Add tests covering valid inputs, error scenarios (missing entrypoints, malformed JSON), and edge cases per [11730]. Place tests in `spec/javascript_main/tests/` following established patterns. </div> </div> <small><i>Code Review Run #75a90b</i></small> </div> --- Should Bito avoid suggestions like this for future reviews?
