This is happening for two reasons: 1) expect, test and others are only auto-imported inside test files. Their use in util.ts is not a test file. I suspect we'll need to change these in the future to work more similar to Jest for compatibility 2) The above causes an exception, and some code somewhere appears to be ignoring the exception which leads to the error above

@Jarred-Sumner I have tried this again with 1.1. I have replaced all expect and test calls with bun:test imports. After another bunch of changes due to different testing framework bugs I now have tests passing. This specific test however still hangs and eats 100% CPU even though there is no error in console.
