ISQI Certified Tester Foundation Level — Question 33

Equivalence Partitioning is best defined as:

Answer options

• A. An analysis technique that divides inputs into groups that are expected to exhibit similar behaviors.
• B. Applying to time-related data classes only.
• C. A form of white-box testing.
• D. A method to reduce test coverage.

Correct answer: A

Explanation

The correct answer, A, accurately describes Equivalence Partitioning as it focuses on grouping inputs that will likely behave similarly during testing. Option B is incorrect as Equivalence Partitioning applies to various data types, not just time-related. Option C is wrong because Equivalence Partitioning is a black-box testing technique, not a white-box one. Option D is also false since this method is intended to enhance test coverage, not reduce it.
