An AS400 Testing job involves evaluating applications running on the IBM AS400 (now IBM i) platform to ensure functionality, performance, and security. Testers work with RPG, COBOL, CL, and DB2-based applications, executing test cases, identifying bugs, and validating system outputs. They use manual and automated testing techniques, including unit testing, system testing, and regression testing. The role requires knowledge of AS400 commands, database structures, and business logic implementation.

To thrive in AS400 Testing, you need a solid understanding of IBM AS/400 (iSeries) environments, RPG/COBOL programming languages, and knowledge of software testing methodologies. Familiarity with tools such as IBM Rational, Selenium, or other test automation frameworks, along with ISTQB certification, is often beneficial. Strong analytical thinking, problem-solving abilities, and clear communication skills help testers collaborate effectively and report findings. These competencies ensure the delivery of robust, high-quality business applications on legacy systems, minimizing risks and defects.
