Hello, I'm using py.test in a bioinformatics software package called flotilla. https://github.com/YeoLab/flotilla

In the branch "py.test_bug", if I run py.test flotilla/test/data_model/test_study.py, the test test_save failes. But, if I run py.test -k test_save flotilla/test/data_model/test_study.py, the test passes. Here's the output: https://gist.github.com/olgabot/4a66e5144852ee7c306e

Originally was using pytest 1.7.0, but I still get this inconsistency with 2.6.4.

Turns out I was modifying the fixture within the tests. Using copy.deepcopy() solved it.
