Mocha w/React Testing Library is not respecting expect(null).to.be.null within wait/waitForElement
I’m using the combination of Mocha and React Testing Library for acceptance testing (not my choice) and have a situation where I need to use wait or waitForElement to ultimately verify the absence of an element in the DOM. (Yes, as per React Testing Library’s documentation, I’m using getByTestId to attempt this.) There are multiple asynchonous operations that include fetch requests which occur in rapid succession (e.g., the user logs in then clicks/selects some things before submitting a form, which causes another UI to render). After all of that, there’s my expect, which is supposed to verify the absence of an element from within React Testing Library’s wait. The problem is that I can neither resolve so much as expect(null).to.be.null nor expect(null).to.not.be.null from within wait.
These fail:
describe(‘My app’, function () {
it(‘Does things’, async function () {
await wait(() => {
expect(null).to.be.null
})
})
})
describe(‘My app’, function () {
it(‘Does things’, async function () {
await wait(() => {
expect(null).to.not.be.null
})
})
})
What could I be doing wrong?

Can you share a reproducible example in codesandbox or something similar?
