Mainframe Testing: Process, Challenges, Best Practices, and More

Originally developed in the 1950s, mainframes are powerful, high-performance computing systems designed to handle large-scale transactions and data processing for enterprises. Despite their age, mainframes have only gotten more ubiquitous with age, continuing to be the backbone of critical industries like banking, healthcare, and retail.

Right now, mainframes handle 68% of global IT workloads while consuming just 6% of overall IT expenses. This exceptional reliability, availability, and security allows mainframes to remain widely used despite the existence of cloud solutions and edge computing. At the same time, mainframes require rigorous testing to ensure uninterrupted operations, data integrity, and seamless integration with modern applications. Find out how to test mainframes and what else to know to make the testing process even more effective.
