  • Brief description:
    • Have you ever wanted an API that could dramatically simplify the process of writing Drupal unit tests? There’s a module for that.
  • Module name/project name:
  • Brief history
    • How old: created in Sep 2022 by today’s guest, Alexey Korepov
    • Versions available: 1.3.0 compatible with versions of Drupal 9.4 or newer, right up to Drupal 11
  • Maintainership
    • Actively maintained, latest release less than 3 months ago
    • Security coverage
    • Test coverage, would be ironic if it didn’t
    • API Documentation is available, linked from the project page
    • Number of open issues: 2 open issues, which are actually feature requests
  • Usage stats:
    • 5 sites officially, but modules or sites can leverage Test Helpers without enabling it, and this usage is recommended, so the number is actually higher
  • Module features and usage
    • Provides a new container that automated tests can leverage to perform common tasks with much less code.
    • For example, you can create a user or a node with a single line of code
    • You can also mock more complex operations like an entityQuery or loadMultiple call, again with a single line of code
    • Traditionally, writing unit tests is more complicated because by design they run without fully bootstrapping Drupal
    • That means that your test needs to mock functions or services in the code you’re testing which can result in units tests being much longer than the code they’re testing
    • Test Helpers also allows your tests to leverage existing mocks and stubs for popular services
    • The project page also links to the recording and slides for a talk Alexey gave about Test Helpers at DrupalCon Pittsburgh last year, if you want to do a deeper dive
