Who is a skilled professional involved in the testing of a component or system?

A skilled professional involved in the testing of a component or system is primarily referred to as a tester. Testers are specifically trained to design, execute, and evaluate tests to ensure the quality and functionality of the software. Their role is focused on identifying defects, verifying features, and validating that the product meets specified requirements.

Their expertise includes creating test cases, executing them effectively, understanding testing methodologies, and using testing tools to automate and streamline the testing process. This specialized knowledge not only ensures that the testing is thorough but also allows for the identification of potential improvement areas in the software.

While developers, analysts, and managers may all play essential roles within the software development lifecycle, their primary focus is not solely on testing. Developers primarily focus on writing and debugging code, analysts concentrate on requirements and user stories, and managers deal with project oversight and resource management. Because of this distinct focus on testing and quality assurance, the tester is recognized as the skilled professional dedicated to this essential task in the development process.
