Testing RadioGroup

Test utils

@react-aria/test-utils offers common radio 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 RadioGroup tester in your test cases. This gives you access to RadioGroup 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 RadioGroup tester, use it to change radio selection, and verify the radio group's state after each interaction.

// RadioGroup.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('RadioGroup can switch the selected radio', async function () {
  // Render your test component/app and initialize the radiogroup tester
  let {getByRole} = render(
    <RadioGroup>
      ...
    </RadioGroup>
  );

  let radioGroupTester = testUtilUser.createTester('RadioGroup', {root: getByRole('radiogroup')});
  let radios = radioGroupTester.radios;
  expect(radioGroupTester.selectedRadio).toBeFalsy();

  await radioGroupTester.triggerRadio({radio: radios[0]});
  expect(radioGroupTester.selectedRadio).toBe(radios[0]);

  await radioGroupTester.triggerRadio({radio: radios[1]});
  expect(radioGroupTester.selectedRadio).toBe(radios[1]);
});

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