What is a Mainframe QA?

A Mainframe QA (Quality Assurance) professional is responsible for testing and ensuring the quality of software applications that run on mainframe systems. They develop and execute test plans, identify defects, and verify that mainframe applications meet business and technical requirements. Mainframe QA specialists often use specific tools and methodologies tailored for mainframe environments, such as JCL, COBOL, and batch processing. Their work helps prevent issues in critical business operations that depend on mainframe computing.
