Tests with jsdom/react don't seem to exit

[DavidWells]

Trying to use uvu + @testing-library/react for some fast tests 😃

However, it seems that uvu never exits once the tests are complete.

Here is a repro repo: https://github.com/DavidWells/uvu-jsdom-error-repro

If I comment out the component test https://github.com/DavidWells/uvu-jsdom-error-repro/blob/master/src/__tests__/index.js#L10-L27 uvu returns as expected.

Any ideas on how to fix this?

Thanks for the great lib as always ❤️

Running this in node v16.6.1 if that helps

Found another repro https://github.com/tommywalkie/uvu-jsdom-node-16-repro/tree/c5005cd6520ba27a334836bb862ba4307e719455 linked to #124 (comment)

The suggested fix works

test.after(() => {
  setTimeout(() => {
    process.exit(0)
  }, 500)
})

See #91 and #124 for related items. This means something isn't exiting itself (likely your jsdom hook) and uvu waits for everything to close before it exits.. since that's part of the testing responsibility.

If you look at the included svelte/Preact examples, there's a setup and teardown helper called for each suite, which is controlling the jsdom lifecycle to make sure it's not lingering.

In this case, it looks like the cause is the render function from @testing-library/react

@DavidWells Did you ever get to the bottom of the issue in @testing-library/react?
