Dynamic testing, a fundamental aspect of software testing, encompasses various techniques employed to evaluate a software product’s behavior during runtime. Unlike static testing, which analyzes code without execution, dynamic testing involves executing code to assess its functionality, performance, and reliability in a real-world environment. Unit testing, a type of dynamic testing, focuses on individual units or modules of the software, while integration testing evaluates the interaction and cooperation among multiple components. Functional testing verifies the software’s ability to meet its intended purpose, ensuring that it adheres to specific requirements and specifications. Finally, load testing assesses the software’s performance under simulated or real-world load conditions, ensuring its ability to handle user requests and maintain stability in various scenarios.
