/**
 * Fixture represents a fixed state of a test environment.
 *
 * Each fixture instance represents a particular aspect of a test environment. For example,
 * you may use `UserFixture` to initialize the user database table with a set of known data. You may
 * load the fixture when running every test method so that the user table always contains the fixed data
 * and thus allows your test predictable and repeatable.
 *
 * A fixture may depend on other fixtures, specified via the [[depends]] property. When a fixture is being loaded,
 * its dependent fixtures will be automatically loaded BEFORE the fixture; and when the fixture is being unloaded,
 * its dependent fixtures will be unloaded AFTER the fixture.
 *
 * You should normally override [[load()]] to specify how to set up a fixture; and override [[unload()]]
 * for clearing up a fixture.
