YouTube series explaining how to use WireMock for mocking the HTTP communication to external systems for integration tests.

With this last video lesson, we’ll take a look at the WireMock test setup for JUnit Jupiter (part of JUnit 5).

While the sample application uses Spring Boot, you can use this testing recipe for any Java application.
