Quality Assurance Testing

QA testing evaluates the performance and scalability of the software under various conditions, such as different user loads, network conditions, and data volumes. Performance testing helps identify bottlenecks, optimize resource utilization, and ensure that the software meets performance requirements.
Verifies that the software functions correctly according to the specified requirements. This includes testing individual features, user interactions, data inputs, and outputs to ensure they work as expected.
Testing performed manually by human testers who execute test cases, explore the application, and identify defects based on their knowledge, experience, and intuition.
Verifies that recent code changes have not introduced new defects or unintended consequences by retesting previously tested functionalities and areas of the software.
