How is automation of contract verification performed in the CI/CD pipeline?

Automating contract verification in a CI/CD pipeline typically involves the following steps:

1. Defining contracts — API specifications or interactions between services (e.g., OpenAPI, Pact).
2. Writing contract tests — tests verify that services conform to these specifications.
3. Integrating into the pipeline — tests are run automatically with each code change (e.g., in Jenkins, GitLab CI).
4. Reporting and blocking releases — if contract tests fail, the pipeline stops, preventing deployment of incorrect changes.

This approach helps quickly identify integration issues between services and maintain system stability.
