ANON_TEST_CASE
has been removed, useTEST_CASE
with no arguments instead (#1220)--list*
commands no longer have non-zero return code (#1410)--list-test-names-only
has been removed (#1190)- You should use verbosity-modifiers for
--list-tests
instead

--list*
commands are now piped through the reporters- The top-level reporter interface provides default implementation that works just as the old one
- XmlReporter outputs a machine-parseable XML
TEST_CASE
description support has been removed- If the second argument has text outside tags, the text will be ignored.

is no longer type erased.- This means that the type of the provided predicate is part of the
PredicateMatcher
's type
- This means that the type of the provided predicate is part of the

SECTION("ShortName", "Long and wordy description")
, but the description is thrown away - The description type now must be a
const char*
or implicitly convertible to it

tag has been removed.- Use
[.]
or[.foo]
instead.

- They must still provide global
- Special cased
Approx(inf)
not to match non-infinite values- Very strictly speaking this might be a breaking change, but it should match user expectations better

WithinRel
- Unlike
- The ULP matcher now allows for any possible distance between the two numbers
- The random number generators now use Catch-global instance of RNG (#1734, #1736)
- This means that nested random number generators actually generate different numbers

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)

dup
ortmpfile
.

false
and the tests are run without-s
, passing assertions are not sent to the reporter. - Defaults to
false
.
- When this is set to
- Added
DYNAMIC_SECTION
, a section variant that constructs its name using stream- This means that you can do
DYNAMIC_SECTION("For X := " << x)
.
- This means that you can do
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

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
- This capture can also redirect output written via C apis, e.g.
- Added a new fallback stringifier for classes derived from
std::exception
- Both
StringMaker
specialization andoperator<<
overload are given priority
- Both

- The new stringification machinery uses
- Removed legacy
SCOPED_MSG
andSCOPED_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 appendsconst&
to the exception type.CATCH_CONFIG_FAST_COMPILE
now affects theCHECK_
family of assertions as well asREQUIRE_
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.
- This is most noticeable in
- Removed deprecated matcher utility functions
Not
,AllOf
andAnyOf
.- They are superseded by operators
!
,&&
and||
, which are natural and do not have limited arity
- They are superseded by operators
- 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
andstd::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
- This is done to avoid dragging in
Approx
is subtly different and hopefully behaves more as users would expectApprox::scale
defaults to0.0
Approx::epsilon
no longer applies to the larger of the two compared values, but only to theApprox
's valueINFINITY == 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.
- The file has to define
- 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
- See
- 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
- Inspired by Doctest's
- 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
andstd::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

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
- Previously the parentheses were missing and
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
- When CLion 2017.3 or newer is detected,
- 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

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

- 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 defineCATCH_CONFIG_MAIN
orCATCH_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__
.
- Previously any GCC with minor version less than 3 would be incorrectly classified as not supporting
- Suppressed C4996 warning caused by upcoming updated to MSVC 2017, marking
std::uncaught_exception
as deprecated. (#927)

- Various documentation improvements
1.9.4
Fixes
CATCH_FAIL
macro no longer causes compilation error without variadic macro supportINFO
messages are no longer cleared after being reported once
Improvements and minor changes
- Catch now uses
wmain
when compiled under Windows andUNICODE
is defined.- 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
- All of
Approx
's member functions now accept strong typedefs in C++11 mode (#888)- Previously
Approx::scale
,Approx::epsilon
,Approx::margin
andApprox::operator()
didn't.
- Previously
Fixes
- POSIX signals are now disabled by default under QNX (#889)
- 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.
- See
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
- It was causing trouble when
- 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
extern
ed struct.
- It is now a static variable in an inline function instead of being an
- 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 ofREQUIRE*
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 todouble
. - 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 includecatch.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_Pragma
s in C++ mode meant that it did not always work.
- This is functionally a revert of changes made in 1.8.0, where we tried using
- 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.
- This means it reports
CAPTURE(expr)
now stringifiesexpr
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::string
s are now taken byconst&
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.
- Same as
- Functions like
fabs
,tolower
,memset
,isalnum
are now used withstd::
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).

- Old format:
- Added opt-in leak detection under MSVC + Windows (#439)
- Enable it by compiling Catch's main with
CATCH_CONFIG_WINDOWS_CRTDBG
- Enable it by compiling Catch's main with
- Introduced new compile-time flag,
CATCH_CONFIG_FAST_COMPILE
, trading features for compilation speed.- Moves debug breaks out of tests and into implementation, speeding up test compilation time (~10% on linux).
- More changes are coming
- Added TAP (Test Anything Protocol) and Automake reporters.
- These are not present in the default single-include header and need to be downloaded from GitHub separately.
- For details see documentation about integrating with build systems.
- XML reporter now reports filename as part of the
Section
andTestCase
tags. Approx
now supports an optional margin of absolute error- It has also received new documentation.

- Otherwise it is suppressed 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
- Tags are closed and the stream flushed more eagerly to avoid stdout interpolation
Other:
REQUIRE_THROWS_AS
now catches exception byconst&
and reports expected type- In
SECTION
s the file/ line is now of theSECTION
. not theTEST_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
andWIN32_LEAN_AND_MEAN
insidecatch.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.
- Fixed possible compilation error caused by Catch's operator overloads being ambiguous in regards to user-defined templated operators.
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
.
- This means that a
Fixes:
- Text formatting no longer attempts to access out-of-bounds characters under certain conditions.
- THROW family of assertions no longer trigger
-Wunused-value
on expressions containing explicit cast. - Breaking into debugger under OS X works again and no longer required
DEBUG
to be defined. - Compilation no longer breaks under certain compiler if a lambda is used inside assertion macro.

include
folder but not is not enumerated as part of the project - Catch now defines
NOMINMAX
andWIN32_LEAN_AND_MEAN
before includingwindows.h
- This can be disabled if needed, see documentation for details.
