Top 8 Mainframe Testing Tools In 2024

Top Mainframe testing tools
Posted On: 11 October 2024

Mainframe testing evolved as mainframes became critical for large-scale business operations. Early mainframe testing was manual, focusing on verifying hardware and business-critical applications. IBM System/360, introduced in 1964, marked the rise of complex, multi-application environments that required specialized testing. Later, automated tools emerged to manage repetitive testing, ensuring consistency across mainframe operations. With continuous testing, mainframe testing has adapted to today’s agile environments.

The mainframe is a high-speed multi-user computer system used for larger-scale computing. This system requires a high level of availability and security. Mainframe testing is a process of testing software applications based on mainframe systems. The purpose of mainframe testing is to check the performance, reliability, and quality of software applications by verification and validation methods and proceed to deployment. Mainframes are commonly employed in industries such as finance and other essential areas where large amounts of data must be processed several times.

The top 8 mainframe testing tools to verify and validate methods before deploying applications:
