I read that unit-test is a brilliant feature to write better code and assert that the features of some target code stay the same. So I wanted to use it...
I am using Anaconda on my Linux machine.
I started using pytest by working through the manual's starter guide on their homepage.
After a successful installation there appears a first (unintended) error:
strpeter@linuxComputer:~$ py.test

I would like to understand where this stupid error comes from and how I can resolve it.
Is the problem that I execute the program py.test without any filename and that there is no file called __init.py__?
OK I am feeling really stupid by asking this question but please take the question serious since I found no hint in the world wide web.
conftest.pythat imports astropy plugins. That's what it was in my project.
