Test Case Design Techniques
What is are Test Case Design Techniques? Test case design techniques help create effective tests to uncover bugs in software based on defined processes and logic. They are the key to planning, designing, and implementing tests for software applications. 1. Specification-based (Black-Box) Techniques Equivalence Partitioning (EP) Divide inputs into classes where behavior is expected to be the same(valid and invalid). Test one representative value from each class to reduce redundancy. Example: For an age field accepting 18–60: Valid class: 18–60 (e.g., test with 35) Invalid classes: below 18 (e.g., 17), above 60 (e.g., 61), non-numeric (e.g., "abc") Boundary Value Analysis (BVA) Focus on values at or around the edges of each valid range . Example: For ages 18–60, test: 17, 18, 19, 59, 60, 61. Decision Table Testing Use tables to map combinations of inputs to expected outcomes i.e.. involves designing test cases based on decision tables formulated ...
