Key Notes For Successful Continuous Testing In DevOps

  • Create strong user stories: Continuous testing means carrying quality and granular testing from the very beginning. Make sure you get good business requirements to start development. Ensure user stories are testable and have a good set of acceptance criteria, Adopting a more exploratory attitude to test manually might help to get good results.

  • Collaborate: From a cultural point of view, continuous testing in DevOps is successful if everyone exhibits quality and cooperation among the team. Test cases are described before coding is started or tests are written as necessary. In any case, developers and test automation architects should work together to ensure that the code for test automation is optimized. Teams may also cooperate on test results using tools like Slack to speed feedback and debugging.

  • Keep it simple and logical: Reduce unnecessary test objects, such as extensive test plans and test cases, and reduce test waiting times. Tests should be consistent, incremental and reproducible; results should be quantifiable and meaningful.

  • Test everywhere: Testing must be carried out at all stages of the delivery pipeline, covering all the aspects of the entire environment be it production or Staging environment. By testing at each and every stage and continuously providing feedback to the developers can help in improving the quality of software development.

  • Automate your testing: Automation testing plays a major hand towards a successful implementation of continuous testing in DevOps. It is vital to stick towards a test automation pyramid and to focus on automating test scripts towards the latest updates in a web application as well. A 100% automation isn’t achievable but the more you can automate your process the faster you can perform continuous testing.

  • Embrace CI/CD (continuous integration/continuous delivery): Developers should adopt continuous integration – by integrating code several times a day into shared repositories such as Bitbucket and GitHub. When automated testing is implemented with a CI server, continuous testing immediately starts for each build. Warnings, with passing or failing test results, can be delivered in real time directly to the development team. By integrating regularly, you can quickly detect and locate errors more easily. Once all the tests have been completed, updates can be delivered to production continuously without hesitation.

  • Choose API over GUI: DevOps and Agile teams working with short release cycles, fast feedback loops, and frequent changes, find difficulty in maintaining GUI tests. GUI testing takes longer time in providing feedback and requires a lot of rework. For modern applications with multitier architectures, it is important to verify back-end services and functional paths; API testing is more stable and recommended for the same. Where GUI testing is limited to system testing, mobile testing, black-box testing; API testing involves many practices such as unit testing, functional regression testing, load testing, security testing, web interoperability testing and many more.

  • Think beyond automation: Just like human brain works, implementing artificial intelligence(AI) and designing intelligent machines (with help of IoT, quantum computing, robotics etc.) that perform heuristic thinking of each and every stage of the delivery pipeline can accelerate the entire SDLC.
