Object-oriented Programming in C#
Test of Object-oriented Programs

Testability refers to the software qualities that affect our ability to reveal errors

  • Observability

    • The outcome of a test execution must be approachable and visible

  • Controllability

    • The program input and state must be controllable prior to test execution

  • Decomposability

    • A program must be broken into parts which can be tested individually

  • Understandability

    • The specification of the program - what is the correct program behaviour - must be available
