Testing GridList

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

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.getRows()[0];
  expect(within(row).getByRole('checkbox')).not.toBeChecked();
  expect(gridListTester.getSelectedRows()).toHaveLength(0);

  await gridListTester.toggleRowSelection({row: 0});
  expect(within(row).getByRole('checkbox')).toBeChecked();
  expect(gridListTester.getSelectedRows()).toHaveLength(1);

  await gridListTester.toggleRowSelection({row: 0});
  expect(within(row).getByRole('checkbox')).not.toBeChecked();
  expect(gridListTester.getSelectedRows()).toHaveLength(0);
});

API

User

Properties

NameTypeDefault
interactionType['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.

advanceTimer['advanceTimer']Default: —

A function used by the test utils to advance timers during interactions. Required for certain aria patterns (e.g. table).

Methods

constructor(opts: ): void
createTester<T extends >(patternName: T, opts: <T>): <T>
Creates an aria pattern tester, inheriting the options provided to the original user.

GridListTester

constructor(opts: ): void
setInteractionType(type: ['interactionType']): void
Set the interaction type used by the gridlist tester.
findRow(opts: {
indexOrText: number | string
}): HTMLElement
Returns a row matching the specified index or text content.
toggleRowSelection(opts: ): Promise<void>
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(opts: ): Promise<void>
Triggers the action for the specified gridlist row. Defaults to using the interaction type set on the gridlist tester.
getGridlist(): HTMLElement
Returns the gridlist.
getRows(): HTMLElement[]
Returns the gridlist's rows if any.
getSelectedRows(): HTMLElement[]
Returns the gridlist's selected rows if any.
getCells(opts: {
element?: HTMLElement
}): HTMLElement[]
Returns the gridlist's cells if any. Can be filtered against a specific row if provided via element.
