Creating unit tests for COBOL is still one of those tasks that sounds simple in theory, but becomes time-consuming very quickly in practice. That is exactly why we started building CutGEN: to make the generation of COBOL Check compatible .cut files faster, easier, and more practical with AI support. In our earlier post on CutGEN – Intelligent Unit…
Maintaining and evolving legacy COBOL applications continues to be a challenge for many organizations. Over time, systems grow in complexity, documentation becomes fragmented, and understanding behavior often requires significant manual effort. Improving visibility with CodeRevive With CodeRevive for COBOL, we addressed this by creating transparency across the entire system landscape. The January 2026 updates introduced…
Why Generating Unit Test Cases is Important In 1996, the Ariane 5 rocket exploded just 37 seconds after launch. The cause? A single line of unhandled code that wasn’t properly tested. Cost: $440 million and years of work, gone in an instant. Your COBOL programs might not launch rockets, but they do something just as…
