platform is integral to an enterprise-wide continuous integration
and deployment pipeline. Organizations can streamline the DevTest
pipeline using IBM Z Open Development, an integrated development environment that works with Git. IBM Z

Open Unit test makes it possible to
create automated unit tests that are
consistent with the xUnit framework.
Of course, running tests requires using high-quality test data
that meets specific criteria. For
example, to meet security re-

Modern Application
Development and
the Mainframe

FEATURING:

Application Development Is Different
Today Than It Was in the Past
We strive to create products that increase
agility and build better products faster. New technologies like Microservices
and CI/CD, along with cultural shifts, are
responsible for driving these new initiatives. So, how do we include core mainframe applications into this new paradigm? What is the best way to integrate
to mainframe applications?

Join us as we discuss what makes mainframe integration a unique challenge and
how the use of APIs and technologies like
containers can alleviate the process.

quirements, test data must be anonymized. Test data also needs to
reflect real-world production. For
instance, test data shouldn't be so
large that it can't be maintained
efficiently. The integration of Test
Data Fabrication (ibm.co/
2ERSWkh) with IBM Z Development and Test Environment can
help organizations address the
challenges of creating and managing high-quality test data.
4. APIs and
refactoring
"The developer
experience is
fundamental.
We want developers to enjoy using
mainframe services.
Opening up the mainframe using
APIs gives developers who are
going to use mainframe services
a delightful experience," notes
Mitchell. "Open up the mainframe
by designing APIs developers can
understand, that meet their needs
and that can evolve."
There are just as many scenarios and as much need for mainframe assets to use APIs because
mainframes are no longer a monolithic solution. "Applications need
to talk to other systems, and as part
of the mainframe solution, they're
going to need to use other people's
APIs," adds Mitchell. Clients are
already adopting API technologies, reimagining the experience
of consuming mainframe-hosted
services, self-discovering a CICS*
application and liberating data services from IMS* (ibm.co/2WElvf1).
But how are they going to evolve
those APIs over time? What's the
application asset behind that API?
Can the developer be informed by
the use of that API to restructure
the way that the API is serviced by
the application?
Applications created using
multiple components need wiring
to get there. Giving RESTful APIs to
