-        This does not verify model output or predictions (it's a fake MLflow model, after all); it's up to the real model
-        to output its predictions as it wants, but this is specific to the model and so not tested here.
-
-        The  CliRunner() invokes the subcommand in a subprocess, and the annotate subcommand itself invokes the MLflow
-        model in yet another subprocess. So while this test can help determine if everything is working, it is not a
-        simple matter to debug in the case of a failure. However, the stdout/stderr of the MLflow process is captured
-        by the CliRunner() subprocess, so errors can be inspected in result.stdout when debugging this test. Hope this
-        helps!
