
+
+## 2.4.1
+
+### Improvements
+* Added a StringMaker for `std::(w)string_view` (#1375, #1376)
+* Added a StringMaker for `std::variant` (#1380)
+  * This one is disabled by default to avoid increased compile-time drag
+* Added detection for cygwin environment without `std::to_string` (#1396, #1397)
+
+### Fixes
+* `UnorderedEqualsMatcher` will no longer accept erroneously accept
+vectors that share suffix, but are not permutation of the desired vector
+* Abort after (`-x N`) can no longer be overshot by nested `REQUIRES` and
+subsequently ignored (#1391, #1392)
+
+
+## 2.4.0
+
+**This release brings two new experimental features, generator support
+and a `-fno-exceptions` support. Being experimental means that they
+will not be subject to the usual stability guarantees provided by semver.**
+
+### Improvements
+* Various small runtime performance improvements
+* `CAPTURE` macro is now variadic
+* Added `AND_GIVEN` macro (#1360)
+* Added experimental support for data generators
+  * See [their documentation](generators.md) for details
+* Added support for compiling and running Catch without exceptions
+  * Doing so limits the functionality somewhat
+  * Look [into the documentation](configuration.md#disablingexceptions) for details
+
+### Fixes
+* Suppressed `-Wnon-virtual-dtor` warnings in Matchers (#1357)
+* Suppressed `-Wunreachable-code` warnings in floating point matchers (#1350)
+
+### CMake
+* It is now possible to override which Python is used to run Catch's tests (#1365)
+* Catch now provides infrastructure for adding tests that check compile-time configuration
+* Catch no longer tries to install itself when used as a subproject (#1373)
+* Catch2ConfigVersion.cmake is now generated as arch-independent (#1368)
+  * This means that installing Catch from 32-bit machine and copying it to 64-bit one works
+  * This fixes conan installation of Catch
+
+
+## 2.3.0
+
+**This release changes the include paths provided by our CMake and
+pkg-config integration. The proper include path for the single-header
+when using one of the above is now `<catch2/catch.hpp>`. This change
+also necessitated changes to paths inside the repository, so that the
+single-header version is now at `single_include/catch2/catch.hpp`, rather
+than `single_include/catch.hpp`.**
+
+
+
+### Fixes
+* Fixed Objective-C++ build
+* `-Wunused-variable` suppression no longer leaks from Catch's header under Clang
+* Implementation of the experimental new output capture can now be disabled (#1335)
+  * This allows building Catch2 on platforms that do not provide things like `dup` or `tmpfile`.
+* The JUnit and XML reporters will no longer skip over successful tests when running without `-s`  (#1264, #1267, #1310)
+  * See improvements for more details
+
+### Improvements
+* pkg-config and CMake integration has been rewritten
+  * If you use them, the new include path is `#include <catch2/catch.hpp>`
+  * CMake installation now also installs scripts from `contrib/`
+  * For details see the [new documentation](cmake-integration.md#top)
+* Reporters now have a new customization point, `ReporterPreferences::shouldReportAllAssertions`
+  * When this is set to `false` and the tests are run without `-s`, passing assertions are not sent to the reporter.
+  * Defaults to `false`.
+* Added `DYNAMIC_SECTION`, a section variant that constructs its name using stream
+  * This means that you can do `DYNAMIC_SECTION("For X := " << x)`.
+
+
+## 2.2.3
+
+**To fix some of the bugs, some behavior had to change in potentially breaking manner.**
+**This means that even though this is a patch release, it might not be a drop-in replacement.**
+
+### Fixes
+* Listeners are now called before reporter
+  * This was always documented to be the case, now it actually works that way
+* Catch's commandline will no longer accept multiple reporters
+  * This was done because multiple reporters never worked properly and broke things in non-obvious ways
+  * **This has potential to be a breaking change**
+* MinGW is now detected as Windows platform w/o SEH support (#1257)
+  * This means that Catch2 no longer tries to use POSIX signal handling when compiled with MinGW
+* Fixed potential UB in parsing tags using non-ASCII characters (#1266)
+  * Note that Catch2 still supports only ASCII test names/tags/etc
+* `TEST_CASE_METHOD` can now be used on classnames containing commas (#1245)
+  * You have to enclose the classname in extra set of parentheses
+* Fixed insufficient alt stack size for POSIX signal handling (#1225)
+* Fixed compilation error on Android due to missing `std::to_string` in C++11 mode (#1280)
+* Fixed the order of user-provided `FALLBACK_STRINGIFIER` in stringification machinery (#1024)
+  * It was intended to be replacement for built-in fallbacks, but it was used _after_ them.
+  * **This has potential to be a breaking change**
+* Fixed compilation error when a type has an `operator<<` with templated lhs (#1285, #1306)
+
+### Improvements
+* Added a new, experimental, output capture (#1243)
+  * This capture can also redirect output written via C apis, e.g. `printf`
+  * To opt-in, define `CATCH_CONFIG_EXPERIMENTAL_REDIRECT` in the implementation file
+* Added a new fallback stringifier for classes derived from `std::exception`
+  * Both `StringMaker` specialization and `operator<<` overload are given priority
+
+### Miscellaneous
+* `contrib/` now contains dbg scripts that skip over Catch's internals (#904, #1283)
+  * `gdbinit` for gdb `lldbinit` for lldb
+* `CatchAddTests.cmake` no longer strips whitespace from tests (#1265, #1281)
+* Online documentation now describes `--use-colour` option (#1263)
+
+
+## 2.2.2
+
+### Fixes
+* Fixed bug in `WithinAbs::match()` failing spuriously (#1228)
+* Fixed clang-tidy diagnostic about virtual call in destructor (#1226)
+* Reduced the number of GCC warnings suppression leaking out of the header (#1090, #1091)
+  * Only `-Wparentheses` should be leaking now
+* Added upper bound on the time benchmark timer calibration is allowed to take (#1237)
+  * On platforms where `std::chrono::high_resolution_clock`'s resolution is low, the calibration would appear stuck
+* Fixed compilation error when stringifying static arrays of `unsigned char`s (#1238)
+
+### Improvements
+* XML encoder now hex-encodes invalid UTF-8 sequences (#1207)
+  * This affects xml and junit reporters
+  * Some invalid UTF-8 parts are left as is, e.g. surrogate pairs. This is because certain extensions of UTF-8 allow them, such as WTF-8.
+* CLR objects (`T^`) can now be stringified (#1216)
+  * This affects code compiled as C++/CLI
+* Added `PredicateMatcher`, a matcher that takes an arbitrary predicate function (#1236)
+  * See [documentation for details](https://github.com/catchorg/Catch2/blob/master/docs/matchers.md)
+
+### Others
+* Modified CMake-installed pkg-config to allow `#include <catch.hpp>`(#1239)
+  * The plans to standardize on `#include <catch2/catch.hpp>` are still in effect
+
+
+## 2.2.1
+
+### Fixes
+* Fixed compilation error when compiling Catch2 with `std=c++17` against libc++ (#1214)
+  * Clara (Catch2's CLI parsing library) used `std::optional` without including it explicitly
+* Fixed Catch2 return code always being 0 (#1215)
+  * In the words of STL, "We feel superbad about letting this in"
+
+
+## 2.2.0
+
+### Fixes
+* Hidden tests are not listed by default when listing tests (#1175)
+  * This makes `catch_discover_tests` CMake script work better
+* Fixed regression that meant `<windows.h>` could potentially not be included properly (#1197)
+* Fixed installing `Catch2ConfigVersion.cmake` when Catch2 is a subproject.
+
+### Improvements
+* Added an option to warn (+ exit with error) when no tests were ran (#1158)
+  * Use as `-w NoTests`
+* Added provisional support for Emscripten (#1114)
+* [Added a way to override the fallback stringifier](https://github.com/catchorg/Catch2/blob/master/docs/configuration.md#fallback-stringifier) (#1024)
+  * This allows project's own stringification machinery to be easily reused for Catch
+* `Catch::Session::run()` now accepts `char const * const *`, allowing it to accept array of string literals (#1031, #1178)
+  * The embedded version of Clara was bumped to v1.1.3
+* Various minor performance improvements
+* Added support for DJGPP DOS crosscompiler (#1206)
+
+
+## 2.1.2
+
+### Fixes
+* Fixed compilation error with `-fno-rtti` (#1165)
+* Fixed NoAssertion warnings
+* `operator<<` is used before range-based stringification (#1172)
+* Fixed `-Wpedantic` warnings (extra semicolons and binary literals) (#1173)
+
+
+### Improvements
+* Added `CATCH_VERSION_{MAJOR,MINOR,PATCH}` macros (#1131)
+* Added `BrightYellow` colour for use in reporters (#979)
+  * It is also used by ConsoleReporter for reconstructed expressions
+
+### Other changes
+* Catch is now exported as a CMake package and linkable target (#1170)
+
+## 2.1.1
+
+### Improvements
+* Static arrays are now properly stringified like ranges across MSVC/GCC/Clang
+* Embedded newer version of Clara -- v1.1.1
+  * This should fix some warnings dragged in from Clara
+* MSVC's CLR exceptions are supported
+
+
+### Fixes
+* Fixed compilation when comparison operators do not return bool (#1147)
+* Fixed CLR exceptions blowing up the executable during translation (#1138)
+
+
+### Other changes
+* Many CMake changes
+  * `NO_SELFTEST` option is deprecated, use `BUILD_TESTING` instead.
+  * Catch specific CMake options were prefixed with `CATCH_` for namespacing purposes
+  * Other changes to simplify Catch2's packaging

-
-Catch is maintaining its own port in Microsoft's package manager [vcpkg](https://github.com/Microsoft/vcpkg). This means that when new version of Catch is released, it should be posted there as well. `updateVcpkgPackage.py` can do a lot of neccessary work for you, it creates a branch and commits neccessary changes. You should review these changes, push and open a PR against vcpkg's upstream.
-

+itself automagically, there are no optional steps at this time.

 Between tag expressions and wildcarded test names (as well as combinations of the two) quite complex patterns can be constructed to direct which test cases are run. If a complex pattern is used often it is convenient to be able to create an alias for the expression. This can be done, in code, using the following form:
 
-	CATCH_REGISTER_TAG_ALIAS( <alias string>, <tag expression> )
+    CATCH_REGISTER_TAG_ALIAS( <alias string>, <tag expression> )
 
 Aliases must begin with the `@` character. An example of a tag alias is:
 
-	CATCH_REGISTER_TAG_ALIAS( "[@nhf]", "[failing]~[.]" )
+    CATCH_REGISTER_TAG_ALIAS( "[@nhf]", "[failing]~[.]" )

 Catch needs to be able to convert types you use in assertions and logging expressions into strings (for logging and reporting purposes).

+## Catch::StringMaker specialisation
 If you don't want to provide an ```operator <<``` overload, or you want to convert your type differently for testing purposes, you can provide a specialization for `Catch::StringMaker<T>`:
 
 ```
 namespace Catch {
-	template<>
+    template<>

     };
 }
 ```
 
+## Catch::is_range specialisation
+As a fallback, Catch attempts to detect if the type can be iterated
+(`begin(T)` and `end(T)` are valid) and if it can be, it is stringified
+as a range. For certain types this can lead to infinite recursion, so
+it can be disabled by specializing `Catch::is_range` like so:
+
+```cpp
+namespace Catch {
+    template<>
+    struct is_range<T> {
+        static const bool value = false;
+    };
+}
+
+```
+
+
 ## Exceptions
 
 By default all exceptions deriving from `std::exception` will be translated to strings by calling the `what()` method. For exception types that do not derive from `std::exception` - or if `what()` does not return a suitable string - use `CATCH_TRANSLATE_EXCEPTION`. This defines a function that takes your exception type, by reference, and returns a string. It can appear anywhere in the code - it doesn't have to be in the same translation unit. For example:
 
 ```
 CATCH_TRANSLATE_EXCEPTION( MyType& ex ) {
-	return ex.message();
+    return ex.message();
 }
 ```
