If your JS tests are dependent on specifics in JavaScriptCore or V8 are you really writing unit tests? If you want the extra confidence, run it with bun:test and node:test to cover JSC and V8. But JS should be JS and for unit tests feeling a need to test on multiple JS engines is a possible code smell. | ||

Neither of the test libraries are specific to unit tests, so I don't quite understand that comment. That said, there are a lot more issues than just the differences between JSC and V8 - the Bun and NodeJS runtimes, while theoretically exposing the same modules, have a lot of practical differences that are visible in userland code, such as different exceptions, different orderings of queue events, etc. I imagine quite a lot of more complex code depends in some way on platform behaviours like these. | ||

Tests are about catching bugs, not playing no-true-Scotsman about what is or is not “unit test-y enough” to be a valid test. |
