Of course I did. What do you mean exactly?

@boastful-squirrel No known programming language in existence can achieve what you described. And integration tests weren't meant to do that either. Integration tests are meant to act as a user, use the program like a user, and expect to see what a user sees. So you are not meant to access ContextualError as a Rust objects, only as a string. For Rust objects, you should use unit tests.
