Traits

Introduction​

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

Refresh Database​

The Refresh_Database trait will ensure 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​

The Admin_Screen and Network_Admin_Screen traits will set the current "screen" to a WordPress admin screen, and is_admin() will return true in tests in the test case. This is useful for testing admin screens, or any code that checks is_admin().

Network Admin Screen​

The Network_Admin_Screen trait will set the current "screen" to a WordPress network admin screen, and is_network_admin() will return true in tests in the test case. This is useful for testing network admin screens, or any code that checks is_network_admin().

With Faker​

The With_Faker trait will add a $this->faker property to the test case with an instance of Faker. This is useful for generating test data.
