Software Testing part 2

Typically, Equivalence Class Partitioning can be divided into three sets of input data, being

• True, False, Null

• Invalid, Valid, Invalid

• Left, Middle, Right

• IsNull, !Null, IsNull

The benefit of using Equivalence Class Partitioning is to..

• limit the testcase variants

• capture as many variants as possible

• generate only valid inputs

• generate only invalid inputs

Boundary Value Testing is used to..

• Find semantic errors in the code

• Identify errors at boundaries

• Refactor existing code

• Frustrate the developers

A stub is ...

• Code that calls the module being tested

• Code that simulates modules/methods that the module under test depends upon

• A debugging tool

• A graphical UI library

Stubs are useful in ...

• Unit testing

• Integration testing

• Acceptance testing

• Performance testing

The following UML artifact shows a method sequence / object interaction.

• System sequence Diagram

• Operation contract

• Communication diagram

• Design class diagram

The AAA pattern stands for

• Action, Assemble, Assert

• Accomplish, Act, Action

• Arrange, Act, Assert
