What are the key principles of continuous testing in a DevOps pipeline?

Key principles of continuous testing in DevOps:

• Test automation: all tests should run automatically with every code change.
• Early and frequent testing: tests are run at early stages of development to quickly identify defects.
• Integration with CI/CD: testing is embedded into the continuous integration and delivery pipeline.
• Coverage of different levels: unit tests, integration, system, and load tests.
• Fast feedback: test results should quickly reach developers for prompt correction.
• Quality monitoring: using metrics of coverage, test stability, and execution time.

This helps improve product quality and accelerate the release of new versions.
