Which of the following is a benefit of using metrics in the testing process?

Using metrics in the testing process provides a solid basis for comparison with project milestones. This benefit is significant because metrics offer quantitative data that can be analyzed over time, allowing teams to measure progress against predefined objectives and timelines. By leveraging metrics, teams can assess whether they are on track to meet their milestones, identify areas that may need more focus, and make informed decisions to adjust their strategies as necessary.

Metrics can reveal trends in test coverage, defect density, and test execution, among other factors. This data-driven approach enhances the ability to forecast completion dates and resource needs, ultimately contributing to the overall success of the project.

While other aspects, such as team collaboration and the establishment of a test environment, are important, they do not directly relate to the specific advantage of comparison against project milestones provided by metrics. The notion of guaranteeing zero defects is also unrealistic in practical scenarios and doesn’t align with the true purpose of metrics in testing.
