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.
