Unit vs feature tests#

Laravel introduced feature tests as a concept, but under the hood they are actually integration tests. They should be used whenever testing a complete feature. For more simple tests, use unit tests.

E.g.:

A test class for a contact form, with the following assertions should be considered a feature test, since it tests multiple aspect of a contact form (success state, validation, notifications, etc.)

• testContactShouldRedirectIfSuccess
• testContactShouldReturn422IfInvalidEmailGiven
• testContactShouldReturn422IfNoEmailGiven
• testContactShouldReturn422IfNoMessageGiven
• testContactShouldSendNotificationIfSuccess

A test class for a registration form which only tests if a user has been created in the database, is considered a unit test.

• testRegistrationUserCreatedIfSuccess

Functional tests#

Functional test should be considered in addition to unit/feature tests when developing complex flows, such a multi-step registration process or a checkout process.
