What are the differences between contract testing and integration testing?

Contract testing focuses on the interactions between services, ensuring they meet agreed contracts, while integration testing checks the overall functionality of combined components.

Can you give me an example of each type of testing?

Sure! In contract testing, you might test that a payment service correctly processes requests from an order service. In integration testing, you would check that the entire order process works from placing an order to payment confirmation.

Which one should I prioritize in my testing strategy?

It depends on your project. If you have multiple microservices, contract testing is crucial to ensure they communicate correctly. Integration testing is essential for overall system functionality.

Are there any tools you recommend for these tests?

For contract testing, tools like Pact are popular. For integration testing, you might consider Postman or JUnit, depending on your tech stack.
