// FullscreenControllerStateInteractiveTest ------------------------------------

// Interactive test fixture testing Fullscreen Controller through its states.
//
// Used to verify that the FullscreenControllerTestWindow models the behavior
// of actual windows accurately. The interactive tests are too flaky to run
// on infrastructure, and so those tests are disabled. Run them with:
//     interactive_ui_tests
//         --gtest_filter="FullscreenControllerStateInteractiveTest.*"
//         --gtest_also_run_disabled_tests
//
// More context atop fullscreen_controller_state_test.h.

// Soak tests ------------------------------------------------------------------

// Tests all states with all permutations of multiple events to detect lingering
// state issues that would bleed over to other states.
// I.E. for each state test all combinations of events E1, E2, E3.
//
// This produces coverage for event sequences that may happen normally but
// would not be exposed by traversing to each state via TransitionToState().
// TransitionToState() always takes the same path even when multiple paths
// exist.
