ServiceNow upgrade checklist: A step-by-step guide to improving the release process

ServiceNow updates can be time-consuming and risky. From system updates to extensions of the user interface, even seemingly minor changes can significantly impact system behavior. Due to the Now platform’s extreme versatility, it is nearly impossible to test manually, especially in broad installations with equally broad testing requirements. Traditionally, developers and testers work independently to ensure the code is working as expected. Thorough testing takes time and patience. The back and forth, human errors, and constant effort to capture fundamental changes to the core system to avoid defects are very difficult to manage through manual testing.
 
Adopting test automation can provide consistency and peace of mind. Test automation provides immediate feedback on a breaking change and saves testing time over the long run. To control the risk of the next ServiceNow upgrade, establish a reliable safety net with an effective test automation strategy. Ideally, this strategy:
 
  • Includes multiple levels of testing to be used at all stages of development
  • Defines how requirements should be used to create tests and how those tests should be organized and maintained
  • Outlines how and when tests should be executed and how defects should be logged from the results
