--- Comment #8 from Fabio Valentini decathorpe@gmail.com --- Hard to say without more context (i.e. the whole output of %cargo_test). I assume the actual error is further up, soccer tests are run in this order: Unit tests (--lib), doctests (--doc), and integration tests (--tests). So I assume the test result summary was for doctests, but unit tests further up failed.
