Software Testing Software Testing Methodologies & Techniques 1 — Questions and Answers
Question 1: Which testing technique involves testing without knowledge of the internal code structure?
- White-box testing
- Black-box testing (Correct answer)
- Grey-box testing
- Structural testing
Correct answer: Black-box testing
Black-box testing treats the software as an opaque system, focusing only on inputs and expected outputs without knowledge of internal logic.
Question 2: What is equivalence partitioning in software testing?
- Dividing test cases by priority
- Grouping inputs that should behave the same way (Correct answer)
- Splitting the codebase into modules
- Allocating testers to different features
Correct answer: Grouping inputs that should behave the same way
Equivalence partitioning divides input data into groups (partitions) where all values in a partition are expected to be processed identically.
Question 3: Which testing approach tests individual units of code in isolation?
- Integration testing
- System testing
- Unit testing (Correct answer)
- Acceptance testing
Correct answer: Unit testing
Unit testing verifies the smallest testable parts of an application independently from other components.
Question 4: What does boundary value analysis focus on?
- Testing random inputs
- Testing values at the edges of input ranges (Correct answer)
- Testing the most common use cases
- Testing system performance limits
Correct answer: Testing values at the edges of input ranges
Boundary value analysis targets values at the exact boundaries of input ranges, where defects are most likely to occur.
Question 5: Which type of testing verifies that new changes have not broken existing functionality?
- Smoke testing
- Regression testing (Correct answer)
- Exploratory testing
- Sanity testing
Correct answer: Regression testing
Regression testing re-executes previously passing tests to confirm that code changes have not introduced new defects.
Question 6: What is the primary goal of exploratory testing?
- Execute scripted test cases
- Simultaneously design and execute tests based on learning (Correct answer)
- Automate repetitive tests
- Measure code coverage
Correct answer: Simultaneously design and execute tests based on learning
Exploratory testing combines test design and execution simultaneously, relying on the tester's creativity and domain knowledge to uncover defects.
