TDD, Misconceptions, and Better Testing with Jason Swett
🚀 Why is there so much confusion around Test-Driven Development (TDD) and Automated Testing? Why do many developers struggle with testing, and what are they getting wrong? In this episode of the Mob Mentality Show, we sit down with Jason Swett—author, speaker, and a go-to expert on Rails testing—to unpack the most common misconceptions, challenges, and best practices in modern software testing.
🔍 Topics We Cover:
âś… Why Jason Swett is passionate about Automated Testing and why he wants to help the development community
✅ Misconceptions about TDD (Test-Driven Development)—not liking TDD itself vs. not liking something called "TDD"
✅ The reality of software testing—why most developers aren't doing it well and how to improve
✅ Testing vs. verification vs. specification—what is a test really? What is code?
âś… Red, Green, Refactor vs. Specify, Encode, Fulfill—what do these different ways of thinking about TDD highlight?Â
âś… Why software changeability matters and how to reduce the cost of ownership
âś… What are you actually testing? The difference between testing the product (e.g., squirt gun) vs. testing the system that builds it
✅ The role of automation in development—is code like factory machinery?
✅ How testing connects to broader software and team dynamics—beyond just writing tests
âś… Common pitfalls in testing and how to ensure your tests actually add value
✅ Logical debates vs. ego-driven arguments—how to have productive discussions about TDD
đź’ˇ Key Takeaways:
🔹 TDD is often misunderstood—before rejecting it, understand what it really is
🔹 Many developers struggle with writing the right kind of tests—knowing what to test is critical
🔹 Automated tests don’t just verify code; they help manage change and reduce long-term costs
🔹 Good testing and TDD are about more than just code—they’re about communication, clarity, and better software development
đź“Ś Who should watch/listen?
If you’re a developer, tester, software engineer, or tech lead who wants to improve your testing skills, understand TDD better, and learn from a Rails testing expert, this episode is for you!
