We could perhaps customize `?` to help here, e.g. printing a trace or panic, with the `Try` trait or similar. Related to this: I thought about saying in the guidelines that `?` in tests is intended for things that you would normally use `?` in similar kernel code, i.e. things that the test is not "testing", rather than things that you would want to assert explicitly. Thus the actual code under test should still have `assert!`s in the right places. I did that in the sample. That way, having `?` would still simplify a lot of test code and yet allow us to differentiate between code under test vs. other code failing. > These changes don't depend on returning `Result` from the tests > AFAICT. Can they be in a separate patch? Not sure what you mean. The change below uses `?`, which is what allows this to be removed. Thanks! Cheers, Miguel
