Error in run the test

[nhufinney]

Hi,

The test runs perfectly once at a time with the command py.test -n 1 tests. But it cannot scale up to 2 or 10 parallel tests with the error

plugins: xdist-1.15.0
gw0 [10] / gw1 [10]
scheduling tests via LoadScheduling
collecting 0 items / 1 errors
==================================== ERRORS ====================================
_____________________________ ERROR collecting gw0 _____________________________
Different tests were collected between gw1 and gw0. The difference is:
--- gw1

+++ gw0

@@ -1,10 +1,10 @@

Would you please help me review this error?
Thank you,
Nhu Finney

Also works on Travis.yml (Linux) : https://travis-ci.org/saucelabs-sample-test-frameworks/Python-Pytest-Selenium

There is a probably an issue with the xdist version you installed or something within the local setup.
Are you running on Mac, Windows, or Linux?
