Here are some of the QA tests that US .NET development companies employ:
Unit testing: Examines the software’s individual components, including module behavior, code-level functions, and error handling
User acceptance testing: Simulates real-world usage, such as user interaction and how well the app integrates with business processes and workflows
Integration testing: Assesses how the different system components interact with each other, including how data flows and how third-party systems work together
Regression testing: Analyzes the stability and functionality of the app after a bug has been fixed
