#51 Consumer Driven Contracts as TDD on API level

Lecturer: Marcin Grzejszczak

Consumer Driven Contracts (CDC) are like TDD on API level. This approach is extremely important in the world of microservices. Due to the fact that it is driven by API consumers, the produced API is definitely more user-friendly.

At many conferences, you can learn that everyone makes microservices and does them perfectly. Rarely is mentioned about testing them (who needs testing, right?). Later, when it comes to production implementations, it turns out that end to end testing lasts 10 hours each and explodes on the last test due to a typo in the API.

During the lecture, we will write an application using the CDC approach. You will see how easy it is to write a consumer driven API and what the full contract testing process looks like. We will use tools such as Spring Boot, Spring Cloud, Spring Cloud Contract, Jenkins, Gitlab and Artifactory.
