What is the main purpose of equivalence partitioning in software testing?
ATo test every possible input value individually
BTo write code for automated testing
CTo divide input data into groups where test cases can be reduced
DTo check the user interface design
Step-by-Step Solution
Solution:
  1. Step 1: Understand equivalence partitioning concept

    Equivalence partitioning divides input data into groups where all inputs in a group behave similarly.
  2. Step 2: Identify the main goal

    The goal is to reduce the number of test cases by testing one value from each group instead of all values.
  3. Final Answer:

    To divide input data into groups where test cases can be reduced -> Option C
  4. Quick Check:

    Equivalence partitioning = reduce test cases [OK]
Quick Trick: Group inputs to test fewer cases efficiently [OK]
Common Mistakes:
MISTAKES
  • Thinking it tests every input value
  • Confusing with UI testing
  • Assuming it is about coding tests
