Compuware Acquisition Boosts Mainframe DevOps

August 3, 2018

The acquisition of XaTester, new enhancements, and a partnership with Parasoft moves Compuware Topaz for Total Test toward leadership in the automated unit testing that has become essential for Agile and DevOps on the mainframe.  Compuware clearly has picked up its steady but languid quarterly pace of delivering new mainframe software. This comes on top of Topaz for Enterprise Data announced just a few weeks ago here.

Especially for mainframe shops, automated mainframe unit testing may present the biggest obstacle to speedy new code delivery.  The testing must not just be automated but continuous. As such, it serves as the centerpiece of the entire agile downstream process, which also includes continuous integration and continuous delivery. Only by delivering continuous automated testing can the mainframe shop deliver the no-fail quality of service for which it is heralded. Continuous automated testing is essential for controlling business risk, especially given the increased complexity and pace of modern application delivery.

To put it another way: building and integrating code changes is certainly important. However, if the automated delivery process cannot identify how changes impact business risk or disrupt the end-user experience continuous automated testing then increased frequency and speed of continuous Integration and continuous delivery becomes more of a problem than an advantage.

To deliver on its vision of Topaz for Total Test as the defacto standard for automating mainframe unit testing across all major mainframe environments and programming languages, Compuware has:

  • Acquired XaTester from Xact Consulting A/S, enabling developers to quickly create unit tests for both batch and CICS-based programs written in COBOL, PL/I and Assembler
  • Enhanced Topaz for Total Test to provide automated unit testing for IMS batch and transactional applications. Testing for IMS is especially important given that newer developers often have little or no hands-on experience with IMS code. This presents a challenge since more than 95 percent of the top Fortune 1000 companies use IMS to process more than 50 billion transactions a day and manage 15 million gigabytes of critical business data. Fortunately, IBM continues to add new features to IMS that help adjust to the changing IT world. These enhancements complement Topaz for Total Test’s existing support for batch applications written in COBOL.
  • Partnered with Parasoft, a leading innovator in end-to-end test automation for software development. The first deliverable from the partnership is integration between Parasoft SOAtest and Topaz for Total Test. This integration enables developers working on mainframe applications to quickly and easily test API calls between mainframe and non-mainframe systems, an increasingly critical aspect of DevOps.

Topaz for Total Test transforms mainframe development by giving developers the same type of unit testing capabilities on the mainframe that distributed platform teams have become accustomed to on other platforms. Unit testing enables developers to find potential problems in their code as early as possible to more quickly and frequently deliver incremental changes in software functionality while more granularly documenting code for the benefit of other developers.

DevOps, also presents complications for the mainframe that come from its reputation for slow, painstaking, methodical release cycles. DevOps is about making sure the way an application is deployed in production is the same way it was deployed in test and development.

According to IBM writing in piece titled DevOps for the mainframe, notes DevOps also includes the notion of applying software management to the scripts and processes used for the actual deployment and monitoring and taking the monitoring capabilities from Operations into development and test to get an early understanding of how the system will actually perform.

As the IBM writers continue: In the z/OS environment, organizations are generally building only the changes, the deltas, to the application and deploying them into the environment.  It is very common to find that some parts of an application have not been rebuilt in decades. Worse yet, there are generally few z/OS test environments that are shared across application development teams.  The tools also are rarely the same tools used by the distributed teams.  These differences increase the difficultly of achieving an-end-to-end DevOps process.

This is where Compuware comes in. Topaz for Total Test fundamentally transforms mainframe development by giving developers the same type of unit testing capabilities on the mainframe they’ve become accustomed to on other platforms, mainly x86.

The result for large enterprises, Compuware continues, is a unified DevOps toolchain that accelerates development across all platforms so a multi-platform shop can more effectively compete in today’s rapidly-changing markets. “The new rules of the digital economy are putting pressure on our customers to achieve the utmost speed with the utmost quality,” said Luke Tuddenham, Vice President at CPT, a global IT consulting services firm with a significant testing practice. The new Topaz tools should The acquisition of XaTester, new enhancements, and a partnership with Parasoft moves Compuware Topaz for Total Test toward leadership in the automated unit testing that has become essential for Agile and DevOps on the mainframe. .
