fix: Do not exit in test environment

[chloe463]

Hi!

Thank you for creating this useful GitHub Action! I've found it to be incredibly helpful.

However, I encountered an issue while running the tests. Specifically, the test suite seems to exit prematurely, resulting in some tests not being executed.

This PR aims to address this issue and ensure that all tests are run to completion. I would appreciate your review and feedback. Thank you!
