CSS Selectors to help integration testing

<Filmstrip /> component has optional testId: string property that will be assigned to the top level DOM element as data-testid attribute.

Here is the list of available css selectors ([data-test-...=""]) attributes that you might find useful to use in integration/e2e tests available in media-filmstrip:

Following three data-testid attributes are default values in case testId prop is undefined. Only one of these three can be found as a top DOM element:

• [data-testid="media-filmstrip"]: Root Filmstrip component
• [data-testid="media-filmstrip-list-item"]: Filmstrip item component
