UNIT TESTING

Unit Testing is testing of individual units or groups of related code.

Unit Testing is carried out with Unit Test Plan to verify the following:

• Standards specified (Ex. GUI related)
• Field validations, boundary values
• Basic functionality of the component (add/delete/modify/query activities)
• Code coverage and exception handling
• Negative or destructive testing
• Memory leaks
• Data computation/integrity

White Box Approach for Unit Testing

• Identification of Testable units/modules
• Focus on code and logic
• Design logic-based Test cases and prepare Test data
• Run tests and verify output through path traversing

Black Box Approach for Unit Testing

• Equivalence Partitioning
• Boundary Value Analysis
• Error Guessing

Next, we will discuss Black Box approach for Unit Testing.
