When a build fail, the test run still succeeds

[BenoitZugmeyer]

When the build fail, for example because of a syntax error, karma-esbuild replaces it with a console.error, but does not fail the run. While it might be a good thing when running tests locally, it might be an issue in CI environments where we rely on test run exit status rather than error logs.

Would it be possible to fail the test run when a build fails?

Agree it should fail. Moreover, example to this kind of code that causes fail gracefully:

it("whatever", function() {
  export default "error";
});

Yup, please open a PR.
