Senior testers are professionals who supervise junior-level testers that conduct testing for computer software for errors or any problems faced by end-users. These testers must attend discussion meetings to review and analyze business requirements and technical specifications with developers and business users. They must work with the quality assurance (QA) team to identify discrepancies and test the new application. Senior testers must also gather test results and document all defects to create the test completion document as per the requirement of end-users.
