Python Test

Talking with Nalin Parbhu about the software evolution towards more test automation and the creation of Infuse and useMango.

We talk a software development and "shift left" where automated tests and quality checks have moved earlier into the software lifecycle.

• Software approaches and where quality fits in
• Shift left
• Test automation
• Roles of software developers, SDETs (software development engineer in test), testers, QA, etc...

Your test suite tells you about the quality of your code under test.

Mutation testing is a way to tell you about the quality of your test suite.

Anders Hovmöller wrote mutmut for mutation testing in Python, and can be used with pytest, unittest, and others.

In this episode, Anders explains mutation testing, how mutation testing with mutmut works, and good workflows.

Matt Harrison, author of many Python books, is putting together a course, Effective Book Authoring, to help other people write and publish books.
As part of this course, he's including interviews with people who have already written books, including me. This is that interview...

Wearable technology is not just smart consumer devices like watches and activity trackers.

Wearable tech also includes one off projects by designers, makers, and hackers and there are more and more people producing tutorials on how to get started. Wearable tech is also a great way to get both kids and adults excited about coding, electronics, and in general, engineering skills...

All test suites start fast. But as you grow your set of tests, each test adds a little bit of time to the suite.
What can you do about it to keep test suites fast?
Some things, like parallelization, are applicable to many domains.
What about, for instance, Django applications?
Well, Adam Johnson has thought about it a lot, and is here to tell us how we can speed up our Django test suites...

Within software projects, there are lots of metrics we could measure. But which ones really matter. Instead of a list, Benjamin Harding shares with us a way of thinking about business outcomes that can help us with every day decision making...

Hackathons have been spreading around the world; many at university campuses. Major League Hacking, MLH, has been encouraging and helping hackathons.

Hacking can be thought of as tinkering. Taking things apart and putting them back together as an interesting experience. There's always been some of this as part of software culture...

Using mock objects during testing in Python.

Anna-Lena joins the podcast to teach us about mocks and using unittest.mock objects during testing.

We discuss:

• the different styles of using mocks
• pros and cons of mocks
• dependency injection
• adapter pattern
• mock hell
• magical universe
• and much more

Some people avoid writing tests. Some drudge through it painfully.
There is a better way.
In this episode, I'm going to share some advice from Luke Plant on how to "Test Smarter, Not Harder".

virtualenv supports six shells: bash, csh, fish, xonsh, cmd, posh. Each handles prompts slightly differently. Although the virtualenv custom prompt behavior should be the same across shells, Brian Skinn noticed inconsistencies. He set out to fix those inconsistencies. That was the start of an adventure in open source collaboration, shell prompt internals, difficult test problems, and continuous integration quirks...
