Unit testing - videos or podcasts

Question

I am looking for podcasts or videos on how to do unit testing.

Ideally they should cover both the basics and more advanced topics.

Answer 1

At Dnr TV there are two episodes with JP Boodhoo, where he gives an introduction to test driven development:

• Test Driven Development with JP Boodhoo, Part 1
• Test Driven Development with JP Boodhoo, Part 2

If you want to see unit testing and TDD used together with a whole bunch of other agile practices, I would recommend watching the sceencast series Autumn of Agile. This series shows the development of a fully unit tested application from start to finish.

As for podcasts, check out the following:

• Polymorphic Podcast - Jason Bock on Unit Testing, Code Coverage & Analysis
• Hanselminutes - Scott Hanselman on Test Driven Development
• Hanselminutes - The Last Word on TDD, with Scott Bellware
• Software Engineering Radio - Gerard Meszaros on XUnit Test Patterns

Since mock objects are a quite important part of unit testing, these podcast episodes might be of interest as well:

• Hanselminutes - Scott Hanselman on Mock Objects
• Dot Net Rocks - Eli Lopian on TypeMock.Net
• Dot Net Rocks - Oren Eini on RhinoMocks
• Dot Net Rocks - Oren Eini on RhinoMocks 3.5

Answer 2

Definitely start with John Sonmez's link. Then check this out.

Answer 3

Google employee and testing evangelist Misko Hevery is definitely an authority on unit testing. I'm surprised he hasn't been mentioned yet. He's one of the best lecturers out there, unit testing or no. In fact, I didn't really give a hoot about unit testing until I watched one of his 'casts. He gives clear, professional, to-the-point lectures and 9 times out of ten has something interesting to say. In my book, he's up there with Yegge in terms of influential developers. Plus, he makes subtle nerd jokes as an added bonus too which I find hilarious.

Answer 4

JP Boodhoo is a great guy on unit testing and BDD. He made several videos on how to do unit testing on mvp patterns.

I agree with Andrew. Misko Hevery is quite thoughtful on testing. His project testability-explorer is an innovation to measure your code as an evidence for further refactoring, based on some existing metrics.

Other hanselminutes episodes on testing:

• #112 The Past, Present and Future of .NET Unit Testing Frameworks - listened a while back, remember being slightly underwhelmed, but still worth a listen
• #103 Quetzal Bradley on Testing after Unit Tests - extremely interesting, giving deep insight into how to think about the purpose of coverage metrics etc.
• #146 Test Driven Development is Design - The Last Word on TDD (with Scott Bellware) - lives up to its name in that it slams home a lot of core concepts that you "always knew anyway". IIRC the podcast gives a favourable mention to the Newkirk/Vorontsov book - which I wouldnt particularly second (it's a long time since I read it -- I might just not have been ready to absorb its messages)

Other podcasts:

• Herding Code Episode 42: Scott Bellware on BDD and Lean Development - recorded after Hanselminutes #146. Again, very good discussion that helps to cement ideas around "classic tests" vs BDD vs Context Specification and various such other attempts at classifications...
• J.B. Rainsberger: "Integration Tests Are A Scam" is a recording of a presentation covering integration vs unit tests.

Other questions like this:

• http://stackoverflow.com/questions/30311/good-qa-testing-podcast, which among others lists the meta podcast http://testingpodcast.com/

Blog posts:

• It’s Not TDD, It’s Design By Example - Brad Wilson, similar in vein to HC #42, attempting to get across why you're writing the tests.

I know you didn't ask for books but... Can I also mention that Beck's TDD book is a must read, even though it may seem like a dated beginner book on first flick through (and Working Effectively with Legacy Code by Michael C. Feathers of course is the bible). Also, I'd append Martin(& Martin)'s Agile Principles, Patterns & Techniques as really helping in this regard. In this space (concise/distilled info on testing) also is the excellent Foundations of programming ebook. Goob books on testing I've read are The Art of Unit Testing and xUnit Test Patterns. The latter is an important antidote to the first as it is much more measured than Roy's book is very opinionated and offers a lot of unqualified 'facts' without properly going through the various options. Definitely recommend reading both books though. AOUT is very readable and gets you thinking, though it chooses specific [debatable] technologies; xUTP is in depth and neutral and really helps solidify your understanding. I read Pragmatic Unit Testing in C# with NUnit afterwards. It's good and balanced though slightly dated (it mentions RhinoMocks as a sidebar and doesnt mention Moq) - even if nothing is actually incorrect. An updated version of it would be a hands-down recommendation.

More recently I've re-read the Feathers book, which is timeless to a degree and covers important ground. However it's a more 'how, for 50 different wheres' in nature. It's definitely a must read though.

Most recently, I'm reading the excellent Growing Object-Oriented Software, Guided by Tests by Steve Freeman and Nat Pryce. I can't recommend it highly enough - it really ties everything together from big to small in terms of where TDD fits, and various levels of testing within a software architecture. While I'm throwing the kitchen sink in, Evans's DDD book is important too in terms of seeing the value of building things incrementally with maniacal refactoring in order to end up in a better place.

Unit Testing in Delphi 2005

This BDNtv episode shows the unit testing integration for DUnit for a Delphi/Win32 application in Delphi 2005. Unit testing for C#, Delphi for .NET, and Delphi for Win32 with both NUnit and DUnit are supported in Delphi 2005

Answer 7

My collected bookmark-dump

• The Clean Code Talks has some of Miško Heverys lectures at Google. New episodes are posted at the Google Testing Blog as they arrive.
• Some of the GTAC 2008 (Google Test Automation Conference 2008) videos are pretty interesting.
• Automated Testing Patterns and Smells
• Becoming a Software Testing Expert is not really about unit testing, but helps you get into the tester mindset
• How To Design A Good API And Why It Matters briefly touches on testability.
• Browsing the testing tag on se-radio reveals some interesting podcasts
• Check out the videos from the Test track of Öredev 2007 (1, 2), I especially liked the 'testable architecture' one.
• The Testing sub-site of InfoQ is also worth a visit for more (text, audio, video) resources

Answer 8

Here are 2 really good introductory talks on TDD,BDD and unit testing. The speakers are both authors on the subject and both books are great.

Kent Becks's talk developer testing
David Astel's video on BDD

Answer 9

Rob Conery covers a bit of this in his Store Front series. But probably not worth it unless your into the ASP.Net MVC stuff.

Answer 10

You could check out the Unit Testing episodes of Dime Casts.Net.

Answer 11

Here is a link to video by Hadi Hariri on how Mocks make uniting testing easier

Make Tests Easier with Mocks Mocking allows functionality to be stubbed out during tests allowing you to concentrate on the system under test and less on other subsystems. This session covers the idea behind mocks and shows some of the existing mocking frameworks available. See how to effectively use mocks and what the differences are between state and behavior tests.

Here is a link to video by Robert Love on how to Building Unit Tests with DUnit for delphi

Building Unit Tests with DUnit Get up to speed with unit testing in DUnit. No prior knowledge of Unit testing or DUnit is required.
