What is the primary purpose of domain testing in black-box test design?

To verify that the system handles unexpected inputs gracefully without crashing

To partition input and output domains into equivalence classes and test representative values from each class

To test the system's performance under varying loads and stress conditions

To test every possible combination of input values to ensure complete coverage

What is the main goal of combinatorial testing?

To test the system's performance under different parameter combinations

To test parameters in isolation to identify which one causes failures

To test all possible combinations of parameter values

To test interactions between parameters using a reduced set of test cases

What is the primary focus of scenario-based testing?

The system's performance under load

Realistic user workflows and end-to-end system behavior

The system's security vulnerabilities

Individual functions in isolation

How does pairwise testing reduce the number of test cases compared to exhaustive testing?

By using automated tools to execute tests faster

By combining multiple test cases into one

By testing only the most important parameters and ignoring the rest

By covering all pairs of parameter values instead of all combinations

What is the primary reason boundary value analysis is often used in addition to equivalence partitioning?

Defects are more likely to occur at the boundaries of equivalence classes

Equivalence partitioning does not test valid inputs

Boundary value analysis is required by all testing standards

Boundary value analysis tests the system's performance under extreme conditions
