The idea of shipping a test server is to have something like Xvfb for
Wayland. To be able to run a test application with a fake Wayland server.
To make this super easy the test server binary is installed into libexec
directory and provides a cmake function to run a test application with
the test server.
The test server takes full control over the process. It's a guiless
application and starts the passed test application once it is fully
set up. The environment is setup to have the test application connect
to the fake server (WAYLAND_SOCKET env variable and QT_QPA_PLATFORM).
When the started application finishes the test server goes down and
exits with the exit value of the test application. This allows a good
integration with ctest.
The test server is a virtual server which supports the following
interfaces:
This is sufficient to bring up a QtWayland based application and
allows some basic interactions from a test application (e.g. fake
input).
So far the server fakes a repaint every 16 msec, but does not yet
pass events to the test applications.
To integrate this into an application for testing use:
find_package(KF5Wayland CONFIG) add_executable(myTest myTest.cpp) target_link_libraries(myTest Qt5::Gui Qt5::Test) kwaylandtest(myTest)
When now running ctest in the build directory the test server gets
started and will start the myTest binary and report the passed/failed
in the expected and normal way.
This way a test case can easily be run against both X11 and Wayland.
