DevOps and Testing

• DevOps makes continuous deployment possible by integrating test steps as part of the validation, verification, and deployment process.
• DevOps requires 100% confidence in your test suite and testing environments, as they are the gate between a release going out or not.
• Not just unit, integration, and end-to-end tests. Any sort of “testing” process can be used to identify defects and regressions, e.g., monitoring code instrumentation and application metrics to catch performance regressions.

Benefits

1. Fast Feedback
2. Shift-left approach (TDD, static analysis)
3. Stable, predictable, and production-quality test environments
4. View on non-functional characteristics (e.g., security, performance)
5. Reduces manual testing as DevOps is about automation
6. Minimized regression risk through automated testing
7. Optimal configuration of CI/CD test jobs and pipelines for speed and reliability
8. CI/CD tool maintenance
