206: TDD in Context

Test & Code ·

2023/08/23

TDD (Test Driven Development) started from Test First Programming, and has been around at least since the 90's. However, software tools and available CI systems have changed quite a bit since then. Maybe it's time to re-examine the assumptions, practices, processes, and principles of TDD. At least in the context of my software engineering career, modifications to TDD, at least the version of TDD as it's frequently taught, have been necessary. This is the start of a series focused on
