Automating and shift-left testing z/OS hybrid applications Everything you need to get started quickly. Get started - Play overview Transcript

Organizations worldwide are embracing DevOps to transform their end-end development process, establishing a highly automated CI/CD pipeline. Automation isn't enough. Investment in good application-specific test tools is required, as well, to enable best practices like shift-left testing, where unit and application integration testing occur earlier in the pipeline process, allowing problems to be discovered sooner.

z/OS® application testers lack quality tools and readily available infrastructure to quickly and comprehensively test complex multi-tier, hybrid applications. Better tools are needed for teams to apply best practices to deliver quality products to production.

Learn how IBM® solutions for automated, shift-left testing can help deliver higher quality Z-powered, hybrid applications. Benefit significantly from reduced risk and costs, and confidently deliver to production faster whether providing new capabilities or hot fixes to those mission-critical applications.

Overview

Organizations are transforming their development processes and achieving better business outcomes by incorporating DevOps best practices like test automation and shift-left test.

Test automation is a fundamental component of the continuous integration (CI)/continuous delivery (CD) pipeline for code build, test and deployment. Test automation uses tools that include powerful test frameworks to programmatically execute test cases as soon as code is delivered including verifying and recording results. This drives continuous testing from unit test to application integration and performance test, ensuring greater code coverage and fewer defects.

Shift-left test is a best practice in which application integration test occurs early in the CI/CD pipeline, before formal code build, so more complex problems are discovered sooner.

IBM has the expertise and solutions to help your organization develop a strategy to transform testing for your z/OS-powered hybrid applications.

Steps

IBM provides a set of tools to help clients test their z/OS applications and address their challenges and incorporate DevOps best practices for automated, shift-left testing in their CI/CD pipeline.

Learn about solutions to automate and shift left
Overview

The z/OS Automated Unit Test Framework (ZUnit) provides the tools to automate the unit testing of z/OS programs written in the COBOL and PL/I programming languages. It is based upon the open, xunit.net framework. With ZUnit create, record, and run testcases for COBOL and PL/I programs, and provides the following benefits:

  • Gain efficiencies by developing a set of repeatable test cases. Write once and automate.
  • Improve code quality using a programmatic and data-driven approach to gain broader code coverage.
  • Reduce complexity by removing requirements to test with a full middleware stack, by intercepting calls to CICS®, Db2®, and IMS.

Use case

Develop automated test cases for COBOL and PL/I applications including batch and CICS applications.

See a demonstration using COBOL, CICS, and DB2
Overview

IBM Z Virtual Test Platform (zVTP) provides a solution to shift left and perform application integration testing for z/OS applications earlier in the development cycle, and provides the following benefits:

  • Reduce the cost of finding complex bugs late in the cycle by shifting left the application integration testing prior to formal code build
  • Reduce complexity by removing requirements to test with a full middleware stack, by intercepting calls to CICS, DB2, and IMS
  • Improve code quality using record and playback to thoroughly drive code paths, enabling automation.

Use case

Test batch, CICS, and IMS applications written in COBOL, PL/I and assembler.

See IBM Z Virtual Test Platform with use case examples
Steps

Install, set up, and begin developing test cases
Overview

The IBM distribution for Galasa is an open, test automation framework for the end-end, integration testing of z/OS applications that are components of larger hybrid applications. It provides the following benefits:

  • Automate the testing of hybrid applications where z/OS is a component
  • Scale complex, cross-platform application integration scenarios
Use case

SimBank, distributed with Galasa, simulates a mainframe application.

Access the Galasa Community and explore the SimBank use case or download the IBM distribution for Galasa.

Steps

Begin using the IBM distribution for Galasa.

1. Download, install, set up, and begin developing test cases.

IBM DEVELOPMENT AND TEST ENVIRONMENT (ZD&T)

IBM Development and Test environment (ZD&T) provides a z/OS sandbox on x86 hardware, deployed on a personal computer or virtual machine, or as a container on Red Hat OpenShift. and provides the following benefits:

  • Accelerate product deliveries by removing barriers to accessing IBM Z® hardware for complex test scenarios
  • Improve product quality by shifting left application integration testing with a full middleware stack.

IBM VIRTUAL DEV AND TEST FOR z/OS (ZVDT)

IBM Virtual Dev and Test For z/OS (ZVDT) is the industry’s first and only virtual environment that runs current, genuine z/OS software and middleware on-premises Linux on IBM zSystems. It has been developed in lock step with IBM zSystems hardware, offering unmatched performance, application portability and compatibility.

ZVDT was designed to be used for development and early test of new application functions, as well as maintenance changes. Additionally, ZVDT can also be used for:

  • Unit tests, early integration, and functional tests
  • Investigation and verification of new middleware levels (version-to-version upgrades)
  • Prototyping new application architectures
  • Demonstration of application function
  • Internal employee education and training.
