Open Mainframe Project Welcomes Galasa into its Ecosystem

By | September 11, 2023September 14th, 2023

The new project adds a key layer of testing tools for hybrid cloud applications



SAN FRANCISCO, September 11, 2023 The Open Mainframe Project, an open source initiative that enables collaboration across the mainframe community to develop shared tool sets and resources, today welcomed Galasa, a project that offers developers the ability to test applications at scale regardless of platform including z/OS, into its ecosystem.

“Open Mainframe Project is thrilled to welcome Galasa as an open source testing platform,” said John Mertic, Executive Director of Open Mainframe Project. “Under our umbrella, we’re arming developers with a variety of development, test and continuous delivery environments. This will ultimately provide the mainframe community with the tools they need to deliver secure and innovative solutions to their customers.”

Galasa is an open source deep integration test framework designed for agile, reliable, and scalable testing across various technologies and platforms. By supporting consistent testing without code changes, enabling multi-technology integration, and providing efficient test data management, it enhances developer operations strategies.

It centralizes test results, simplifies test planning, and offers extensibility without vendor lock-in. With a focus on hybrid cloud testing and seamless integration into CI/CD pipelines, it empowers organizations to achieve faster, more comprehensive software testing and delivery.

“Galasa is designed to help mainframe modernization within hybrid cloud environments and increase the reliability of repeatable software releases,” said Louisa Seers, Chair of the Galasa Technical Steering Committee and Product Manager at IBM. “Open Mainframe Project will help create a joint collaboration between different and separate subsystems and generate growth in the connection between cloud and mainframe environments.”

Future goals include Galasa partnering with other projects such as COBOL Check to enhance and integrate COBOL testing within the environment and gain access into the education within. Seers also foresees working with the Zowe community to create a plug-in to test the changes made through the Zowe CLI. Learn more about Galasa.

In addition to welcoming Galasa, Open Mainframe Project has achieved other milestones including:

  • The 5-year anniversary of Zowe, which continues to make its mark for mission-critical applications and data processing. Zowe ensures product stability, security and interoperability with the support of a large open source community.
  • Mainframe Open Education moves from the Incubation stage to the Active Project stage, which means it is fully mature and operating as an open, transparent and sustainable project. Learn more.
  • New developer resources for Linux on s390x. Since support for Linux on IBM Z has been around for more than 20 years, dozens of languages and frameworks, and hundreds of major open source applications have been ported. A sampling of them can be found by searching the Open Mainframe Project Software Discovery Tool with dozens of updates being made each month — and the sea of applications continues to grow. Check out the new resource here.
  • More Zowe training through a collaboration between Open Mainframe Project and Interskill, which includes an updated “Basics for Zowe” course and a new “Fundamentals for Zowe.“ Developers who go through these courses will receive Open Mainframe Project digital Learn more.

The news was announced at Open Mainframe Summit Las Vegas*, which is part of the IBM TechXchange Conference 2023 Community Day on September 11 at the MGM Grand Hotel. Community Day unites diverse groups and technical communities to foster collaboration, networking and learning.

Open Mainframe Project will host another event in New York on November 1, co-located with FINOS’ Open Source in Finance Forum. Open Mainframe Summit New York will have a 10-minute keynote presented and 6 sessions focused on open source technologies for the financial sector.

The agenda for Open Mainframe Summit New York includes:
