Restacking the frame for a window while unmanaging the window is harmless, but for undecorated (in particular, client-side-decorated) windows, this causes problems because the window is typically destroyed by the client immediately after withredrawing the window. Skip windows flagged as being unmanaged when assembling the new stack and when comparing the old order to the new stack. Add a stacking test for this. |

This directory implements a framework for automated tests of Mutter. The basic idea is that mutter-test-runner acts as the window manager and compositor, and forks off instances of mutter-test-client to act as clients. There's a simple scripting language for tests. A very small test would look like: --- # Start up a new X11 client with the client id 1 (doesn't have to be an integer) # Windows for this client will be referred to as 1/<window-id> new_client 1 x11 # Create and show two windows - again the IDs don't have to be integers create 1/1 show 1/1 create 1/2 show 1/2 # Wait for the commands we've executed in the clients to reach Mutter wait # Check that the windows are in the order we expect assert_stacking 1/1 1/2 --- Running ======= The tests are installed according to: https://wiki.gnome.org/Initiatives/GnomeGoals/InstalledTests if --enable-installed-tests is passed to configure. You can run them uninstalled with: cd src && make run-tests Command reference ================= The following commands are supported. Quoting and comments follow shell rules. new_client <client-id> [wayland|x11] Starts a client, connecting by either Wayland or X11. The client will subsequently be known with the given client-id (an arbitrary string) quit_client <client-id> Destroys all windows for the client, waits for that to be processed, then instructs the client to exit. create <client-id>/<window-id> [override|csd] Creates a new window. For the X11 backend, the keyword 'override' can be given to create an override-redirect and the keyword 'csd' can be given to create a client-side decorated window. show <client-id>/<window-id> hide <client-id>/<window-id> Ask the client to show (map) or hide (unmap) the given window activate <client-id>/<window-id> Ask the client to raise and focus the given window. This is currently a no-op for Wayland, where this capability is not supported in the protocol. local_activate <client-id>-<window-id> The same as 'activate', but the operation is done directly inside Mutter and works for both backends raise <client-id>/<window-id> lower <client-id>/<window-id> Ask the client to raise or lower the given window ID. This is a no-op for Wayland clients. (It's also considered discouraged, but supported, for non-override-redirect X11 clients.) destroy <client-id>/<window-id> Destroy the given window wait Wait until all requests sent by Mutter to clients have been received by Mutter, and then wait until all requests by Mutter have been processed by the X server. assert_stacking <client-id>/<window-id> <client-id>/<window-id> ... Assert that the list of client windows known to Mutter is as given and in the given order, bottom to top. This function also queries the X server stack and verifies that Mutter's expectation of the X server stack matches reality.
