How are automated tests integrated into the CI/CD pipeline and how are they run?

Automated tests are integrated into the CI/CD pipeline as follows:

• Every commit or pull request automatically triggers the project build.
• After a successful build, unit tests are run to check individual code modules.
• Then, integration and functional tests are executed to verify component interactions and business logic.
• If any test fails, the pipeline stops, and the team receives a notification.

Tests are usually run using a CI system (e.g., Jenkins, GitLab CI, GitHub Actions), where the test steps are described in a configuration file, for example:

stages:
  - test

test_job:
  stage: test
  script:
    - go test ./... -v

Thus, tests automatically verify code quality at each development stage and before deployment.
