The test library creates a temporary state and runtime directory, starts the server with the specified configuration file and lets you interact with it using a couple of convenient wrappers.
To run tests, use go test -tags integration in this directory. Make sure to
have a maddy executable in the current working directory.
Use -integration.executable if the executable is named different or is placed
somewhere else.
Use -integration.coverprofile to pass -test.coverprofile your_value.RANDOM to test executable. See ./build_cover.sh to build a
server executable instrumented with coverage counters.
