Catch v2.10.0 Release Notes

Release Date: 2019-10-13 // over 4 years ago

  • 🛠 Fixes

    • TEMPLATE_LIST_TEST_CASE now properly handles non-copyable and non-movable types (#1729)
    • 🛠 Fixed compilation error on Solaris caused by a system header defining macro TT (#1722, #1723)
    • REGISTER_ENUM will now fail at compilation time if the registered enum is too large
    • Removed use of std::is_same_v in C++17 mode (#1757)
    • 🛠 Fixed parsing of escaped special characters when reading test specs from a file (#1767, #1769)

    👌 Improvements

    • ✅ Trailing and leading whitespace in test/section specs are now ignored.
    • Writing to Android debug log now uses __android_log_write instead of __ android_log_print
    • 🌲 Android logging support can now be turned on/off at compile time (#1743)
      • The toggle is CATCH_CONFIG_ANDROID_LOGWRITE
    • ➕ Added a generator that returns elements of a range
      • Use via from_range(from, to) or from_range(container)
    • ➕ Added support for CRTs that do not provide std::nextafter (#1739)
      • They must still provide global nextafter{f,l,}
      • Enabled via CATCH_CONFIG_GLOBAL_NEXTAFTER
    • 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
    • The output of benchmarking through the Console reporter when --benchmark-no-analysis is set is now much simpler (#1768)
    • ➕ Added a matcher that can be used for checking an exceptions message (#1649, #1728)
      • The matcher helper function is called Message
      • The exception must publicly derive from std::exception
      • The matching is done exactly, including case and whitespace
    • ➕ Added a matcher that can be used for checking relative equality of floating point numbers (#1746)
      • Unlike Approx, it considers both sides when determining the allowed margin
      • Special cases NaN and INFINITY to match user expectations
      • The matcher helper function is called WithinRel
    • 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

    Miscellaneous

    • ⚡️ In-repo PNGs have been optimized to lower overhead of using Catch2 via git clone
    • Catch2 now uses its own implementation of the URBG concept
      • In the future we also plan to use our own implementation of the distributions from <random> to provide cross-platform repeatability of random results
