You'd be adding Bootique dependencies to the test scope only, so none of it
should leak to the modules that include your .jar. But there is a Bootique-free
solution as well. See below.

Overriding connection properties affects a pre-existing DataNode. It won't
create a new one. But using explicit ServerRuntimeBuilder API would result in
creation of a so-called "synthetic" DataNode behind the scenes. So rewrite the
above as follows:
runtime = ServerRuntime.builder()
.addConfig("cayenne-CohortManager.xml")
.jdbcDriver("org.h2.Driver")
.url("jdbc:h2:mem:CohortDB")
.build();
and this should produce a working stack.
