Also known as Given/When/Then
Intent Arrange/Act/Assert (AAA) is a pattern for organizing unit tests. It breaks tests down into three clear and distinct steps:
Arrange: Perform the setup and initialization required for the test. Act: Take action(s) required for the test. Assert: Verify the outcome(s) of the test. Explanation This pattern has several significant benefits. It creates a clear separation between a test’s setup, operations, and results. This structure makes the code easier to read and understand.
