The challenge

Mainframes are used for a reason. They offer guaranteed reliability, unwavering security, and can handle vast amounts of data needed to power “can’t fail” business operations.

Testing mainframes and mainframe integrations is therefore critical. But how to ensure the necessary coverage without limiting your organization’s ability to create an agile pipeline and enhance digital services?

This is where Leapwork comes in.

Less green screen, more automation

Manually testing command lines and green screen can lead to a lot of human error. Leapwork supports easy green screen automation with a codeless terminal emulator.
