use of org.apache.aries.subsystem.core.archive.Clause in project aries by apache.

the class ResolutionTest method testContentWithNonConstituentDependencyWithNonConstituentDependency.

/*
	 * Test that the right regions are used when validating capabilities.
	 * 
	 * Application A contains a content bundle requiring capability A. Bundle B
	 * provides capability A and is available as an installable resource from a
	 * repository service. Bundle B also requires capability B. Bundle C is an
	 * already installed resource in the root subsystem providing capability B.
	 * When validating capability A, the subsystem should use the root region as
	 * the from region, and its own region as the to region. When validating 
	 * capability B, the subsystem should use the root region as the from region
	 * as well as for the to region.
