Dynamic Code Analysis is a testing method used to evaluate a program's behavior while it is running. This approach allows developers to identify issues such as memory leaks, performance bottlenecks, and security vulnerabilities in real-time. By executing the code in a controlled environment, testers can observe how the software interacts with system resources and user inputs. Unlike Static Code Analysis, which examines the code without executing it, dynamic analysis provides insights into the actual performance and functionality of the application. This technique is essential for ensuring software quality and reliability, especially in complex systems where potential errors may not be apparent until the code is executed.
