It is easy to misconfigure something, especially when database statements are involved. The level of integration tests should be far lower than the coverage of the unit tests, and again, we need to be able to run these tests in a reproducible environment. Docker is an excellent ally in this situation; we can leverage the capability of Docker to run in multiple environments. This enables us to configure and debug our integration tests on our local environment before executing them on the build server. In the same way that unit tests are a gate to a successful build, so are integration ...
