Thorough automation in application testing is crucial for guaranteeing the dependability and optimal performance of cloud-native applications, particularly when prioritizing a rapid time-to-market approach through Continuous Deployment.
The approach includes unit testing, integration testing, contract testing, and end-to-end testing.
- Unit testing: A unit test exercises the smallest piece of testable software in the application to determine whether it behaves as expected.
- Component Testing: A component test limits the scope of the exercised software to a portion of the system under test, manipulating the system through internal code interfaces and using test doubles to isolate the code under test from other components.
- Contract testing, facilitated by tools like Pact, ensures that services adhere to the agreed-upon API contracts.
- Integration testing: An Integration Contract test is a test at the boundary of an external service verifying that it meets the contract expected by a consuming service.
- End-to-end testing: An end-to-end test verifies that a system meets external requirements and achieves its goals, testing the entire system from end to end.

Order Microservice is part of an eCommerce Application. The objective of selecting this Microservice is to demonstrate various testing frameworks. As Order is a complex service with internal (Ex. Inventory, Warhouse, Shipping etc) and external (Payment) service integration and it has all the requirements to use various testing frameworks. The objective is to demonstrate various testing frameworks.
Order Service REST Endpoints are documented using Open API v3. You can access the API's using http://localhost:9081/test-service/api/v1/swagger-ui/index.html#/
Other Services
- Payment External Service
- Shipping Service
- Inventory Service
- Warehouse Service
Currently Order Service has a Mock Implementation of these services.
Now let us focus on Microservices Testing Strategies.
The following Test Categories helps you to automate the testing for Microservices based development resulting in ZERO End-2-End Testing.
All the tests will be fully automated as part of your CI/CD pipeline.
- Spring Boot 3 (3.3.4)
- Maven SureFire Plugin 2 (3.0.0-M7)
