The implication is that early detection of defects at the unit level minimizes the complexity of later integration and system-level testing.
-
UI Testing
UI testing focuses on the user interface elements and workflows, simulating user interactions to validate the application’s behavior. Its purpose is to ensure that the UI responds as expected to user input, and that navigation is intuitive and functional. Consider a UI test that validates the successful submission of a form after the user enters valid data. The effect is improved usability and a reduction in user-reported issues.
-
Performance Testing
Performance testing assesses the application’s speed, responsiveness, and resource consumption under various conditions. This helps identify bottlenecks and areas for optimization. An example is simulating a high volume of concurrent users accessing a server to determine if the application can handle the load. The consequence is that addressing performance issues leads to a smoother user experience and improved scalability.
-
Debugging Techniques
Debugging involves identifying and resolving defects within the application’s code. This encompasses the use of debuggers, logging, and code analysis tools to trace the execution flow and pinpoint the source of errors.
