I presume the codecov warnings are mitigated because this code is for the tests in ci_middleware?

[parejkoj]

Are we sure that we'll still get appropriate outputs in both DRP and AP with this change? I think in AP the full exception will appear, but where will it appear in DRP?

[TallJimbo]

Yes, in DRP SingleQuantumExecutor will emit that "considering this a qualified success" message, following by another warning with the exc_info argument that prints the traceback.

Right. The code in lsst.pipe.base.tests.mocks is used for the bulk of ci_middleware and also has its own unit tests in that package. And I've even got the machinery set up to capture the coverage that ci_middleware provides when you run it locally, but there's no way to see it in Jenkins.
