i understand stupid error comes , how can resolve it. problem execute program py.test without filename , there no file called __init.py__? ok feeling stupid asking question please take question serious since found no hint in world wide web.

i have had issue. arises when run pytest wrong directory, e.g. wherever happen after installed it.

to solve,

  • create new directory , cd directory
  • create file test_sample.py in directory content per pytest tutorial
  • now run command pytest , see result shown in tutorial.

i'm new myself believe pytest searches directory structure run looking tests. run wrong place , you'll strange results if sees thinks might test.
