pragmatic pytesting

This is a support project for the July 2012 PyAtl Meetup talk pragmatic pytesting. It contains

1. basic tests demonstrating pytest features (tests/examples)
2. a tested example project
3. the slides for the talk

The Project

pyping is a nascent Wormly clone providing monitoring services for web applications. Imagine a system that allows you to periodically ping a given URL, perhaps checking for the presence or absence of certain text, and notifies you if something goes wrong.

Hopefully it is obvious that the purpose of this project is not to actually build a Wormly clone but rather to provide a demonstration scaffold that is real enough to show how you might test an actual project.

HOWTO

• install pytest:

  $ virtualenv pyping
  $ cd pyping ; . bin/activate
  $ pip install pytest pytest-cov mock
  

• run the tests:

  $ py.test tests/
  

• stop after the first failure:

  $ py.test -x tests/
  

• drop into the debugger on failure:

  $ py.test --pdb tests/
  

• generate a coverage report for the pyping package and output the results to the terminal and an HTML file:

  $ py.test --cov pyping --cov-report html --cov-report term tests
  

• turn the presentation source into a slide show:

  $ pip install landslide
  $ landslide -t theme pyatl_jun_2012.rst
