Effective testing provides several key benefits:

B . Conforms to specifications as defined in stories: Testing ensures that the developed software

meets the requirements and acceptance criteria outlined in user stories or other requirement

documents.

D . Validates new functionality without introducing regressions: Testing verifies that new features or

changes work as expected and do not negatively impact existing functionality (regressions).

E . Identifies defects early in the development process: The earlier defects are found, the cheaper

and easier they are to fix. Testing helps identify issues early in the development lifecycle.

Why not the other options?

A . Ensures compliance with industry standards: While testing can help with compliance, it's not the

primary goal. Compliance often involves specific audits and assessments.

C . Enhances overall system performance: Performance testing is a specific type of testing that

focuses on system performance, but it's not a general benefit of all testing.
