By default, RTK Query ships with fetchBaseQuery, which is a lightweight fetch wrapper that automatically handles request headers and response parsing in a manner similar to common libraries like axios. When you perform a query, RTK Query automatically serializes the request parameters and creates an internal queryCacheKey for the request. RTK Query is a powerful data fetching and caching tool. See Customizing Queries if fetchBaseQuery does not handle your requirements. The primary benefit is that you get a render-optimized hook that allows you to have 'background fetching' as well as derived booleans for convenience. useMutation doesn't execute automatically. Query endpoints should define either a query callback that constructs the URL (including any URL query params), or a queryFn callback that may do arbitrary async logic and return a result. MSW configuration <rootDir>/jestSetup.js I think that your comment here correctly identified this issue (and clarified that it pertains to SuperTokens, not RTK Query). Software engineer at Microsoft.

Note that a shallow equality check is performed on the overall return value of selectFromResult to determine whether to force a rerender. Spanish - How to write lm instead of lim?

We first test that the request is hitting the API correctly by accessing the Request object that is passed to fetchMock and checking the headers, method, and URL that are used. This distinction allows for greater control when handling UI behavior.
