gojson processing passes failing tests

[Ben]

What steps did you take and what happened:
We had a test fail in the Setup phase, meaning that the logs show a failure, but the plugin detects a passed test.

What did you expect to happen:
We expect that the test is reported as failing

Anything else you would like to add:
Here are (sanitised) test logs. The only change made was renaming the package.

This happens on the current main version.
