We have bash-5.0.7.1 present in the buildenviroment. Full log:

This just happened to us on Solaris as well. AFAICT the test case incorrectly assumes that there are always some set aliases, but that doesn't have to true.

The fix is either:

1. choose a different build-in bash command
2. call something like bash.run_command("alias a='b'") to make sure, that at least one alias exists.

Similarly, the REPLWrapTestCase.test_bash_env test assumes there is PS1 always in the env output which is not the case, so the test could fail as well.
