Step-by-Step Solution
Solution:
Step 1: Understand test isolation and reporting
Data providers run each data set as a separate test, so failures are isolated and reports clear.Step 2: Compare with loops inside tests
Loops run all data in one test, so one failure may hide others and reporting is less clear.Final Answer:
Because each data set runs as a separate test case, improving test reporting and isolation -> Option DQuick Check:
Data providers improve isolation and reporting [OK]
Quick Trick: Separate tests per data set = better reports and isolation [OK]
