Tests failing in CI, CI shows as passing

[BobDickinson]

Describe the bug
When the CI job runs, the Tests target "Run all tests" has failing tests, but reports that it passes

To Reproduce
Review any recent CI run to see failing tests

Expected behavior
Tests should pass. If tests don't pass, CI shouldn't report Pass. These are two separate issues that both need to be fixed.
