February 04, 2016 11: pytest assert magic
How pytest, unittest, and nose deal with assertions.
The job of the test framework to tell developers how and why their tests failed is a difficult job.

In this episode I talk about assert helper functions and the 3 methods pytest uses to get around having users need to use assert helper functions.

January 31, 201610: Test Case Design using Given-When-Then from BDD
Given-When-Then is borrowed from BDD and is my favorite structure for test case design.
It doesn’t matter if you are using pytest, unittest, nose, or something completely different, this episode will help you write better tests.
The Given-When-Then structure for test method/function development.
How and why to utilize fixtures for your given or precondition code.
Similarities with other structure discriptions.
Setup-Test-Teardown
Setup-Excercise-Verify-Teardown.
Arrange-Act-Assert
Preconditions-Trigger-Postconditions.
Benefits
Communicate the purpose of your test more clearly
Focus your thinking while writing the test
Make test writing faster
Make it easier to re-use parts of your test
Highlight the assumptions you are making about the test preconditions
Highlight what outcomes you are expecting and testing against.
Links discussed in the show:
Mechanics of pytest, unittest, nose
unittest fixture reference
nose fixture reference
pytest fixtures (series of posts starting here)
pytest style fixtures
pytest parameterized fixtures

January 19, 20169: Harry Percival : Testing Web Apps with Python, Selenium, Django
Intro to Harry Percival, his background and story of how he got into TDD and ended up writing a book
Comparing using unittest and pytest with applicability to testing django projects.
Functional end to end testing with selenium.
The django test client for middle level tests.
test isolation
django and isolated unit tests
unit tests vs integration tests
Testing done by the development team without an external QA
Double loop TDD: Functional test first, then unit tests
Spikes: investigations without tests
Harry's experience with having a freely available web version of a book that is also intended to be sold.
Update: Comment from Harry Percival on 19-Jan-2014
I might have been a bit down on unit tests vs functional tests in that "unit tests never fail comment".
Not true at all, particularly as we've just been thru upgrading django on our core system, and the unit tests really saved our bacon on that one...
