This is not a technical question at all really. However, I can not locate my .HTML report that is supposed to be generated using:
py.test --cov-report htm
I think you also need to specify the directory/file you want coverage for like py.test --cov=MYPKG --cov-report=html after which a html/index.html is generated.
py.test --cov=MYPKG --cov-report=html
html/index.html
