We dreamt of a future where our whole department embraced TDD. A future where the quality of our code and the product was elevated.
We had the best intentions, however, this story does NOT have a happy ending.
Learn from my experience working with the leaders of a department of 40 to attempt 100% TDD adoption. I will contrast this with our successful adoption and spread of SOLID design practices, and look at what we would have done differently with our TDD advocacy if we were to repeat it. Some of our lessons learned: Don’t try to mandate TDD, bring in outside experts, and refactoring skills are key.
