  • On a (sort of) related issue, is there a Test:: module that will allow you to test only 1 or more tests from a large group of tests?

    For instance say test 99 of 100 starts failing and you would like to run it on its own. Is there any module that you can "use" to run only that test so that you don't see the output of the tests before or after. Something like:

            use Test::More tests => 100;
            use Test::Only '99'; ...

    • No, there's nothing like that. Part of the problem is that you get tests written like this:

      ok $some_test;
      # change the state
      ok $some_other_test;

      If you change the state between tests and only run the second test (and not code before it), this fails. You could write your own prove which only shows failing tests, but that will likely lose diagnostic information since that goes to STDERR.

      However, you can get this behavior if you're willing to switch to Test::Class. See Running Individual Tests [] in the documentation. It works by setting the TEST_METHOD environment variable to a regular expression which matches only those test methods you want to run.

      I have a vim mapping to automate setting the test method [].
