* The purpose of this "unit test" is to verify a few invariants of the unit
* test framework itself, as well as to provide examples of output from actually
* failing tests. As such, it is intended that this test fails, and thus it
* should not be run as part of `make unit-tests`. Instead, we verify it behaves
* as expected in the integration test t0080-unit-test-output.sh
