[Code/Astro] Secret code given after any number of successful test completions

[hmperk18]

Describe the bug
When running the tests to get the secret code for Code/Astro, I found that if you Crtl+C while the tests are running, I was still given the code because, even though not all of them ran, the ones that did complete were successful. The flag only checks if there was no fail, rather than all were successful.

To Reproduce
Steps to reproduce the behavior:

1. Run all of the tests with --mode=codeastro
2. Anytime before the last one completes, kill the process
3. get the secret code prematurely
