Bug Report Checklist
- I have read and agree to Mocha's Code of Conduct and Contributing Guidelines
- I have searched for related issues and issues with the
faqlabel, but none matched my issue. - I have 'smoke tested' the code to be tested by running it outside the real test suite to get a better sense of whether the problem is in the code under test, my usage of Mocha, or Mocha itself.
- I want to provide a PR to resolve this
Expected
When an uncaught error occurs during a test in browsers, you'd expect to see the call stack. That's useful.
Error: Oh no!
at inner (test.example.js:8:15)
Actual
Mocha's browser error handling code was written before browsers gave nice stacks (eb58761).
Error: Error: Oh no! (http://127.0.0.1:8081/test.example.js:8)
Minimal, Reproducible Example
Using a minimal browser setup such as in mochajs/mocha-examples#72:
it("example", (done) => {
function inner() {
throw new Error("Oh no!");
}
setTimeout(inner);
});Versions
Mocha: 10.3.0
Additional Info
This was filed long ago in #2167, then a fix proposed in #3952. Since #2167 is quite old, re-filing to be more current.
