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)

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).

1.8.1

Fixes

Cygwin issue with gettimeofday - #define was not early enough

1.8.0

New features/ minor changes

• Matchers have new, simpler (and documented) interface.
  • Catch provides string and vector matchers.
  • For details see Matchers documentation.
• 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.
  • 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 and TestCase tags.
• Approx now supports an optional margin of absolute error
  • It has also received new documentation.

Fixes

• Silenced C4312 ("conversion from int to 'ClassName *") warnings in the evaluate layer.
• Fixed C4512 ("assignment operator could not be generated") warnings under VS2013.
• 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

1.7.2

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:

• REQUIRE_THROWS_AS now catches exception by const& and reports expected type
• 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.
• 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.
• 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.

Other:

• Catch's CMakeLists now defines install command.
• Catch's CMakeLists now generates projects with warnings enabled.

1.6.1

Features/ Changes:

• Catch now supports breaking into debugger on Linux

Fixes:

• Generators no longer leak memory (generators are still unsupported in general)
• JUnit reporter now reports UTC timestamps, instead of "tbd"
• CHECK_THAT macro is now properly defined as CATCH_CHECK_THAT when using CATCH_ prefixed macros

Other:

• Types with overloaded && operator are no longer evaluated twice when used in an assertion macro.
• The use of __COUNTER__ is supressed when Catch is parsed by CLion
  • This change is not active when compiling a binary
• Approval tests can now be run on Windows
• CMake will now warn if a file is present in the include folder but not is not enumerated as part of the project
• Catch now defines NOMINMAX and WIN32_LEAN_AND_MEAN before including windows.h
  • This can be disabled if needed, see documentation for details.

1.6.0

Cmake/ projects:

• Moved CMakeLists.txt to root, made it friendlier for CLion and generating XCode and VS projects, and removed the manually maintained XCode and VS projects.

Features/ Changes:

• Approx now supports >= and <=
• Can now use \ to escape chars in test names on command line
• Standardize C++11 feature toggles

Fixes:

• Blue shell colour
• Missing argument to CATCH_CHECK_THROWS
• Don't encode extended ASCII in XML
• use std::shuffle on more compilers (fixes deprecation warning/error)
• Use __COUNTER__ more consistently (where available)

Other:

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

Older versions

Release notes were not maintained prior to v1.6.0, but you should be able to work them out from the Git history
