Microservice pattern: Consumer-driven contract test

[iluwatar]

Description:
The Microservices - Service Integration Contract Test design pattern ensures that microservices can communicate and function together as expected. This pattern involves creating and maintaining contract tests that verify the interactions between microservices. These tests help to ensure that changes in one service do not break the functionality of another service, thereby maintaining the integrity of the entire system.

Main elements of the pattern include:

1. Service Contracts: Define clear and precise contracts for each service, specifying the expected inputs and outputs.
2. Consumer-driven Contracts: Consumers of a service define the expectations, which are then verified by the service provider.
3. Automated Tests: Develop automated tests that validate the interactions based on the defined contracts.
4. Versioning: Manage and test multiple versions of service contracts to ensure backward compatibility.
5. Continuous Integration: Integrate contract tests into the CI/CD pipeline to detect and fix issues early in the development process.

Acceptance Criteria:

1. Create service contracts for a sample microservices setup.
2. Implement consumer-driven contract tests and integrate them into the CI/CD pipeline.
3. Verify that contract tests detect any breaking changes in service interactions and provide actionable feedback.
