Running unit tests excluding a specific tag in Catch2

Question

Can I run test cases based on "not matching" a particular tag in Catch2 ?

TEST_CASE("Check the data validity","[Working]"){
  REQUIRE(true);
}

TEST_CASE("Check the input","[InProgress]"){
  REQUIRE(true);
}
TEST_CASE("Validate the response","[NotWorking]"){
  REQUIRE(false);
}

I want to invoke testcases that are not falling in [NotWorking] tag until I finish implementing that functionality.

Source: https://github.com/catchorg/Catch2/blob/master/docs/command-line.md#specifying-which-tests-to-run

Test case examples:

thisTestOnly            Matches the test case called, 'thisTestOnly'
"this test only"        Matches the test case called, 'this test only'
these*                  Matches all cases starting with 'these'
exclude:notThis         Matches all tests except, 'notThis'
~notThis                Matches all tests except, 'notThis'
~*private*              Matches all tests except those that contain 'private'
a* ~ab* abc             Matches all tests that start with 'a', except those that
                        start with 'ab', except 'abc', which is included

So in your case add to the command line:

exclude:NotWorking

or

~NotWorking

Answer 2

For your usecase of including the test, but expecting some assertions to fail you would be better off with the [!mayfail] tag.

See here :

[.mayfail] - doesn't fail the test if any given assertion fails (but still reports it), This can be useful to flag a work-in-progress. or a known issue that you don't want to immediately fix but still want to track in your tests.
