good catch!

+    const { getByTestId, container } = render(<FormAutosuggestTestComponent />);
+    const input = getByTestId('autosuggest_textbox_input');
+    fireEvent.click(input);


[curious] Is there a reason to use fireEvent here (and elsewhere throughout the tests) versus using userEvent?

If it's possible to use userEvent.click instead, it's generally preferable since it simulates more of the true user interactions in the browser, not just the low-level click itself.

For example, userEvent.click also simulates a previous hover event that a real user would trigger prior to clicking.

+  it('renders without loading state', () => {
+    const { container } = render(<FormAutosuggestTestComponent />);
+    expect(container.querySelector('.pgn__form-autosuggest__dropdown-loading')).toBeNull();


Is there a way to avoid using the class name implementation detail in this test?

For example, if the component renders a Spinner with the supplied screenReaderText prop, could this test assert that the Spinner is not rendered based on a data-testid attribute versus relying on the class name that could change at any time. If the class name did change down the road, this test would still pass.

+  it('render with loading state', () => {
+    const { container } = render(<FormAutosuggestWrapper isLoading />);
+    expect(container.querySelector('.pgn__form-autosuggest__dropdown-loading')).toBeTruthy();


Similar to above comment, could we either assert that the screenReaderText passed to the Spinner is rendered, or alternatively, rely on a more stable data-testid instead of the class name?

LGTM!

So the current failing test is the error state test. It was written by having the simulated user enter the textbox and press escape. This worked before 4816baa#diff-96e13c1a773ec8d218ea5667d3dec6c8f6eeadcb00c81584f50d6c3d4d52135fL133, but now that doesn't trigger the error state.

It should probably be updated to simulate a click outside, as that will still trigger the error state (I verified on https://paragon-openedx.netlify.app/components/form/form-autosuggest/)

We recently rewrote all tests (except FormAutosuggest) to RTL. For uniformity of test identifiers, we agreed to use a kebab case. Can you convert the names of the identifiers to a uniform format? autosuggest-iconbutton

Is it better to move this line to setupTests.js? Did you encounter some problems with this?

@PKulkoRaccoonGang I'm sorry I was a bit hasty and didn't see these comments before hitting merge. We should be able to address them in a quick follow-up PR.
