What happened:

Tests couldn’t be executed, the following error was thrown:

Reproduction:

Problem description:

@testing-library/dom 7.22.3 was working fine.

@testing-library/dom 7.22.6 doesn’t work.

Suggested solution:

I can see there was a bump of pretty-format between 7.22.3 and 7.22.6: https://github.com/testing-library/dom-testing-library/commit/9cbc4280d4eceddc5511c21114455f73cd31d196, perhaps it’s the culprit.

Adding this dev dep solves the error for me (jest 27) "jest-environment-jsdom": "~27.0"

[sibelius]

this is a problem only when running tests with jest 27
