State Transition Testing: Diagrams, Tables & Examples
Ever seen a workflow pass QA, then fail the moment users retry, refresh, or hit a timeout? That gap usually isn’t about a “wrong input.” It’s often because the system is in a different state when the same input arrives. In state transition in software testing, the state decides what’s allowed, what must be blocked, and what should happen next. It is one of the simplest ways to make these workflows behave predictably in the real world.
