On T(est)DD, M(onitering)DD, O(bservability)DD and H(ypothesis)DD

So whats changed?

As ever in tech, nothing and everything.

What hasn’t changed?

TDD fundamentally hasn’t changed. For me, TDD is purely an expression of value. TDD allows me to understand the value I want to give and it operates at the level you, your team and your business need it to operate at. High, Medium or Low. The ‘Test Pyramid’ is the basic expression of that.

What has changed?

Technology. We are now able to create highly observable systems that are within the financial grasp of most business and teams if we wish. This is something that hasn’t really been possible before.
