Example 6 with AriesSubsystem

use of org.apache.aries.subsystem.AriesSubsystem in project aries by apache.

the class AriesSubsystemTest method testAddRequirements.

/*
	 * Test the AriesSubsystem.addRequirements(Collection<Requirement>) method.
	 * 
	 * There are several things to consider for this test.
	 * 
	 * (1) Installing a child subsystem before the requirement has been added
	 *     should fail.
	 * (2) Installing a child subsystem after the requirement has been added
	 *     should succeed.
	 * (3) The newly created region should contain all of the bundles from the
	 *     old one.
	 * (4) The connections between the subsystem with the added requirement and
	 *     its parents should be reestablished.
	 * (5) The connections between the subsystem with the added requirement and
	 *     its children should be reestablished.
