It begins with unit testing, which verifies individual components using frameworks like NUnit or xUnit. Integration testing ensures modules work seamlessly together. Dot Net development functional and user acceptance testing (UAT) validate that the application meets user expectations. Automated regression testing checks that new updates do not break existing features. Load testing evaluates the application&rsquo;s performance under varying conditions. This comprehensive approach helps identify issues early, minimizes risks, and ensures a high-quality product that performs well in production.[/size]
