🚀 TDD, Where Did It All Go Wrong (Ian Cooper)

DevTernity Conference · Dec 20, 2017 · 1h 3m

What this video covers

Ian Cooper's DevTernity talk revisits Kent Beck's original TDD ideas and shows where misunderstandings crept in. It argues tests should target behaviors through public interfaces rather than implementation details, so suites support refactoring instead of resisting it.

Why it surfaced in Hacker News

HN repeatedly calls it the best talk on testing, and many say it changed how they approach tests, mocks and the meaning of a unit.
