After a new build gets deployed and automated tests executed, SLIs are evaluated against their SLOs and, depending on that result, a build is considered good (promoted) or bad (rolled back). “ The app description and supporting files such as load testing scripts are on the Keptn Example GitHub. This is what this blog is all about.

Many organizations already employ DevOps, an approach to developing software that combines development and operations in a continuous cycle to build, test, release, and refine software in an efficient feedback loop. Traditionally, application security testing sits as a discrete stage between development and operations.

Regression testing comprises re-running the test cases of already stable features and finding out if the new code changes attributed to the new release led to any negative impacts on the existing functionalities. When is Regression Testing done? Regression tests should be performed just after the sanity testing is complete.

If there is strong disagreement between one or more principles that some feel should be combined while others feel should be separate, then run a dot-voting prioritization exercise. It is best practice to segment by demographics only with quantitative samples where meaningful differences may be found through statistical analysis.
