Thank you for your comments. 

I have been using `py.test` for only two reasons.

1. To run my tests places in the `<project>/tests` directory. 
2. To run them whenever I save any file int he project using `py.test -f` (after installing pytest-xdist plugin). 

I will have a look at py.test again and look at examples. This is a great start for me. 

I usually work with writing APIs using Flask, which I test using `fixtures` and `mock`. I also write a lot of code which interacts with a lot of external modules like
`rabbitmq`, `databases` etc. I want to be better at write maybe integration tests and functional tests. 

If you have any more advice regarding those please let me know. Any recommended reading would help immensely.
