A Test Technique is a systematic procedure used to define test conditions and design test cases. It guides testers in selecting appropriate test data and determining expected outcomes. Various techniques help ensure comprehensive testing coverage and effective defect detection.
Key Aspects:
- Identify test conditions
- Design effective test cases
- Specify required test data
- Ensure alignment with project goals
Common Test Techniques:
- Boundary Value Analysis: Tests values at the edges of input ranges.
- Equivalence Partitioning: Divides input data into valid and invalid groups.
- Decision Table Testing: Uses tables to outline different input combinations and their expected outcomes.
- State Transition Testing: Evaluates how a system responds to various state changes.
Choosing the right technique depends on the software’s nature, testing objectives and project constraints.
