# FIXTURES_CLEANUP

Specifies a list of fixtures for which the test is to be treated as a cleanup test.

Fixture cleanup tests are ordinary tests with all of the usual test functionality. Setting the `FIXTURES_CLEANUP` property for a test has two primary effects:

- CTest will ensure the test executes after all other tests which list any of the fixtures in its `FIXTURES_REQUIRED` property.
- If CTest is asked to run only a subset of tests (e.g. using regular expressions or the `--rerun-failed` option) and the cleanup test is not in the set of tests to run, it will automatically be added if any tests in the set require any fixture listed in `FIXTURES_CLEANUP`.

A cleanup test can have multiple fixtures listed in its `FIXTURES_CLEANUP` property. It will execute only once for the whole CTest run, not once for each fixture. A fixture can also have more than one cleanup test defined. If there are multiple cleanup tests for a fixture, projects can control their order with the usual `DEPENDS` test property if necessary.

A cleanup test is allowed to require other fixtures, but not any fixture listed in its `FIXTURES_CLEANUP` property. For example:

    # Ok: Dependent fixture is different to cleanup
    set_tests_properties(cleanupFoo PROPERTIES
      FIXTURES_CLEANUP  Foo
      FIXTURES_REQUIRED Bar
    )

    # Error: cannot require same fixture as cleanup
    set_tests_properties(cleanupFoo PROPERTIES
      FIXTURES_CLEANUP  Foo
      FIXTURES_REQUIRED Foo
    )

Cleanup tests will execute even if setup or regular tests for that fixture fail or are skipped.

See `FIXTURES_REQUIRED` for a more complete discussion of how to use test fixtures.
