All the functionality is already implemented in the app. transmission of data requires a response to the previous transmission This helps to save resources and provide more value to that individual test. Before this you could use `cy.server()` and `cy.route()`. Instead of actively checking (polling) if a separate thread has received HTTP response, TimeLimitedCodeBlock is waiting for a separate thread to terminate.

Software Quality Assurance & Testing Meta. One is to set a timeout for receiving a response. To wait for a specific amount of time or resource to resolve, use the cy. We want to stub the network call, with a fake one, so we can consistently reproduce the same results without relying on a potentially flakey external API. With this we were able to combine the two basic path checking tests we wrote into one test. Now we need to handle the dynamic stubbing part as well. I end up writing a test that looks something like this: I prepare my test state in beforeEach() hook, and to the rest in my it() block.
