  • 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

    • Catch specific CMake options were prefixed with CATCH_ for namespacing purposes
    • Other changes to simplify Catch2's packaging

2.1.0

Improvements

  • Various performance improvements
    • On top of the performance regression fixes
  • 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

    • One of the performance improvement patches for Catch classic was not applied to Catch2
  • Fixed platform detection for iOS (#1084)
  • Fixed compilation when g++ is used together with libc++ (#1110)

    • Regex matcher for strings, Matches.
    • Set-equal matcher for vectors, UnorderedEquals
    • Floating point matchers, WithinAbs and WithinULP.
  • Stringification now attempts to decompose all containers (#606)
    • Containers are objects that respond to ADL begin(T) and end(T).

Other changes

  • Reporters will now be versioned in the single_include folder to ensure their compatibility with the last released version

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

1.11.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
    • Previously sections with failing assertions would be marked as failed, not failed-but-ok

Improvements

  • Added libidentify support
  • 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

  • Catch now uses wmain when compiled under Windows and UNICODE 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 and Approx::operator() didn't.

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.

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.

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).

Fixes

Cygwin issue with gettimeofday - #define was not early enough

1.8.0

New features/ minor changes

  • Matchers have new, simpler (and documented) interface.
  • Changed console reporter test duration reporting format (#322)
    • Old format: Some simple comparisons between doubles completed in 0.000123s
    • New format: xxx.123s: Some simple comparisons between doubles (There will always be exactly 3 decimal places)
  • Added opt-in leak detection under MSVC + Windows (#439)
    • Enable it by compiling Catch's main with CATCH_CONFIG_WINDOWS_CRTDBG
  • 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.
  • XML reporter now reports filename as part of the Section and TestCase tags.
  • Approx now supports an optional margin of absolute error

  • Cygwin compatibility fixes
    • Signal handling is no longer compiled by default.
    • Usage of gettimeofday inside Catch should no longer cause compilation errors.
  • Improved -Wparentheses supression for gcc (#674)
    • When compiled with gcc 4.8 or newer, the supression is localized to assertions only
    • 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 attribites to XML Reporter
  • Tags are closed and the stream flushed more eagerly to avoid stdout interpolation

Other:

  • 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.
  • 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.

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.

  • Use __COUNTER__ more consistently (where available)

Other:

  • Tweaks and changes to scripts - particularly for Approval test - to make them more portable

Even Older versions
