Testing CheckboxGroup

Test utils

@react-aria/test-utils offers common checkbox group interaction utilities which you may find helpful when writing tests. To install, simply add it to your dev dependencies via your preferred package manager.

Once installed, you can access the User that @react-aria/test-utils provides in your test file as shown below. This user only needs to be initialized once and then can be used to generate the CheckboxGroup tester in your test cases. This gives you access to CheckboxGroup specific utilities that you can then call within your test to query for specific subcomponents or simulate common interactions. The example test case below shows how you might go about setting up the CheckboxGroup tester, use it to simulate checkbox selection, and verify the checkbox group's state after each interaction.

// CheckboxGroup.test.ts
import {render} from '@testing-library/react';
import {User} from '@react-aria/test-utils';

let testUtilUser = new User({interactionType: 'mouse', advanceTimer: jest.advanceTimersByTime});
// ...

it('CheckboxGroup can select multiple checkboxes', async function () {
  // Render your test component/app and initialize the checkbox group tester
  let {getByTestId} = render(
    <CheckboxGroup data-testid="test-checkboxgroup">
    ...
    </CheckboxGroup>
  );
  let checkboxGroupTester = testUtilUser.createTester('CheckboxGroup', {root: getByTestId('test-checkboxgroup')});
  expect(checkboxGroupTester.selectedCheckboxes).toHaveLength(0);

  await checkboxGroupTester.toggleCheckbox({checkbox: 0});
  expect(checkboxGroupTester.checkboxes[0]).toBeChecked();
  expect(checkboxGroupTester.selectedCheckboxes).toHaveLength(1);

  await checkboxGroupTester.toggleCheckbox({checkbox: 4});
  expect(checkboxGroupTester.checkboxes[4]).toBeChecked();
  expect(checkboxGroupTester.selectedCheckboxes).toHaveLength(2);
});

See below for the full definition of the User and the CheckboxGroup tester.
