class: FetchRequest

This API is used for Web API testing. You can use it to trigger API endpoints, configure micro-services, prepare environment or the service to your e2e test. When used on [Page] or a [BrowserContext], this API will automatically use the cookies from the corresponding [BrowserContext]. This means that if you log in using this API, your e2e test will be logged in and vice versa.
