/**
 * A context for node to provide its dependencies. Acts as a dependency factory.
 * <p/>
 * Normally, there is a default context. But to be able to make tests simpler,
 * to run them faster and in-parallel, it's necessary to avoid network and some heavy-weight
 * objects creations. That's why most of the tests use a special purpose NodeContext.
