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 for details
• Added support for compiling and running Catch without exceptions
  • Doing so limits the functionality somewhat
  • Look into the documentation 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
• 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 chars (#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

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 (#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 NoAssertion warnings
• operator<< is used before range-based stringification (#1172)
• Fixed -Wpedantic warnings (extra semicolons and binary literals) (#1173)

Improvements

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

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

• Experimental support for PCH was added (#1061)
• CATCH_CONFIG_EXTERNAL_INTERFACES now brings in declarations of Console, Compact, XML and JUnit reporters
• MatcherBase no longer has a pointless second template argument
• Reduced the number of warning suppressions that leak into user's code
  • Bugs in g++ 4.x and 5.x mean that some of them have to be left in

Fixes

2.0.1

Breaking changes

• Removed C++98 support
• Removed legacy reporter support
• Removed legacy generator support
  • Generator support will come back later, reworked
• Removed Catch::toString support
  • The new stringification machinery uses Catch::StringMaker specializations first and operator<< overloads second.
• Removed legacy SCOPED_MSG and SCOPED_INFO macros
• Removed INTERNAL_CATCH_REGISTER_REPORTER
  • CATCH_REGISTER_REPORTER should be used to register reporters
• Removed legacy [hide] tag
  • [.], [.foo] and [!hide] are still supported
• Output into debugger is now colourized
• *_THROWS_AS(expr, exception_type) now unconditionally appends const& to the exception type.
• CATCH_CONFIG_FAST_COMPILE now affects the CHECK_ family of assertions as well as REQUIRE_ family of assertions
  • This is most noticeable in CHECK(throws()), which would previously report failure, properly stringify the exception and continue. Now it will report failure and stop executing current section.
• Removed deprecated matcher utility functions Not, AllOf and AnyOf.
  • They are superseded by operators !, && and ||, which are natural and do not have limited arity
• Removed support for non-const comparison operators
  • Non-const comparison operators are an abomination that should not exist
  • They were breaking support for comparing function to function pointer
• std::pair and std::tuple are no longer stringified by default
  • This is done to avoid dragging in <tuple> and <utility> headers in common path
  • Their stringification can be enabled per-file via new configuration macros
• Approx is subtly different and hopefully behaves more as users would expect
  • Approx::scale defaults to 0.0
  • Approx::epsilon no longer applies to the larger of the two compared values, but only to the Approx's value
  • INFINITY == Approx(INFINITY) returns true

Improvements

• Reporters and Listeners can be defined in files different from the main file
  • The file has to define CATCH_CONFIG_EXTERNAL_INTERFACES before including catch.hpp.
• Errors that happen during set up before main are now caught and properly reported once main is entered
  • If you are providing your own main, you can access and use these as well.
• New assertion macros, *_THROWS_MATCHES(expr, exception_type, matcher) are provided
  • As the arguments suggest, these allow you to assert that an expression throws desired type of exception and pass the exception to a matcher.
• JUnit reporter no longer has significantly different output for test cases with and without sections
• Most assertions now support expressions containing commas (ie REQUIRE(foo() == std::vector<int>{1, 2, 3});)
• Catch now contains experimental micro benchmarking support
  • See projects/SelfTest/Benchmark.tests.cpp for examples
  • The support being experiment means that it can be changed without prior notice
• Catch uses new CLI parsing library (Clara)
  • Users can now easily add new command line options to the final executable
  • This also leads to some changes in Catch::Session interface
• All parts of matchers can be removed from a TU by defining CATCH_CONFIG_DISABLE_MATCHERS
  • This can be used to somewhat speed up compilation times
• An experimental implementation of CATCH_CONFIG_DISABLE has been added
  • Inspired by Doctest's DOCTEST_CONFIG_DISABLE
  • Useful for implementing tests in source files
    • ie for functions in anonymous namespaces
  • Removes all assertions
  • Prevents TEST_CASE registrations
  • Exception translators are not registered
  • Reporters are not registered
  • Listeners are not registered
• Reporters/Listeners are now notified of fatal errors
  • This means specific signals or structured exceptions
  • The Reporter/Listener interface provides default, empty, implementation to preserve backward compatibility
• Stringification of std::chrono::duration and std::chrono::time_point is now supported
  • Needs to be enabled by a per-file compile time configuration option
• Add pkg-config support to CMake install command

Fixes

• Don't use console colour if running in XCode
• Explicit constructor in reporter base class
• Swept out -Wweak-vtables, -Wexit-time-destructors, -Wglobal-constructors warnings
• Compilation for Universal Windows Platform (UWP) is supported
  • SEH handling and colorized output are disabled when compiling for UWP
• Implemented a workaround for std::uncaught_exception issues in libcxxrt
  • These issues caused incorrect section traversals
  • The workaround is only partial, user's test can still trigger the issue by using throw; to rethrow an exception
• Suppressed C4061 warning under MSVC

Internal changes

• The development version now uses .cpp files instead of header files containing implementation.
  • This makes partial rebuilds much faster during development
• The expression decomposition layer has been rewritten
• The evaluation layer has been rewritten
• New library (TextFlow) is used for formatting text to output

Older versions

1.12.x

1.12.2

Fixes

• Fixed missing include

1.12.1

Fixes

• Fixed deprecation warning in ScopedMessage::~ScopedMessage
• All uses of min or max identifiers are now wrapped in parentheses

• INFO messages are included in the xml reporter output even without -s specified.

1.11.x

1.11.0

Fixes

• The original expression in REQUIRE_FALSE( expr ) is now reporter properly as !( expr ) (#1051)
  • Previously the parentheses were missing and x != y would be expanded as !x != x
• Approx::Margin is now inclusive (#952)
  • Previously it was meant and documented as inclusive, but the check itself wasn't
  • This means that REQUIRE( 0.25f == Approx( 0.0f ).margin( 0.25f ) ) passes, instead of fails
• RandomNumberGenerator::result_type is now unsigned (#1050)

Improvements

• __JETBRAINS_IDE__ macro handling is now CLion version specific (#1017)
  • When CLion 2017.3 or newer is detected, __COUNTER__ is used instead of
• TeamCity reporter now explicitly flushes output stream after each report (#1057)
  • On some platforms, output from redirected streams would show up only after the tests finished running
• ParseAndAddCatchTests now can add test files as dependency to CMake configuration
  • This means you do not have to manually rerun CMake configuration step to detect new tests

1.10.x

1.10.0

Fixes

• Evaluation layer has been rewritten (backported from Catch 2)
  • The new layer is much simpler and fixes some issues (#981)
• Implemented workaround for VS 2017 raw string literal stringification bug (#995)
• Fixed interaction between [!shouldfail] and [!mayfail] tags and sections

• Added "wait-for-keypress" option

1.9.x

1.9.6

Improvements

• Catch's runtime overhead has been significantly decreased (#937, #939)
• Added --list-extra-info cli option (#934).
  • It lists all tests together with extra information, ie filename, line number and description.

1.9.5

Fixes

• Truthy expressions are now reconstructed properly, not as booleans (#914)
• Various warnings are no longer erroneously suppressed in test files (files that include catch.hpp, but do not define CATCH_CONFIG_MAIN or CATCH_CONFIG_RUNNER) (#871)
• Catch no longer fails to link when main is compiled as C++, but linked against Objective-C (#855)
• Fixed incorrect gcc version detection when deciding to use __COUNTER__ (#928)
  • Previously any GCC with minor version less than 3 would be incorrectly classified as not supporting __COUNTER__.
• Suppressed C4996 warning caused by upcoming updated to MSVC 2017, marking std::uncaught_exception as deprecated. (#927)

Improvements

• CMake integration script now incorporates debug messages and registers tests in an improved way (#911)
• Various documentation improvements

1.9.4

Fixes

• CATCH_FAIL macro no longer causes compilation error without variadic macro support
• INFO messages are no longer cleared after being reported once

Improvements and minor changes

  • Note that Catch still officially supports only ASCII

1.9.3

Fixes

• Completed the fix for (lack of) uint64_t in earlier Visual Studios

1.9.2

Improvements and minor changes

  • QNX does not support current enough (2001) POSIX specification
• JUnit no longer counts exceptions as failures if given test case is marked as ok to fail.
• Catch::Option should now have its storage properly aligned.
• Catch no longer attempts to define uint64_t on windows (#862)
  • This was causing trouble when compiled under Cygwin

Other

• Catch is now compiled under MSVC 2017 using std:c++latest (C++17 mode) in CI
• We now provide cmake script that autoregisters Catch tests into ctest.
  • See contrib folder.

1.9.1

Fixes

• Unexpected exceptions are no longer ignored by default (#885, #887)

1.9.0

Improvements and minor changes

• Catch no longer attempts to ensure the exception type passed by user in REQUIRE_THROWS_AS is a constant reference.
  • It was causing trouble when REQUIRE_THROWS_AS was used inside templated functions
  • This actually reverts changes made in v1.7.2
• Catch's Version struct should no longer be double freed when multiple instances of Catch tests are loaded into single program (#858)
  • It is now a static variable in an inline function instead of being an externed struct.
• Attempt to register invalid tag or tag alias now throws instead of calling exit().
  • Because this happen before entering main, it still aborts execution
  • Further improvements to this are coming
• CATCH_CONFIG_FAST_COMPILE now speeds-up compilation of REQUIRE* assertions by further ~15%.
  • The trade-off is disabling translation of unexpected exceptions into text.
• When Catch is compiled using C++11, Approx is now constructible with anything that can be explicitly converted to double.
• Captured messages are now printed on unexpected exceptions

Fixes:

• Clang's -Wexit-time-destructors should be suppressed for Catch's internals
• GCC's -Wparentheses is now suppressed for all TU's that include catch.hpp.
  • This is functionally a revert of changes made in 1.8.0, where we tried using _Pragma based suppression. This should have kept the suppression local to Catch's assertions, but bugs in GCC's handling of _Pragmas in C++ mode meant that it did not always work.
• You can now tell Catch to use C++11-based check when checking whether a type can be streamed to output.
  • This fixes cases when an unstreamable type has streamable private base (#877)
  • Details can be found in documentation

Other notes:

• We have added VS 2017 to our CI
• Work on Catch 2 should start soon

1.8.x

1.8.2

Improvements and minor changes

• TAP reporter now behaves as if -s was always set
  • This should be more consistent with the protocol desired behaviour.
• Compact reporter now obeys -d yes argument (#780)
  • The format is "XXX.123 s: " (3 decimal places are always present).
  • Before it did not report the durations at all.
• XML reporter now behaves the same way as Console reporter in regards to INFO
  • This means it reports INFO messages on success, if output on success (-s) is enabled.
  • Previously it only reported INFO messages on failure.
• CAPTURE(expr) now stringifies expr in the same way assertion macros do (#639)
• Listeners are now finally documented.
  • Listeners provide a way to hook into events generated by running your tests, including start and end of run, every test case, every section and every assertion.

Fixes:

• Catch no longer attempts to reconstruct expression that led to a fatal error (#810)
  • This fixes possible signal/SEH loop when processing expressions, where the signal was triggered by expression decomposition.
• Fixed (C4265) missing virtual destructor warning in Matchers (#844)
• std::strings are now taken by const& everywhere (#842).
  • Previously some places were taking them by-value.
• Catch should no longer change errno (#835).
  • This was caused by libstdc++ bug that we now work around.
• Catch now provides FAIL_CHECK( ... ) macro (#765).
  • Same as FAIL( ... ), but does not abort the test.
• Functions like fabs, tolower, memset, isalnum are now used with std:: qualification (#543).
• Clara no longer assumes first argument (binary name) is always present (#729)
  • If it is missing, empty string is used as default.
• Clara no longer reads 1 character past argument string (#830)
• Regression in Objective-C bindings (Matchers) fixed (#854)

Other notes:

• We have added VS 2013 and 2015 to our CI
• Catch Classic (1.x.x) now contains its own, forked, version of Clara (the argument parser).

  • Otherwise it is supressed for the whole TU
• Fixed test spec parser issue (with escapes in multiple names)

Other

• Various documentation fixes and improvements

1.7.x

1.7.2

Fixes and minor improvements

Xml:

(technically the first two are breaking changes but are also fixes and arguably break few if any people)

• C-escape control characters instead of XML encoding them (which requires XML 1.1)
• Revert XML output to XML 1.0
• Can provide stylesheet references by extending the XML reporter
• Added description and tags attributes to XML Reporter

• In SECTIONs the file/ line is now of the SECTION. not the TEST_CASE
• Added std:: qualification to some functions from C stdlib
• Removed use of RTTI (dynamic_cast) that had crept back in
• Silenced a few more warnings in different circumstances
• Travis improvements

1.7.1

Fixes:

• Fixed inconsistency in defining NOMINMAX and WIN32_LEAN_AND_MEAN inside catch.hpp.
• Fixed SEH-related compilation error under older MinGW compilers, by making Windows SEH handling opt-in for compilers other than MSVC.
  • For specifics, look into the documentation.
• Fixed compilation error under MinGW caused by improper compiler detection.
• Fixed XML reporter sometimes leaving an empty output file when a test ends with signal/structured exception.
• Fixed XML reporter not reporting captured stdout/stderr.
• Fixed possible infinite recursion in Windows SEH.

1.7.0

Features/ Changes:

• Catch now runs significantly faster for passing tests
  • Microbenchmark focused on Catch's overhead went from ~3.4s to ~0.7s.
  • Real world test using JSON for Modern C++'s test suite went from ~6m 25s to ~4m 14s.
• Catch can now run specific sections within test cases.
  • For now the support is only basic (no wildcards or tags), for details see the documentation.
• Catch now supports SEH on Windows as well as signals on Linux.
  • After receiving a signal, Catch reports failing assertion and then passes the signal onto the previous handler.
• Approx can be used to compare values against strong typedefs (available in C++11 mode only).
  • Strong typedefs mean types that are explicitly convertible to double.
• CHECK macro no longer stops executing section if an exception happens.
• Certain characters (space, tab, etc) are now pretty printed.
  • This means that a char c = ' '; REQUIRE(c == '\t'); would be printed as ' ' == '\t', instead of == 9.

Fixes:
