COBOL Check! Exciting new development for the Open Mainframe Project’s COBOL Programming course

What this post added

This post introduces COBOL Check, a unit testing framework for COBOL. It details how developers can use COBOL Check on z/OS systems by downloading the package, writing JCL to input programs and unit tests, and receiving test results. The post highlights the framework's support for TDD/TDL and its integration with DevOps practices like automation and CI pipelines (Bitbucket, Jenkins) to prevent code with failing unit tests from reaching production. It also mentions the upcoming 'Testing and Debugging' chapter in the COBOL Programming course that will cover these best practices.
