v3.4.0

3.4.0

Improvements

• VectorEquals supports elements that provide only == and not != (#2648)
• Catch2 supports compiling with IAR compiler (#2651)
• Various small internal performance improvements
• Various small internal compilation time improvements
• XMLReporter now reports location info for INFO and WARN (#1251)
  • This bumps up the xml format version to 3
• Documented that SKIP in generator constructor can be used to handle empty generator (#1593)
• Added experimental static analysis support to TEST_CASE and SECTION macros (#2681)
  • The two macros are redefined in a way that helps the SA tools reason about the possible paths through a test case with sections.
  • The support is controlled by the CATCH_CONFIG_EXPERIMENTAL_STATIC_ANALYSIS_SUPPORT option and autodetects clang-tidy and Coverity.
• *_THROWS, *_THROWS_AS, etc now suppress warning coming from __attribute__((warn_unused_result)) on GCC (#2691)
  • Unlike plain [[nodiscard]], this warning is not silenced by void cast. WTF GCC?

Fixes

• Fixed assertionStarting events being sent after the expr is evaluated (#2678)
• Errors in TEST_CASE tags are now reported nicely (#2650)

Miscellaneous

• Bunch of improvements to catch_discover_tests
  • Added DISCOVERY_MODE option, so the discovery can happen either post build or pre-run.
  • Fixed handling of semicolons and backslashes in test names (#2674, #2676)
• meson build can disable building tests (#2693)
• meson build properly sets meson version 0.54.1 as the minimal supported version (#2688)
