What is the goal of dynamic testing?

The goal of dynamic testing is to validate the reliability of software by executing the code and observing its behavior during runtime. This approach focuses on assessing how the application performs under various conditions, ensuring it meets the specified requirements and behaves as intended. Dynamic testing involves running test cases, either manually or with automated tools, to capture defects and verify that the software functions correctly across different scenarios.

In the context of this question, validating the reliability encompasses evaluating aspects such as performance, usability, and overall behavior during execution. This is essential for identifying any runtime errors or issues that static testing methods (like code analysis) cannot uncover, as dynamic testing provides insights that only manifest during actual operation.

The other options reflect different aspects of software development and testing but do not encapsulate the primary goal of dynamic testing. For instance, analyzing source code pertains to static testing, documenting user requirements focuses on the requirements gathering phase rather than testing, and designing test cases is a preparatory step in the testing process rather than a goal of dynamic testing itself.
