9+ Hours of Video Instruction

Developers need confidence when pushing new features to a new application or service in a distributed system. Contract testing is a technique that lets developers catch issues early at application build time. Thanks to such testing, you can apply the fail fast approach and break the build if there’s an issue, all in the hopes of easing continuous delivery and deployment. With the tips in this video, developers can learn to catch issues early, and avoid the need to run heavy and costly integration tests.

This 9+ hour LiveLesson video course teaches developers how to apply the provider and consumer-driven contract testing approaches, for Spring and non-Spring based applications, with Spring Cloud Contract. There is coverage of JVM and non-JVM services, as Spring Cloud Contract can be used in a polyglot environment.

The lessons cover building JVM and non-JVM applications, leveraging contract tests to drive the change of the API, as well as performing the provider and consumer-driven contract tests. In addition, developers learn how to use Spring Cloud Contract to verify whether current testing customs are correct, leverage Spring Cloud Contract Stub Runner to automatically fetch and run stubs, and use Docker to generate and test non-JVM based applications.
