            I have a same problem too, but i am using a serialport not epoll.

            So, I think the cause of this problem is electron modules not the native module.

            Mock api response error object for redux toolkit
            Asked 2022-Feb-25 at 16:40

            I'm trying [redux toolkit][1] for the first time and haven't found helpful docs on how to test the ui response to api calls.

            I have seen [jest-fetch-mock][2] suggested for mocking the calls which are a bit hidden in syntactic sugar.

            currently my code works, but I can't find a good way to mock the 500 I should get from my api call to test a particular scenario. Here is the method that calls the api call in my RequestList.tsx file:

            Finally solved this! The docs for jest-fetch-mock are not very user friendly imo.

            Even though I am trying to mock an error I needed to use the mockResponse() function.

            fetchMock.mockResponse( JSON.stringify({ error: "Cannot read property 'state' of null" }), { status: 500 } )

            where { error: "Cannot read property 'state' of null" } is the body of the error message returned in the network tab.

            For some reason the mockReject() function makes assumptions about what the error body should look like, and it was very different from what my error looked like.

            Fetch is Undefined in Component when Mocking API Error Response with Jest
            Asked 2022-Jan-15 at 18:22

            I am testing a component that uses a useEffect hook that fetches data from an API, updates state and then builds out the component. I've mocked the API response successfully for several tests using this Stack Overflow answer as an example. I am now trying to write a test where I mock a returned error from the API. I'm getting an error stating TypeError: Cannot read property 'then' of undefined for fetch. I'm trying to use the same example but with no luck.

            My successful fetch mock with test data looks like:

            The difference I found is that, your successful fetch mock actually returns the Promise.

            But the failing fetch mock is not returning -- notice the subtle addition of curly braces around that Promise. Can you check this without that curly brackets?

            1. install babel-jest, babel-preset-env, @babel/runtime and react (the last one might be possible to be necessary only if some other package requires it)

            fetch-mock-jest .post resolves to {"size":0,"timeout":0}
            Asked 2021-Feb-03 at 02:09

            I am trying to unit test a function which sends a post request then the API returns a json object. I am trying to do this using jest and fetch-mock-jest.

            Now instead of the expected payload the tested function receives {"size":0,"timeout":0} and throws error invalid json response body at reason: Unexpected end of JSON input. Pretty sure there is something basic I don't see. I spent way more time on this without any progress than I'd like to admit.

            Edit: I am pretty new to jest and unit testing in general, so if someone has a better suggestion to go about mocking fetch, please tell me.

            You can use jest.mock(moduleName, factory, options) to mock isomorphic-unfetch module by yourself. Don't need fetch-mock-jest module.

            Regarding to your case, it looks pretty easy to deal with. You don't have to need any other package to mock your endpoint. You can mock axios directly via jest.
