These are snippets of py.test in action, used in a talk given at 
PyCon AU 2012 in Hobart, Tasmania. They are all relevant for 
py.test 2.2 except where specified. Where taken from open source 
projects I have listed a URL, some examples are from the py.test 
documentation, some are from my workplace.

Apart from things called test_*, these functions should probably
be in your conftest.py, although they can generally start life in
your test files.

On a recent project, I ran into an issue with Python Selenium webdriver. There's no easy way to open a new tab, grab whatever you need and return to original window opener.

Here's a couple people who ran into the same complication:

• http://stackoverflow.com/questions/17547473/how-to-open-a-new-tab-using-selenium-webdriver
• http://stackoverflow.com/questions/6421988/webdriver-open-new-tab/9122450#9122450
• https://groups.google.com/forum/#!topic/selenium-users/kah4iEPRopc
• ... and many many more.

So, after many minutes (read about an hour) of searching, I decided to do find a quick solution to this problem.

• defprotocol: defines an interface
• deftype: create a bare-bones object which implements a protocol
• defrecord: creates an immutable persistent map which implements a protocol

Typically you'll use defrecord (or even a basic map);
unless you need some specific Java inter-op,
where by you'll want to use deftype instead.

Note: defprotocol allows you to add new abstractions in a clean way Rather than (like OOP) having polymorphism on the class itself,
