阅读更多关于 Testing Redux Thunk Action Creator

问题 I've got a redux action creator that utilizes redux-thunk to do some logic to determine what to dispatch to the store. Its not promise-based, like an HTTP request would be, so I am having some issues with how to test it properly. Ill need a test for when the value meets the condition and for when it doesn't.

I'm trying to write some test using react, redux-mock-store and redux, but I keep getting and error. Maybe because my Promise has not yet been resolved? The fetchListing() action creator actually works when I try it on dev and production, but I'm having problems making the test pass. error message (node:19143) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 3): SyntaxError (node:19143) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated.
