Slow getByRole leads to test timeouts

[adrian-goe]

• @testing-library/react version: 13.4.0
• Testing Framework and version: "@nrwl/jest": "14.8.6"
• DOM Environment: "@testing-library/jest-dom": "5.16.5"

Relevant code or config:

instance.getByRole('button', {
  name: 'tests.actions.add', hidden: true
  })
).toBeEnabled();

What you did:

I create rederresult with act<RenderResult> and try to find some elements on the screen.

This, with other buttons, is called like 6 times in this one test

What happened:

We migrate our code from andt4 to antd5. As we did this we noticed a lot of our test time out. They time out, because getByRole() takes a lot of time. Sure, Antd is part of the problem, but the rendered result is a rendered result and that should work. The Test, I send in the reproduction part, is just rendering, with some fetchMocks, so no UI changes after the setup.

Reproduction:

I tried to create a good reproduction, but with all our setup code, its complex. So I created a playground with the actual screen render.

Problem description:

getByRole() takes a lot of time in this jest test. I used the profiler to get a feeling, on how long.

As you can see, for one getByRole() it takes around 1.6second. This adds up and leads to tests, that time out.

Suggested solution:

make getByRole fast 😅 I read a lot in the past weeks and someone said, this is slow (coudn't find the Issue again, sorry). I guess this could be improved.
