            Check if a function was called in testing mode

            I have this javascript code that make a get request. It works fine.

            From your test, it's not entirely clear whether you know what getReq is supposed to do. You mock it out* to return 123, but assuming the implementation is mostly correct it would actually return a promise of an array of strings where each string is the first character of a sha (actually it returns undefined, because you don't return the promise chain, and maybe you actually wanted it to return the complete sha of the first commit rather than the first character of the sha for every commit?)

            Similarly in your previous attempt your mock for fetch didn't make sense:

            Executing priority of fetch() and setTimeout() in Chrome
            Asked 2020-May-19 at 12:14

            To my understanding of the event loop, the following code will output 'Sync 2' then 'Sync 4' first (synchronous code), then 'Promise 3' (fetch returns a Promise which would be placed in the microtask queue and will be executed after the synchronous code finishes and data comes back from the API), finally 'Async 1' (setTimeout would be placed in the macrotask/callback queue with the lowest priority).

            However, in the lastest version Chrome, I always got 'Async 1' before 'Promise 3' if I set setTimeout() to 0 like below. Is there anything I misunderstand? Is it possible that a not-yet-resolved Promise gets lower priority than something in the macrotask queue here?



            Answered 2020-May-19 at 12:14

            (fetch returns a Promise which would be placed in the microtask queue and will be executed after the synchronous code finishes and data comes back from the API)

            This is only true if the Promise that is returned resolves immediately - for example, with Promise.resolve. If the Promise returned by fetch resolved immediately, you'd be right, and the Promise 3 would log before the setTimeout's.

            But fetch does not resolve immediately - it requires the endpoint to respond first, and that takes some time, so you see the setTimeout log first.
