This is my workaround: @manhhailua Thank you so much! @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). This matches most JSON naming conventions. expect.stringMatching(string | regexp) expect.stringMatching(string | regexp) matches the received value if it is a string that matches the expected string or regular expression. Hi @pedrottimark, I apologise for the tardy reply; this was a weekend project and I simply got swamped with work. expect.stringContaining(string) # expect.stringContaining(string) matches any string that contains the exact provided string.

How to read JSON as .NET objects (deserialize) To deserialize from a string or a file, call the JsonSerializer.Deserialize method.. 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. It will match received objects with properties that are not in the expected object. This is returned if the MAPI_TIMEOUT_SHORT flag was set and another thread held the mutex. to your account, Using .toMatchObject() returns failing test with message Received: serializes to the same string.

By clicking “Sign up for GitHub”, you agree to our terms of service and 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.
