Further reduce stamped out types for each templated test case

2026-08-23T18:46:39+00:00

This provides further speed-ups for TUs with many test cases templated
over the same set of types. For especially test-heavy (but still
realistic) TUs, the speed up is up to 20%.

Avoid stamping out common type helpers in each templated test cases

2026-08-23T09:31:50+00:00

This provides small (but measurable) improvements in compilation
times when a TU has multiple test cases templated over the same types.

Allow using only types in `TEMPLATE_TEST_CASE_SIG`. (#2995)

2025-07-08T12:26:25+00:00

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.

Fixes #2680

Fix references to license file

2022-10-28T09:30:15+00:00

The license file was renamed with 6a502cc2f5fedd59b3495b58708f0d6d987ed9e1

Split REMOVE_PARENS from catch_preprocessor.hpp

2022-04-15T15:14:28+00:00

This way, some headers can include just the new header, which
transitively decreases the total include size of test_macros.hpp.

Add standardized copyright notice + SPDX identifier to source files

2020-08-30T13:43:45+00:00

This should also be done for test files, but that has lower priority.

Standardize include guard patterns to FILE_NAME_EXTENSION_INCLUDED

2020-08-30T12:09:27+00:00

This commit also strips the old copyright comment header in touched
files, as those will also be replaced with a more standardized and
machine-friendly version.

Fix copy paste error in 7-arg TEMPLATE_TEST_CASE_SIG implementation

2020-07-22T19:18:52+00:00

Closes #1954

Standardize header names and file locations

2020-04-24T16:58:44+00:00

This is both a really big and a really small commit. It is small in
that it only contains renaming, moving and modification of include
directives caused by this.

It is really big in the obvious way of touching something like 200
files.

The new rules for naming files is simple: headers use the `.hpp`
extension. The rules for physical file layout is still kinda in
progress, but the basics are also simple:
 * Significant parts of functionality get their own subfolder
   * Benchmarking is in `catch2/benchmark`
   * Matchers are in `catch2/matchers`
   * Generators are in `catch2/generators`
   * Reporters are in `catch2/reporters`
   * Baseline testing facilities are in `catch2/`
 * Various top level folders also contain `internal` subfolder,
   with files that users probably do not want to include directly,
   at least not until they have to write something like their own
   reporter.
    * The exact files in these subfolders is likely to change later
      on

Note that while some includes were cleaned up in this commit, it
is only the low hanging fruit and further cleanup using automatic
tooling will happen later.

Also note that various include guards, copyright notices and file
headers will also be standardized later, rather than in this commit.
