APT – Application Parallel Testing

z/OS® Application Testing to Enhance Your DevOps Journey

To keep up with the speed of today’s digitally transformed enterprise, applying testing across both Continuous integration and Continuous Delivery (CICD) into your organization’s DevOps strategy is essential. Infotel’s z/OS Application Environment for Parallel Testing (APT) solution is the only testing tool using VSAM and containerization that leverages automation and isolation of programs and data for faster test cycles.

With APT, the lead time of the most critical and costly stages of the test cycles is greatly reduced so applications are put into production faster and with less resources.

Easily spin up containerized app testing environments for z/OS

APT automates infrastructure preparation processes for testing, enables the reprocessing of a given test, and also enables the creation and execution of isolated test scenarios using Db2, VSAM and Sequential databases, all in a single LPAR. Testing environments can be created both as batch and online transactions (CICS and IMS / DC). By registering the components of the system to be tested, APT allows the user to obtain their own isolated test environment and then test multiple tracks simultaneously.

APT clones (not simulates) entities such as load modules, Db2 tables, files and JCL providing test environment “containers” that behave as if the application were in a live production environment. An application that comes from the distributed platform will actually access the mainframe environment and trigger processes and access to real data and systems.

The result is that these accessed components will be clones of the original components, but the CICS transactions, IMS and Db2 databases are real, not simulated.

Benefits of Parallel Testing for z/OS Applications

APT provides a flexible and cost-saving solution designed to increase application integrity, accelerate production dates and reduce man-hours through automated test environment creation.

The main advantages of the APT agile approach to parallel testing for z/OS applications are:

  • Greater uniformity of tests;
  • Greater agility in maintaining programs;
  • Greater control over what has been tested versus what has not;
  • Test parallelism through isolation in the same LPAR in z/OS environment, without interference;
  • Optimized cloning of components (use only what you need for the test);
  • Plans, Automates and Certifies the integration of tests and their automated reapplication (concept: create-use-rerun) through isolated environments – end-to-end test environment management.
