v2.7.0

Improvements

Fixes

Improvements

v2.4.2

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 (#1412)

v2.4.1

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)

v2.4.0

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 is what e.g. conan does)

v2.3.0

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).

v2.2.3

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)

v1.12.2

Fixes

• Fixed missing include
