clearImmediate is not defined error when using new v7.29.5 via cypress

[kschiffer]

• @testing-library/dom version: 7.29.5
• Testing Framework and version: cypress 4.11.0
• DOM Environment:
  Cypress Chrome 88

Relevant code or config:

Running any cypress test that uses @testing-library/cypress.

What you did:

Running cypress tests which worked before the update.

What happened:

 1) An uncaught error was detected outside of a test:
     ReferenceError: The following error originated from your test code, not from Cypress.

  > clearImmediate is not defined

Reproduction:

Running any cypress test that uses @testing-library/cypress.

Problem description:

The error originates from here: ac9a6b7#diff-49ba0c85360693b8e89ae0e0428284a55db749f08f2b9993d26910def646e02fR13

It appears like dom-testing-library assumes that clearImmediate and setImmediate are globally available, but it appears to be available in Internet Explorer 10 only.

Suggested solution:

I don't have time to look into why setImmediate is used in the first place, but I suppose that setImmediate needs to be removed or at least polyfilled before dom-testing-library uses it in the global scope.

Thanks for the report.

Could you try if this still happens with @testing-library/dom@7.29.6 ?

If the issue persists then we would need a reproduction to debug the issue. A link to a repository on GitHub, or provide a minimal code example that reproduces the problem.

Hello,

I had a similar issue and I confirm that by upgrading @testing-library/dom to 7.29.6 it solves it.

Thanks for the fix !
