My experience with XCTest and optionals recently was that XCTest runs in a separate process and reloads the application for subsequent tests. I auto-converted some Java code and added force-unwrap everywhere as a first stage. The offending optionals get fixed quite fast and I don’t think they are meant to be part of the testing process. I agree you might want to have a “fatal error” test case though, to be sure your application doesn’t accept strange input. If you really need this now, there seems to be a library for it - https://github.com/mohamede1945/AssertionsTestingExample.
