This package does not come with a test suite, but its basic functionality can be tested after installation.

Now, as the root user: 

install -vm755 ../../target/release/libgstgtk4.so /usr/lib/gstreamer-1.0

To test the basic functionality of the package, issue: gst-launch-1.0 videotestsrc num-buffers=60 ! gtk4paintablesink in a graphical terminal emulator. It should play a test video in a GTK-4 window for 2 seconds.
