Since this isn't being used let's remove this import

I was testing some things out with the remaining two tests, missed removing it before pushing changes.

import { NavExpandable } from '../NavExpandable';
import { NavItem } from '../NavItem';

So for the purposes of this set of unit tests, we don't need any of these other Nav components. We really only want to test that NavExpandable behaves/works the way we expect. Sometimes that does involve importing other components/creating mocks, but for the tests relevant to this PR we can get away wthout them.

Oh great, reduced the code by a lot. I am new to writing tests so learning a lot.


const props = {
items: [
{ to: '#link1', label: 'Link 1' },
{ to: '#link2', label: 'Link 2' },
{ to: '#link3', label: 'Link 3' }
]
};

Currently I think we rarely use the describe block in our revamped tests; I personally try to use it more to separate out lengthy amounts of tests that can be grouped together. For now I think we can remove the describe block and just have each test on its own.

jest.resetAllMocks();

We shouldn't need this here

For the 2 tests here, with the above comments taken into account, we can slim down the code written:

  • Let's update the test names similar to how other revamped tests we have, along the lines of "Renders with the inert attribute by default" and "Does not render with the intert attribute when isExpanded is true".
  • For the render method, let's just pass a NavExpandable with a title prop passed in
  • For the expect, we can use the getByLabelText matcher using the string you pass to the title prop and then assert that the inert attribute is/isn't there.

Got it, will make the necessary changes.

const wrapper = screen.getByTestId('test-id');
const section = wrapper.querySelector('.pf-v6-c-nav__subnav');
expect(section).toHaveAttribute('inert', '');
