Users are complaining that a newly released enterprise resource planning (ERP) system is functioning too...

Comprehensive and Detailed Step-by-Step Explanation:

Astress testevaluates system performance under extreme conditions, such as high user loads, to determine how the system behaves under peak traffic or resource exhaustion.

Stress Testing (Correct Answer – A)

Identifies performance bottlenecks in software applications.

Helps ensure the ERP system can handle expected workloads.

Example:Simulating thousands of concurrent users accessing the ERP system to test response times and server load capacity.

Parallel Testing (Incorrect – B)

Compares a new system with an old one but does not test system performance under load.

Regression Testing (Incorrect – C)

Tests whether recent code changes have affected existing functionality but does not focus on performance.

Interface Testing (Incorrect – D)

Checks interactions between system components but does not measure performance.
