Re: Spinning up Cayenne in a unit test.

You can still start a BQRuntime in tests, even if the module doesn't use Bootique. Then you'd define a DataSource within BQRuntime, and "bootique-cayenne" would create a DataNode for it automatically and transparently. YMMV with older Bootique versions. E.g. Agrest (that has no Bootique dependency itself) is using Bootique for tests.
