tests: Don't exit on first failure

[romanc]

Description

Tests currently exist as soon as one test fails. Other tests don't even run. Imo this doesn't make sense on the CI. I'd rather see all the failing tests at once.

How Has This Been Tested?

As part of PR #154, which had failing tests.

Longer feedback from the CI but we don't really code against it at the moment, so I don't mind. Will let NOAA go in.

Agreed. We were a little too cautious.
