If env has REPO_TRACE 0, then the test produces: FileNotFoundError: No such file or directory: TRACE_FILE_from_test' because it assumes trace is always enabled. Improve by enabling trace for this test class. Also modify the repo_trace.SetTrace API to take an optional True/False if needed, still defaults to True though.
