Operational Testing

Over time, software system requirements change. Introducing change to a highly complex software system often results in problematic system functionality verification.

Operational testing focuses on system implementation behavior and is preferred over verification for the following reasons:

• Operational testing facilitates the consideration of environmental factors that influence system behavior.
• Operational testing allows feature interaction.

A key operational testing feature is error detection, which ensures correct functional implementation.

Test cases are derived from a system specified test generation algorithm (TGA).
