    Mocks Server monorepo (by mocks-server)

    Project mention: My code is always buggy | | 2022-06-29

    Here's an example of a test that covers a lot: Let's say that you have a view that shows a list of users. To get those users you would most likely have a backend that has some API. You can request that API with Postman, that way you know that your request is valid, and you get a very realistic response (assuming this is a test environment or whatever. Just don't use production data). Then you use something like MockServer and set up the request as expectation and the response as what should be returned. After that, you can write a test that verifies that the correct number (with some tactically chosen verification of values) of users show up in the list. Now you have a test that covers a huge portion of the codebase, while being very user-centric and easy to maintain.
