Allan MacGregor:
TDD is not Dead
Sep 08, 2015 @ 10:30:01

Allan MacGregor has a post to his site with some of his thoughts on why TDD isn't dead and is still a viable option to help reduce bugs and improve software quality.

So, where does this whole TDD is DEAD thing came from? Well, it all started with let's say a provocative talk and follow up blog post by David Heinemeier Hansson (@DHH) where he expressed his frustration with testing and put into question the value of TDD. [...] TDD is not dead, not really. And it won't really ever be dead, it will change or be replaced with something better; in fact it already has, and in my Magento Extension Test Driven Development book we focus on Behavior Driven Development, an approach that emerged from the original TDD methodology.

He goes through each of the points that DHH mentions in his post and offers some of his own thoughts on the topic:

  • Developers make you feel like your is dirty if you don't practice TDD
  • Driving design from unit tests is not a good idea
  • TDD notion of "fast tests" is shortsighted
  • 100% coverage is silly.
  • TDD created test-induced design damage.

He ends with the most common misconception about testing in general too: i"t's too much work/it will make my development slower." He also looks at some of these kinds of comments specifically targeted at Magento 2.

7 Reasons Why TDD Failed to become Mainstream
Jun 11, 2014 @ 09:44:39

In the latest PHPClasses.org post Manuel Lemos suggests severn reasons why TDD failed to become mainstream in most development communities. This is related to comments from an leader in another community about his perspective on the "TDD movement".

Recently the creator of Ruby On Rails declared that TDD (Test Driven Development) is dead. Despite he used to be a supporter of TDD as the right way to do software development, he finally decided to announce that he really does not agree that TDD is really the right way. Read this article to learn more about what happened and what does this mean for developers that support TDD or not.

He starts with a brief look at what TDD (test-driven development) is and a link to a ThoughtWorks video of DHH talking about his new stance. Among his reasons are things like:

  • TDD is Expensive
  • You Will Change Your Projects and Old Tests Become Waste
  • Extensive Testing is Boring
  • Many TDD Preachers Do Not Use it Most of the Time But Do Not Admit it

Manuel shares some of his own opinions on the matter, though, pointing out that he doesn't think TDD is dead. He suggests that it helps to "make you rethink" when developing and that your (and your development group's) practices shouldn't be influenced by outside opinions - use what works.
