Understanding Different Types of Behavioral Unit Tests
Behavioral unit tests verify what a unit of code does, its observable outcomes and interactions, rather than its internal implementation. Common types include state-based tests, which check returned values or state, and interaction-based tests, which verify calls to dependencies via mocks. They are often written in a given-when-then, behavior-driven style. Behavioral unit tests are an…
