What is defined as a collection of tests that do not result in a response or action?

The correct choice is a collection of tests that do not result in a response or action. This describes what is referred to as a building block in the context of system testing. A building block serves as a fundamental component that includes various test scenarios designed for evaluation purposes without generating an operational response. It allows for modular testing and helps define expected behaviors in a controlled environment, all while ensuring that no immediate action is triggered as a result of those tests.

In contrast, a test suite typically represents a set of tests grouped together to assess a particular functionality or feature within a system, often with the expectation of observing certain outputs or results. An action list refers to a compilation of tasks or measures that should be taken in response to certain triggers or alerts. Meanwhile, a response plan outlines the steps and procedures to be followed when specific incidents occur, focusing on reactive measures rather than the testing or evaluation processes.
