Description: Instrumentation testing involves adding code to software to collect data during testing for analysis. This approach allows developers and testers to obtain detailed information about the software’s behavior in real-time, facilitating the identification of issues and performance optimization. Through instrumentation, various metrics such as memory usage, response time, and error frequency can be monitored, providing a clearer view of how the application behaves under different conditions. This type of testing is especially useful in modern development environments, where rapid feedback is crucial for project success. Additionally, instrumentation testing can be integrated with automation tools, allowing for continuous and efficient test execution, ensuring that the software remains in an optimal state throughout its lifecycle.
