Xen has a testsuite at https://xenbits.xen.org/gitweb/?p=osstest.git;a=summary that assures the quality of every commit or release and can be packaged and invoked in the xen build-time test (that only invokes 2 tests in Jammy!). If we also add the tests in the xen source package to the build-time test and add an autopkgtest that runs them, Xen now meets the requirements.
However, without looking at the testsuite, I doubt that the tests are covering API/ABI stability.
