Integration Testing from the Trenches

on YouTube ↗01h 20m

" summary

Integration testing focuses on real collaborations: use Maven failsafe (remember failsafe requires IT suffix) to keep CI unit builds under five minutes, fake web services with an embedded Spark HTTP server or SoapUI mocks, and prefer H2 use H2 in Mode for DB compatibility over HSQL for faster local runs. Test in-container with Spring Test, TestNG ordering and Arquillian+ShrinkWrap for multiple servers, use a single small connection pool to detect leaks, and favor Java config over XML.
