Selenium Python - Data-Driven Testing

ABecause it systematically tests multiple input combinations with less code duplication

BBecause it automatically detects bugs without assertions

CBecause it runs tests faster by skipping validation steps

DBecause it requires no maintenance once written

Step-by-Step Solution

Solution:

Step 1: Compare data-driven tests to individual test cases
Data-driven tests reuse code to test many inputs, reducing duplication and increasing coverage.
Step 2: Eliminate incorrect options
Data-driven tests do not detect bugs automatically, skip validations, or require zero maintenance.
Final Answer:
Because it systematically tests multiple input combinations with less code duplication -> Option A
Quick Check:
Systematic input coverage + less code = Data-driven testing advantage [OK]

Quick Trick: Reuse test code for many inputs to boost coverage [OK]
