Fake it until you `make it`. API integration testing with WireMock and Testcontainers
Conference (INTERMEDIATE level)
Room 5

Testcontainers has become one of the most popular tools for software integration testing. If you can put your system-under-test into a container, Docker compose cluster or a pod, this is what you're likely to use. If your target isn't ready, not containerizable or just too heavy for testing as is, you can always use mock API testing frameworks like WireMock. Can you combine both approaches? Sure! 
In this talk, we will classify integration testing and discuss application areas for WireMock and Testcontainers, and discuss which tool to choose for each use-case. And why not both? We will discuss putting WireMock into Testcontainers, and getting the best from their features thanks to the new modules and integrations. Last but not least, we will see how to put WireMock in front of the Testcontainers or your real system to do deeper tests or even chaos engineering. 
P.S: We will focus on the Java and maybe Golang examples, but the same approaches can be used in any technology stack for which the Testcontainers SDK is available.
