Description

In our previous course, Contract Testing with Spring Cloud Contract, we delved into how Spring Cloud Contracts can be a powerful tool for creating reliable contract tests specifically for HTTP communications. By implementing these tests, you can provide confidence to your team during production releases and create solid integration tests that reduce dependencies on other teams. However, contract testing with Spring Cloud Contracts isn’t limited to just HTTP. This course focuses on extending the power of contract testing to message-based communication—a critical area for ensuring stability and reliability in distributed systems.We’ll take you through hands-on examples using two small applications that communicate through RabbitMQ, guiding you in setting up contract tests for these message-based integrations. If RabbitMQ is new to you, there’s no need to worry; we’ll start with a primer on RabbitMQ basics before diving into the contract testing specifics. After this course, you will be able to implement contract testing regardless of the message broker your project is using (Kafka, ActiveMQ, SQS, etc).To fully harness the value of this course, you should ideally have a foundation in Java, basic Spring Boot, and be familiar with unit testing concepts, particularly with tools like Mockito and JUnit. This background will help you maximize the course's insights and apply them effectively to your own projects.
