You can learn API testing by exploring user-friendly tools like Postman. Understand HTTP basics, like methods and status codes. Start with simple tests, like GET requests, and gradually tackle more complex scenarios.
Check out API documentation for insights into endpoints and parameters. Experiment with authentication methods, and as you gain confidence, dip your toes into automation using frameworks like RestAssured or axios. Remember, it’s a journey – stay curious, and happy testing!

One key piece of advice for getting started with contract testing in microservices is to start small and focus on critical service interactions. Identify the most important or complex interactions between services and create contracts and tests for those first.
This approach allows you to gain experience with contract testing without getting overwhelmed by trying to cover all interactions at once. As you become more comfortable with contract testing, you can gradually expand your coverage to other service interactions.
HI there,
Contract testing is an essential part of microservices architecture. Contract testing simulates interactions between services according to their defined contracts. This allows you to see how individual microservices can handle different loads and data inputs under different conditions.
Contract testing can help you identify inefficiencies and limitations in-service performance. For example, you can see if a service is slow to respond or running a resource-intensive operation. Contract testing also allows you to assess how well a microservices scales under different conditions. This helps you to identify areas where you may need to optimize or add additional resources to ensure smooth scalability.
All in all, incorporating contract testing into your microservices development lifecycle empowers you to proactively solve performance concerns and improve the overall resilience and scalability of your systems.
When dealing with API calls made through a common library across multiple services, centralize your testing. Create a dedicated test suite specifically for the library. This way, you ensure thorough testing without repeating the same tests across all consumers. Additionally, implement integration tests for each service to verify their interactions with the library. This approach minimizes redundancy and ensures comprehensive testing coverage.
To ensure contract tests stay relevant amidst microservices evolution, regularly review and update them in tandem with service changes. Employ version control for contracts and collaborate with teams using tools like Swagger or OpenAPI. Continuous communication and automated testing integration are key for maintaining agility and reliability.
