General setup
GridList supports long press interactions on its items in certain configurations. See the following sections on how to handle these behaviors in your tests.
Test utils
@react-aria/test-utils offers common gridlist interaction testing utilities. Install it with your preferred package manager.
npm install @react-aria/test-utils --dev
Requirements
Please note that this library uses @testing-library/react@16 and @testing-library/user-event@14. This means that you need to be on React 18+ in order for these utilities to work.
Initialize a User object at the top of your test file, and use it to create a GridList 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.
// GridList.test.ts
import {render, within} from '@testing-library/react';
import {User} from '@react-aria/test-utils';
let testUtilUser = new User({
interactionType: 'mouse'
});
// ...
it('GridList can select a row via keyboard', async function () {
// Render your test component/app and initialize the gridlist tester
let {getByTestId} = render(
<GridList data-testid="test-gridlist" selectionMode="single">
...
</GridList>
);
let gridListTester = testUtilUser.createTester('GridList', {root: getByTestId('test-gridlist'), interactionType: 'keyboard'});
let row = gridListTester.rows[0];
expect(within(row).getByRole('checkbox')).not.toBeChecked();
expect(gridListTester.selectedRows).toHaveLength(0);
await gridListTester.toggleRowSelection({row: 0});
expect(within(row).getByRole('checkbox')).toBeChecked();
expect(gridListTester.selectedRows).toHaveLength(1);
await gridListTester.toggleRowSelection({row: 0});
expect(within(row).getByRole('checkbox')).not.toBeChecked();
expect(gridListTester.selectedRows).toHaveLength(0);
});
API
User
Properties
| Name | Type | Default |
|---|---|---|
advanceTimer | UserOpts['advanceTimer'] | Default: — |
| A function used by the test utils to advance timers during interactions. Required for certain aria patterns (e.g. table). | ||
interactionType | UserOpts['interactionType'] | Default: mouse
|
| The interaction type (mouse, touch, keyboard) that the test util user will use when interacting with a component. This can be overridden at the aria pattern util level if needed. | ||
Methods
constructor | ||
createTester | ||
| Creates an aria pattern tester, inheriting the options provided to the original user. | ||
GridListTester
Properties
| Name | Type | |
|---|---|---|
selectedRows | HTMLElement | |
| Returns the gridlist's selected rows if any. | ||
rows | HTMLElement | |
| Returns the gridlist's rows if any. | ||
gridlist | HTMLElement | |
| Returns the gridlist. | ||
Methods
constructor | ||
setInteractionType | ||
| Set the interaction type used by the gridlist tester. | ||
findRow | ||
| Returns a row matching the specified index or text content. | ||
toggleRowSelection | ||
| Toggles the selection for the specified gridlist row. Defaults to using the interaction type set on the gridlist tester. Note that this will endevor to always add/remove JUST the provided row to the set of selected rows. | ||
triggerRowAction | ||
| Triggers the action for the specified gridlist row. Defaults to using the interaction type set on the gridlist tester. | ||
cells | ||
Returns the gridlist's cells if any. Can be filtered against a specific row if provided via element. | ||
