### Automatic test registration ### Automatic test registration
If you are also using ctest, `contrib/ParseAndAddCatchTests.cmake` is a CMake script that attempts to parse your test files and automatically register all test cases, using tags as labels. This means that these We provide 2 CMake scripts that can automatically register Catch-based
tests with CTest,
* `contrib/ParseAndAddCatchTests.cmake`
* `contrib/CatchAddTests.cmake`
The first is based on parsing the test implementation files, and attempts
to register all `TEST_CASE`s using their tags as labels. This means that
these:
```cpp ```cpp
TEST_CASE("Test1", "[unit]") { TEST_CASE("Test1", "[unit]") {
int a = 1; int a = 1;

REQUIRE(a == b); REQUIRE(a == b);
} }
``` ```
would be registered as 3 tests, `Test1`, `Test2` and `Test3`, and 4 ctest labels would be created, `a`, `b`, `c` and `unit`. would be registered as 3 tests, `Test1`, `Test2` and `Test3`,
and 4 CTest labels would be created, `a`, `b`, `c` and `unit`.
The second is based on parsing the output of a Catch binary given
`--list-test-names-only`. This means that it deals with inactive
(e.g. commented-out) tests better, but requires CMake 3.10 for full
functionality.
