Right now `TEMPLATE_TEST_CASE_SIG` fails to compile when the signature contains only types:
```
TEMPLATE_TEST_CASE_SIG(
"TemplateTestSig: compiles with two type parameters",
"[template][onlytypes]",
((typename U, typename V), U, V), (int,int)) {}
```
The trick is to resolve the ambiguity between the two overloads of
`get_wrapper` (`TypeList` and `Nttp`) by making one match more strongly.
We also need to allow `reg_test` to register more than one type.
Add unit tests.

Thanks. I made small changes for the tests to pass and to avoid polluting the global namespace with the priority tag. |

v3.9.0 === Improvements === * **Added experimental opt-in support for thread safe assertions** * Read the documentation for full details * **The default test run order has been changed to random** * Passing assertions are significantly faster when the reporter does not ask for `assertionEnded` events on passing assertions. * This is the default behaviour of e.g. Console or Compact reporter * Simple `REQUIRE(true)` is 60% faster in Release and 80% faster in Debug build configuration * Simple `REQUIRE_NOTHROW` is 230% faster in Release and 430% faster in Debug build configuration * Simple `REQUIRE_THROWS` is ~3% faster in Release and 20% faster in Debug build configuration (throwing introduces enough overhead that the optimizations inside Catch2 are mostly irrelevant) * Small (2-5%) improvement if the reporter asks for `assertionEnded` events for passing assertions. * The exit code constants are part of the Session API. (catchorg#2955, catchorg#2976) * Suppressed unsigned integer overflow checking in locations with intended overflow (catchorg#2965) * Reporters flush output after writing metadata, e.g. rng seed (catchorg#2964) * Added unreachable after `FAIL` and `SKIP` macros (catchorg#2941) * This allows the compiler to understand that the execution does not continue past the macro, and avoids warnings. * Added fast path for `assertionStarting` event when no reporter requires it * For backwards compatibility, this fast path is opt-in * A reporter can opt in by changing its `ReporterPreferences::shouldReportAllAssertionStarts` * Improved last seen source location tracking to be more precise * This is used when reporting unexpected exceptions from tests === Fixes === * Fixed formatting of tags with more than 100 tests in the default `--list-tags` output (catchorg#2963) * Fixed Clang-Tidy's `readability-static-accessed-through-instance` in tests * Fixed most of Clang-Tidy's `cppcoreguidelines-avoid-non-const-global-variables` (catchorg#2582) * The lifetime of scoped messages now strictly obeys their scope (catchorg#1759, catchorg#2019, catchorg#2959) * Previously Catch2 would try to keep them around during unexpected exception, to provide helpful context. * The amount of surprises the irregularities caused was not worth the occasional utility provided. * `TEMPLATE_TEST_CASE_SIG` can handle signatures consisting of only types (catchorg#2680, catchorg#2995) * Moved `catch_test_run_info.hpp` up from `internal/` subfolder into the main one (catchorg#2972) === Miscellaneous === * pkg-config files are now generated at install time (catchorg#2979) * This fixes missing debug suffix in library names * This fixes install prefix mismatch between build config and actuall installation # -----BEGIN PGP SIGNATURE----- # # iQIzBAABCgAdFiEE8QyLZSqAHw/oZQgX3kgwe4sNOBoFAmiCkWIACgkQ3kgwe4sN # OBrohA//VM0MoWEyb1Mp9Lw4pw07CL7EnqsgOnOjEu1EgN1tyDMEw3vf/uysiY4X # ab7RwVzCd0WVnixmNsduhzotCC0o4cDupPNXMTiRgO7ijtzLOfCsUqc+ZuIP0xUJ # a1IcokrQM/FYPfltBfJUCQdpWHX/Co0dDNtXlCjY2Ur3Ek/4w4M8efARKZi1xi+C # WDprUrOcYCWlYSzRa7LXWbkoCETdEphQCIXfCo8/kIbIf8+roJuiH/9RE6UrdeDY # yQfH6qLUoPdfeIQGGJY+dN+rVfsQkBBM2V6dsYcNsAXWsHEzDFJhI1KQHNw51T+3 # MSaGmUKa3ptwW8p+ecEsqdSiygMBmrVW+x1Oqk/FCuW1r7lDemnh9ZjyIt2PRfxO # 6AxTepyT2wJhjHK/UecIxhh7Xba7Cbbu9vT3FplJFtLI4MVgXFpo4hFKHGl2Y+oI # okJgoDb+Bh2sWqqFQdKfIq+0ntn8Oqfas64QV7jmT/M1f9ENMqrunEnmQzPGcu8t # ckly4+WVTCXAoSseKWJasJgFCPQjrjQYcaEtQNCNyYLSjLFJIMNmXp5NrlSmtLHv # va7JIMLEgar4kMuiRUeu3Tz0mDrWti4/eX503vBs/BF8/O8m6XKnv7vXcVhg2mQW # pLT5qM8bbAv0AnxHFgewD2ztuEoTPECqq6T06t77EHYDTPhys/4= # =6rlc # -----END PGP SIGNATURE----- # gpg: Signature made Thu Jul 24 22:02:42 2025 WEDT # gpg: using RSA key F10C8B652A801F0FE8650817DE48307B8B0D381A # gpg: Can't check signature: No public key # Conflicts: # extras/catch_amalgamated.cpp # extras/catch_amalgamated.hpp
