Feature Testing¶
Feature testing validates that multiple components of a system work together correctly by simulating real user workflows, exercising the application through its public interface, via HTTP requests, console commands, or a browser, rather than calling internal classes directly.
In the test pyramid, feature tests sit above unit tests and below full end-to-end tests: they typically boot a real application kernel, hit routes or commands, and assert on the resulting response, database state, or emitted events, without necessarily driving a real browser.
PHP frameworks provide dedicated tooling for this style of testing: Laravel ships feature tests that extend Illuminate\Foundation\Testing\TestCase and can call routes via $this->get() or $this->post(); Symfony offers WebTestCase and Panther for browser-driven scenarios; Behat and Codeception let teams describe scenarios in Gherkin, with Given/When/Then, and run them against the real stack.
