Wayland Conformance Test Suite
wlcs aspires to be a protocol-conformance-verifying test suite usable by Wayland compositor implementors. It is growing out of porting the existing Weston test suite to be run in Mir’s test suite, but it is designed to be usable by any compositor. wlcs relies on compositors providing an integration module, providing wlcs with API hooks to start a compositor, connect a client, move a window, and so on. This makes both writing and debugging tests easier - the tests are (generally) in the same address space as the compositor, so there is a consistent global clock available, it’s easier to poke around in compositor internals, and standard debugging tools can follow control flow from the test client to the compositor and back again.
