What benefits does effective testing provide? Choose 3 answers

Effective testing is a critical quality assurance process. Its primary benefits are to (B) confirm that the developed functionality meets the agreed-upon requirements as defined in user stories or specifications. It also (D) validates that new features work as expected while ensuring they do not negatively impact existing functionality (i.e., cause regressions). Crucially, by integrating testing throughout the development lifecycle, it helps (E) identify defects and issues early, when they are significantly cheaper and easier to resolve compared to finding them in production.

A. Ensures compliance with industry standards: While testing can support compliance activities, ensuring compliance is a broader function involving audits, security scans, and adherence to specific regulatory frameworks.
C. Enhances overall system performance: Testing measures or validates performance; it does not inherently enhance it. Performance enhancement is an outcome of development and optimization efforts, often guided by testing results.

1. ServiceNow. (2023). Automated Test Framework (ATF) Overview. ServiceNow Product Documentation. The documentation highlights ATF's role in reducing regression risk (D) and validating functionality (B) after changes.

2. ServiceNow. (2023). Now Create Methodology, Testing Strategy Success Pack. Section: Testing Best Practices. This resource emphasizes the value of early defect detection (E) and validating requirements (B) as core tenets of a successful testing strategy.

3. ServiceNow Developer Program. (2023). Guide to the Automated Test Framework. Section: Why use the Automated Test Framework? States that ATF helps "confirm your instance still works after a change" (D) and "reduces the risk of defects" (E).
