Q$19.$ An application uses Momentjs library for date manipulation, which is available on windows object at global level. While testing a functionality using Jasmine, what a developer must do to test this functionality?

Options

$-$As it is available in app at windows object nothing needs to be done. Its reference will be available inside the test file and can be used easily

Developer must not test this functionality as it depends on other library

Moment needs to be included in the test explicitly and attached in windows object inside beforeEach method, then it be available during test run

Developer can mock it using a mock api and then use it
