This test case focuses on the lock screen. This is the screen that is shown when user session is locked, which allows unlocking.
How to test
- Log in to the GNOME desktop.
- Run some application, so that you can determine this session from a fresh new session (e.g. open a file browser or a text editor).
- Lock the user session. You have the following options of manual locking:
- from the system menu (top right corner)
- with the
- by searching for Lock Screen (or your local translation) item in the GNOME overview and clicking on it
- Wait for the screen to turn off.
- Wake up the screen by pressing a key or moving the pointer. You should see a lock screen containing current time and date.
- Try to unlock the session using wrong password. The screen should stay locked and show an error message.
- Unlock the session using the correct password. You should be back at your existing session with your running application.
- Lock the session again using a different method (see the list above).
- This time, click the "Log in as another user" button, you should be redirected to the login screen with a list of all available user accounts.
- Log in to your original account by selecting it and providing the correct password. You should be back at your existing session with your running application.
- If there are still some locking methods you haven't tried (see the list above), test the remaining methods one by one. Lock the desktop, then unlock it, and you should be back at your existing session with your running application.
- Go to Settings -> Privacy -> Screen Lock, and notice how long it takes for your system to blank the screen and then lock the screen. For testing purposes, you can lower that value to a minimum.
- Stop interacting with the desktop (no mouse movement, keyboard presses, etc) and measure the time. After the interval specified above, your screen should turn off and your session should lock. Move your mouse or press a keyboard key to verify that the screen is really locked.
- Unlock the screen. You should be back at your existing session with your running application.
- All attempted operations should finish successfully.
- When the screen is locked, it mustn't be possible to access your user session.
- Please report all failures to the GNOME tracker.
