Agile Development and DevOps emphasize quick feedback cycles. But how do we test non-trivial applications with many components? What do we do when some components are outside of our control, expensive to access, or simply not ready to test against? Delaying integration testing or running the tests infrequently is can cause problems to linger, quality to fall, and delivery delays.

  • 1. © 2013 IBM Corporation Learn Faster Deploy what you have, Virtualize what you don’t
  • 2. © 2013 IBM Corporation Who are these guys? • Eric is a DevOps Evangelist with IBM where he helps customers get the most out of their build, deploy and release processes. • Today he works with customers and industry leaders to find the best ways of adopting continuous delivery and DevOps. • @EricMinick Eric Minick • Al is a Testing Evangelist at IBM focused on quality management and testing. Having performed many development roles over a number of years and armed with real-world experience for the testing challenges organizations face. • Al has spent the last two years raising awareness for Service Virtualization and how it is the enabler to Continuous Testing! • @Al_Wagner Al Wagner
  • 3. © 2013 IBM Corporation Delayed learning is why waterfall fails Idea Requirements Development Integrated Test Release Weeks / months to validate code matches Reqs Months or years to learn if ideas / requirements match the market need
  • 4. © 2013 IBM Corporation Time to customer feedback is governed by risk Traditionally • Organizations looked to find a balance between speed, cost & risk. • Development teams were not as agile as they are today; testing never seemed to have enough time.
  • 5. © 2013 IBM Corporation Time to customer feedback is governed by risk Traditionally • Organizations looked to find a balance between speed, cost & risk. • Development teams were not as agile as they are today; testing never seemed to have enough time. *Survey of 250 Testers 90% of testers have some but not “complete” confidence in the software that’s released. 4 testers are seeing faster releases per 1 that sees slower 34% of those who expressed no change were regularly releasing quarterly or better.
  • 6. © 2013 IBM Corporation Shift Left: To win in the market, learn faster • Organizations are asking teams to release higher quality software sooner. • Development teams are becoming more and more agile; testing still never seems to have enough time.
  • 7. © 2013 IBM Corporation Today’s Focus: Integration Testing Pretty Great Castle, huh? Just need to do that little integration part at the end.
  • 8. © 2013 IBM Corporation Late integration testing: Design verification occurs too late in the lifecycle 100% Project Schedule DevelopmentProgress (%coded) Original Target Date Integration Begins
  • 9. © 2013 IBM Corporation Earlier validation leads to a smoother curve 100% Project Schedule DevelopmentProgress (%coded) ♫
  • 10. © 2013 IBM Corporation Basic strategy 1. Deploy all the stuff into a test environment 2. Setup test scenarios 3. Run regression tests 4. Create “known good” version of the system 5.

  • 11. So… why aren’t we all doing this?
  • 12. © 2013 IBM Corporation Composite applications have lots of pieces Image from ischool.tv
  • 13. © 2013 IBM Corporation Deploying composite applications Challenges 1. Deploy all the stuff into a test environment 2. Setup test scenarios 3. Run regression tests 4. Create “known good” version of the system 5. Repeat when there are changes Need to coordinate change Link to provisioning Track / collect versions under test

  • 16. © 2013 IBM Corporation Deploying composite applications Challenges 1. Deploy all the stuff into a test environment 2. Setup test scenarios 3. Run regression tests 4. Create “known good” version of the system 5. Repeat when there are changes Track / collect versions Create a logical version of what was tested together, for deployment to later environments.
  • 17. © 2013 IBM Corporation Testing is often plagued with bottlenecks & delays Today’s testing challenges 1. Difficult to automate tests when the dependent services have yet to be developed 2. Lack of complete production like test labs 3. Software and/or systems don’t exist yet as priorities may differ across development teams 4. Testing with 3rd party services may incur access fees driving up the cost of testing 5. Blocking defects may interrupt end-to-end testing 6. There just isn’t enough time due to all the interruptions! There must be a way which allows Testers to test What they want, When they want, How they want!
  • 18. © 2013 IBM Corporation Where do Testers want to spend their time? Creating Automated Tests Performing Exploratory Tests Executing Automated Tests Designing Tests Planning Tests Reviewing Test Results Running Pre-defined Tests Maintaining Automated Tests I want to spend MORE time… I want to spend LESS time… Creating Reports Maintaining Automated Test Tools Configuring Test Tools Creating Test Data Re-running tests Investigating, Documenting and Submitting Defects Setting Up Test Labs
  • 19. © 2013 IBM Corporation Continuous Testing means… Validating today’s composite applications earlier and at a lower cost Continuous Testing DevOps Foundation Test Automation • Run unattended • Validate business flows across channels • Durable, maintainable, resilient to change Automated Deployment Into Test Environments • Reliable • Repeatable • Traceable Test Environments • Realistic & complete - (production like) • Available on demand • Inexpensive to setup
  • 20. © 2013 IBM Corporation Continuous Testing means… Making production-like test environments a reality  Traditional test environments are both underutilized and insufficient – Environments are expensive: hardware, software, and labor – Tester and developer time wasted waiting for appropriate environment  Agile test environments require four enabling capabilities Dynamic Infrastructure Deployment Automation Test Environments DevOps Foundation Service Virtualization Test Data Management
  • 21. © 2013 IBM Corporation Time Spent on Test Data Management
  • 22. © 2013 IBM Corporation Organization Process Technology an agile test organization and testers need continuous access to test data with agile development you have continuous integration and delivery and have to test often test data management software needs to support agile method by streamlining access to test data and having insight into test data Test Data Management with IBM InfoSphere Optim Agile testing needs continuous access to test data

  • 24. © 2013 IBM Corporation Continuous Testing improves software quality Actual Service/App Virtual Service/App Service Virtualization can simulate the behavior of a service or application for the purposes of testing Service Virtualization is an enabler for continuous testing  Services, applications, systems are introduced into the continuous integration cycle in a prioritized, controlled fashion. Controlled integration helps isolate defects for faster resolution. Service virtualization enables continuous integration testing Using Service Virtualization Enables testers to test continuously with control
