Microservice pattern: Service component test

[iluwatar]

Description: The Service Component Test design pattern is essential for validating the behavior and functionality of individual microservices within a microservice architecture. This pattern ensures that each service component is thoroughly tested in isolation, allowing for reliable and maintainable code.

Main Elements of the Pattern:

1. Isolation of Services: Testing individual microservices independently to ensure they meet their functional and non-functional requirements without interference from other services.
2. Mocking Dependencies: Utilizing mocks for external dependencies such as databases, third-party services, and other microservices to simulate their behavior.
3. Comprehensive Test Cases: Creating test cases that cover all possible scenarios, including edge cases and failure modes, to validate the microservice's behavior.
4. Automation: Integrating automated testing tools and frameworks to execute tests as part of the continuous integration and deployment pipeline.
5. Clear API Contracts: Ensuring that each microservice has a well-defined API contract that can be tested for compliance and reliability.

Acceptance Criteria:

1. A new module for the Service Component Test design pattern is created in the project repository.
2. Implementation includes examples of service isolation, dependency mocking, and comprehensive test cases.
3. Automated tests are integrated with the CI/CD pipeline, demonstrating successful and reliable execution of the test suite.
