MAINFRAME MODERNIZATION

Automated Testing

Our Automated Testing solution alleviates the pain of manually developing test scripts for migrated online and batch applications within the scope of a modernization initiative. It also ensures functionally equivalent testing for efficient defect identification and rapid remediation. This reduces cost, resource burden, and modernization project timelines, ensuring optimal performance of the modernized estate in production.

Why modernize?

CHALLENGES

Scarcity of domain expertise

Developers who understand mainframe technology are reaching retirement age and no one is being trained to replace them, resulting in a steadily diminishing talent pool. As this shortage grows, the costs and risk of relying on the mainframe will continue to rise.

Limited flexibility

Companies are rapidly moving to modern environments and practices such as DevOps and the Cloud. The mainframe and the underlying systems that support it were not designed for modern IT. This results in difficult integrations and limited flexibility.

 

Exorbitant costs

Mainframes cost as much as 4,500 percent more to operate than equivalent Cloud counterparts. This figure is compounded by rising licensing and maintenance fees for ancillary mainframe applications and databases. 

Automated Testing

OUR SOLUTION

Testing is a critical phase of any modernization project and typically accounts for over 50 percent of the entire modernization effort. Although key business logic is retained through modernization efforts, the underlying applications are adapted to work within a new target operating environment. Thus, a detailed validation of the migration is extremely important, and the best means of achieving that validation is with thorough testing.

Testing is often burdensome to customers because subject matter experts are tasked with documenting step-by-step use cases for replication in the new environment. These subject matter experts are power users who have a deep working knowledge of the legacy operating environment and are often business-facing and non-technical. This combination of circumstances can result in oversight and miscommunication in test execution, which adds significant time and effort to modernization projects.

Our Automated Testing solution provides customers with a tool to trace actions in online applications on the mainframe using IBM PCOM (or another TN3270 emulator). It also offers a means for recording, executing, and comparing batch jobs across the source and target operating environments. This automation removes the human element from key activities, reducing the potential for miscommunication and decreasing the time it takes to develop and execute comprehensive test cases.

Batch testing

Using the Automated Testing solution, mainframe assets, including source code and job scheduler definitions, are populated into our Modernization Platform-as-a-Service (ModPaaS), which is integrated into the CI / CD test pipeline.

The ModPaaS engine then parses and analyzes batch assets, determines batch streams, and generates batch test assets (test scripts, test cases, etc.). These test assets are executed against the mainframe (source) environment and the target environment. The results of which are compared using our Automated Testing toolset, which generates reports and insights for review in a centralized dashboard.

Online testing

Subject matter experts connect to the test environment using a terminal emulator, where our Automated Testing solution records sessions. These recordings are encrypted and transferred to ModPaaS, where the 3270 trace files are replayed and processed. Test cases for the target environment are automatically generated from these recordings, passed to the CI / CD test pipeline, compared using our Automated Testing toolset, and presented by way of our centralized monitoring dashboard.
