Single Hpp File - v.7.0.0

See the v.7.0.0 milestone for the full list of changes.

• Breaking changes
  • If you are using Catch, we have changed the casing of the file that Approval Tests looks for, to be consistent with Catch downloads (#53). If you get build failures, you'll need to change your #include lines like this:

    -#include "Catch.hpp"
    +#include "catch.hpp"

  • If you pass in a reporter to CombinationApprovals::verifyAllCombinations(), the argument order has changed, and is now the first argument: see Passing in a Reporter. (#47 - thanks to @mika-fischer, Mika Fischer)
• New features
  • Support for the [Boost].UT test framework. See Using Approval Tests With [Boost].UT. (#58 - thanks to @lp55, Luiz Paulo M. Pires and @krzysztof-jusiak, Kris Jusiak)
  • Support for differencing tools in Tortoise Git. (#57 - thanks to @lp55, Luiz Paulo M. Pires)
• Bug fixes
  • Fixed tests failing when using Ninja generator used by Visual Studio 2019 (#55).
    • See Troubleshooting Misconfigured Build if you have test failures in your VS2019 builds.
  • Fixed unnecessary duplicate static functions. (#54)
  • Fixed ClipboardReporter on macOS. (#51)
  • Fixed inability to use project as sub-module on windows due to long filenames - by shortening the names of some files and folders in the tests. (#38)
