The purpose of this package is to enable the creation of docker-compose testnets in unit tests.
The tests are longer-running than the standard unit tests, so they are only invoked when the
build tag bdd is added, e.g. go test -v -tags=bdd. The BDD tests log rather frivolously, but
can be quited by adding the flag quiet e.g.go test -v -tags="bdd quiet".
