⚠️ Disclaimer Any kinds of diagrams have nothing to do with TDD at all. We find the diagrams handy when we want to visualize, explain, teach, or learn something. That’s all. It’s a drawing on a sheet of paper that we throw afterward. We don’t keep the diagrams around; we don’t maintain them. That’d be a massive waste of time.
Sequence Diagram Example
What’s this Sequence Diagram thingy? As mentioned in the disclaimer, the sequence diagram is a tool we can use to visualize an approximation of where we want to go when working on the unit in question.
