Crosier is a project for running GTest-based integration tests on a ChromeOS hardware Device Under Test (DUT) or in a ChromeOS Virtual Machine (VM). The idea is similar to interactive_ui_tests. A runner uses GTest to launch a full browser on DUT/VM, and the test body runs in the same process as the browser process. Utility APIs will be provided so the test body can access Chrome classes and objects like normal browser tests. The test can also access ChromeOS system services/daemons via utilities (D-Bus wrappers, shell commands, etc.).
Getting a DUT for local development is not easy for most developers and cros VM setup is harder than using the linux-chromeos “emulator” environment. We should limit the usage of Crosier and avoid DUT testing when possible. Running ChromeOS integration tests on DUT is only recommended for tests exercising hardware components (e.g. graphics tests) or testing communication with OS daemons (e.g. Bluetooth daemon).
