What type of testing involves executing the software of a component or system?

Dynamic testing refers to the type of testing that involves executing the software to verify its behavior and interact with the application. This testing method focuses on the runtime behavior of the software application and is essential for assessing aspects such as functionality, performance, and reliability while the system is in operation.

During dynamic testing, testers can identify issues that occur when the program is running, allowing them to evaluate the output of executed functions and monitor how the software interacts with various environments or user inputs. This approach contrasts with static testing, which examines the software's code and documentation without running the program, focusing instead on detecting errors based on the expected results from the design or code.

In this context, dynamic testing encompasses various testing types, including unit testing, integration testing, and system testing, which all involve executing components or systems to ensure they function as intended.
