Mantle's Test Framework uses traits to add optional functionality to a test case.

  • Refresh_Database - Using this trait ensures that the database is rolled back after each test in the test case has run. Without it, data in the database will persist between tests, which almost certainly would not be desirable. That said, if your test case doesn't interact with the database, omitting this trait will provide a significant performance boost.
  • Admin_Screen - Using this trait sets the current "screen" to a WordPress admin screen, and is_admin() will return true in tests in the test case
  • Network_Admin_Screen - Same as with Admin_Screen except for the network admin and is_network_admin()
