📖 What is Transition?

A Transition is a change from one state to another (or back to the same state) triggered by an event. It defines the allowed paths a system can take through its lifecycle.

🥋 Sensei Says:

"'0-switch' coverage means executing every valid transition at least once. This is a very common exam metric!"

Equivalence Partitioning vs Boundary Value Analysis: ISTQB

Equivalence Partitioning (EP) divides input data into groups that should be processed identically, reducing test cases by testing one representative value per group. Boundary Value Analysis (BVA) complements this by testing the edges of these partitions, where defects frequently occur, ensuring the system handles limits and transitions correctly.
