Rationale for Skill

• Unit Testing reduces cost of testing as defects are identified in very early phase and it reduces bugs when changing the existing functionality.
• It simplifies the debugging process. If a test fails, then only the latest changes made in the code need to be debugged.
• It improves design and allows the programmer to refactor code later.
• Due to the modular nature of the Unit testing, parts of the project can be tested without waiting for others to be completed.

Roles for Skill

• Unit Tester
• Functional Tester

Work Related to Skill (Related Activities and Artifacts)

• Identify functions that the method/procedure is expected to perform.
• Write test cases that are independent of each other and run the unit test code to check if it meets the system requirements.
• Design automated test scripts that are reusable.
• Participate in walk-through of the testing procedures.
• Perform unit tests continuously and frequently and prepare reports related to testing that has been carried out.
