3.8. If a test fails, I'd like to put all of my debugging information into the final result. How do I do that?

The final result string is composed by the harness. For tests that fail because an exception is thrown, the result string will contain some header string such as `main' threw exception: followed by the exception's type and detail message. This detail message should contain sufficient information to provide the test user a starting point to investigate the unexpected failure. It should not contain full debugging information.

The harness makes no guarantees as to the availability of any detail message longer than 128 characters.
