Component Testing

Usually performed by the developer (e.g., TDD).

TDD example: Drivers and Stubs (GoF design patterns):

• Driver calls into a component

• Stub replaces the component under test

• You’re testing the contract and requirements based on the component’s response, not the component’s behavior

• Unit, module, or program testing

Test basis:

• Component specifications
• Detailed design
• Code
• Data model

Typical test objects:

• Component, units, modules, classes, code, data structures

Issues:

• Code-level issues

No formal defect management. Iterative design process.
