Implement a simple TAP-based test engine in bash and a few basic tests using it, to be used to check for bugs and regressions. A new "check" target is added to the rtla Makefile that runs the test suite using the "prove" command implemented by Test::Harness. The only test format currently supported is running rtla with defined command arguments per test, checking its exit code. In case the exit code is non-zero, the output of rtla is displayed, together with the exit code. The test cases are adopted from rtla tests in the Continuous Kernel Integration (CKI) project [1] with the authors' approval.
