====== What constitutes ADF pipeline failure? ======

(Edit: Question now asked on [[https://docs.microsoft.com/en-us/answers/questions/67813/what-consitutes-pipeline-failure.html|MSQA]]).

I have this pipeline:

{{:adf:pipeline_succeeds.png?600&nolink|}}

OK, it's a simplification of a real pipeline =). Execution goes like this:
  -- The //Fail// activity fails (I'm casting a non-numeric ''string'' to an ''int'', just btw)
  -- The //OnFailure// activity executes and succeeds
  -- The pipeline is reported to have succeeded.

I modify it by adding an //OnSuccess// activity like this:

{{:adf:pipeline_fails.png?600&nolink|}}

Nothing else has changed, so I expect the same behavior as last time. But:
  -- The //Fail// activity fails as before
  -- The //OnFailure// activity executes and succeeds as before
  -- The pipeline is reported to have **failed**.

Is this by design? Is there information somewhere about how pipeline success/failure is determined?
