Which of the following is an example of testing during the requirements specification phase?

A requirements review meeting is a prime example of testing during the requirements specification phase because it involves evaluating the requirements to ensure they are clear, complete, and feasible. During this meeting, stakeholders, including testers, can provide feedback on the requirements, identifying any ambiguities or inconsistencies early in the project. This allows for the identification of potential issues before development begins and helps ensure that the requirements align with customer needs and expectations.

This practice is essential as it places emphasis on verifying that the requirements themselves are of high quality, which is a foundational aspect of effective testing. Detecting issues during this phase means they can be addressed before they propagate into later stages of the development lifecycle, where they could become more costly and complicated to fix.

The other options do not specifically align with the concept of "testing during the requirements specification phase." For instance, eliciting requirements focuses on gathering information rather than validating the requirements themselves. Performing acceptance tests and producing a test report are activities that typically occur after the requirements have been defined and implemented, thus falling into later stages of the software development lifecycle.
