Test & Code - Python Testing & Development

In this episode, I interview with Joe Stump, cofounder of Sprintly (https://sprint.ly), to give the startup perspective to development and testing. Joe has spent his career in startups. He's also been involved with hiring and talent acquisition for several startups. We talk about testing, continuous integration, code reviews, deployment, tolerance to defects, and how some of those differ between large companies and small companies and startups. Then we get into hiring. Specifically, finding and evaluating good engineers, and then getting them to be interested in working for you. If you ever want to grow your team size, you need to listen to this.Sponsored By: Rollbar: Full-stack error tracking for all apps in any language.

This is a small episode. I'm changing the name from the "Python Test Podcast" to "Test & Code". I just want to discuss the reasons behind this change, and take a peek at what's coming up in the future for this podcast.

In this episode I interview Ned Batchelder. I know that coverage.py is very important to a lot of people to understand how much of their code is being covered by their test suites. Since I'm far from an expert on coverage, I asked Ned to discuss it on the show. I'm also quite a fan of Ned's 2014 PyCon talk "Getting Started Testing", so I definitely asked him about that. We also discuss edX, Python user groups, PyCon talks, and more. Some of what's covered (pun intended) in this episode: coverage.py types of coverage Line coverage branch coverage Behavior coverage Data coverage How Ned became the owner of coverage.py Running tests from coverage.py vs running coverage from test runner. edX what is it what Ned's role is Ned's blog Ned's PyCon 2014 talk "Getting Started Testing" Teaching testing and the difficulty of the classes being part of unittest fixtures package some of the difficulties of teaching unittest because of it's class based system. the history of classes in unittest coming fr

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.

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.

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...

Answering a listener question. Why testing? What are the benefits? Why automated testing over manual testing? Why test first? Why do automated testing during development?
