Summary

120 seconds is an extremely long timeout when running locally and having failures. It would be good to only set the 120 seconds on CI/remote systems and have a shorter 10-20 second timeout for most contributors with reasonable CPU architectures.

Labeling good first issue because it is very contained and should likely just need some investigation into environment variables and detecting platforms we are running on.

Proposed fix

Set the _test_timeout variable differently depending on whether we are running on CI or not.
