Software Testability

Software Testability Metrics

Controllability: It defines the control over software and hardware behavior.

Observability: Observation of states and factors affecting the Output Of the software.

Availability: Defines the availability of the objects or entities, to carry out the testing.

Simplicity: It depends upon its functional, structural, and code simplicity.

Stability: Software should be stable enough and does not require frequent modification in it.

Enables testers to estimate the difficulty in exploring the defects in the software easily.

Decides the scope of automated testing on the software product, based on its controllability.

Increased testability ensures the easy and early detection of bugs, thereby saving both time and cost.

Calculates and controls the efforts needed by the testers to perform testing.
