Soli Deo gloria. Might it be faster? Removing the circular dependency resolved the issue. @matchatype In the case that you describe: Deep-equality matchers compare different instances of functions: If you think of the returned data structure as a tree, there is a difference between asserting a primitive value as a leaf, and asserting a function or symbol (when the caller does not provide it as an argument). I can see the paper clip symbol, showing an attachment. By default it looks for .js, .jsx, .ts and .tsx files inside of __tests__ folders, as well as any files with a suffix of .test or .spec (e.g. ReferenceError: You are trying to `import` a file after the Jest environment has been torn down. https://jestjs.io/docs/en/expect#expectanyconstructor, https://mongoosejs.com/docs/api.html#document_Document-toObject, [jest-dom-mocks] ⬆️ Update fetch-mock to latest, https://jestjs.io/docs/en/expect#tothrowerror.

If shallow copy of the array did not help, then the next step is something like: See https://mongoosejs.com/docs/api.html#document_Document-toObject. By the way you can actually test the throw message using regex: https://jestjs.io/docs/en/expect#tothrowerror. Answer expect.stringContaining(string) matches the received value if it is a string that contains the exact expected string. Returns a string containing a byte-stream representation of value that can be stored anywhere.

I had this problem too but I found I could wrap an expect inside of an expect and catch the throw error: I hope this helps someone. So we can trouble shoot: @sabriele From reading Jest code and guessing about MongoDB, users array might have non-index properties which toMatchObject should (but does not) ignore.
