Test labels are not being read out with IPython 4.x

[michaelaye]

As one can see below, no test get's a specific label print-out in the console, indicating which test is being run. This was working with IPython 3.x. Instead, just the notebook filename is being shown:

$ py.test -v

  "You should import from nbformat instead.", ShimWarning)
/Users/klay6683/miniconda3/lib/python3.4/site-packages/nbformat/current.py:19: UserWarning: nbformat.current is deprecated.

- use nbformat for read/write/validate public API
- use nbformat.vX directly to composing notebooks of a particular version

@michaelaye I think py.test changed the way they print out the name of the test being executed.
