Video: Effective Testing During Modernizations

When you use automation to modernize applications that you’ve been running for years, there should be no functional change between the legacy code you’ve migrated from and the target language you’ve transformed to. That dramatically simplifies testing.

As Scott Pickett explains in the latest episode of our “Migrating Your Mainframe to the Cloud” video series, you can create quick test scripts to confirm that the business logic has stayed exactly the same. From there, knowing that the automated modernization has created that like-for-like codebase in the new target language means that you simply need to confirm that the data baselines you set are in sync and you’re off to the races!

As Scott does note, TSRI’s solution does inject telemetry into the modernization so you will have logs to help with those code and data comparisons, which makes the full testing process that much simpler.
