By setting @tag :capture_log before each test or @moduletag :capture_log for the whole test case, ExUnit will automatically capture anything that is logged while the test runs. set to true. Having a solutionmakes it easier to manage both the class library and the unit test project.Inside the solution directory, create a PrimeService directory. Here is an example (shamelessly copied from the Elixir 1.3 Change log) Our mock/stubbed function receives the file (in this case it’s just a content in the form of a string), which we send back to the test using its PID we bound a couple of lines earlier. I needed to test that an output PDF looks visually the same as what is expected. Mutation testing work almost the exact same, you construct your mutation and send it and then test for what gets returned or set in the database. In order to test it I figured I would create another directory (example_tests) containing a test_helper.exs file with similar to the one in test/, but with ExUnit configured to use my custom formatter.

AssertHTML adds ExUnit assert helpers for testing rendered HTML using CSS selectors. Cela dit, un test de passage revient toujours :ok , mais, plus important encore, il force Elixir à ne pas caller l'optimisation du test et évite donc de cacher les lignes du backtrace. Un autre cas d'utilisation pour les balises et les filtres est d'exclure tous les tests qui ont une balise particulière par défaut, indépendamment de sa valeur, et d'inclure seulement un certain sous-ensemble: Gardez à l'esprit que tous les tests sont inclus par défaut, donc à moins qu'ils ne soient exclus en premier, l'option d' include n'a aucun effet.
