@react-aria/test-utils offers common checkbox group interaction testing utilities. Install it with your preferred package manager.
Initialize a User object at the top of your test file, and use it to create an CheckboxGroup pattern tester in your test cases. The tester has methods that you can call within your test to query for specific subcomponents or simulate common interactions.
// CheckboxGroup.test.tsimport {render} from'@testing-library/react';
import {User} from'@react-aria/test-utils';
lettestUtilUser = new User({
interactionType: 'mouse',
advanceTimer: jest.advanceTimersByTime
});
// ...it('CheckboxGroup can select multiple checkboxes', asyncfunction () {
// Render your test component/app and initialize the checkbox group testerlet {getByTestId} = render(
<CheckboxGroup data-testid="test-checkboxgroup">
...
</CheckboxGroup>
);
letcheckboxGroupTester = testUtilUser.createTester('CheckboxGroup', {root: getByTestId('test-checkboxgroup')});
expect(checkboxGroupTester.selectedCheckboxes).toHaveLength(0);
awaitcheckboxGroupTester.toggleCheckbox({checkbox: 0});
expect(checkboxGroupTester.checkboxes[0]).toBeChecked();
expect(checkboxGroupTester.selectedCheckboxes).toHaveLength(1);
awaitcheckboxGroupTester.toggleCheckbox({checkbox: 4});
expect(checkboxGroupTester.checkboxes[4]).toBeChecked();
expect(checkboxGroupTester.selectedCheckboxes).toHaveLength(2);
});

Testing FAQ
In cases like this, first double check your test setup and make sure that your test is rendering your checkbox group in its expected state before the test util interaction call. If everything looks correct, you can always fall back to simulating interactions manually, and using the test util to query your checkbox group's state post interaction.
Whenever the checkbox group tester queries its elements or triggers a user flow, it does so against the current state of the checkbox group. Therefore the checkbox group tester can be used alongside whatever simulated user flow you add.
