### Question:
InstanceHelpers { public static boolean isTarget( Instance instance ) { return instance.getComponent() != null && ComponentHelpers.isTarget( instance.getComponent()); } private  InstanceHelpers(); static String computeInstancePath( Instance inst ); static boolean haveSamePath( Instance i1, Instance i2 ); static String findInstanceName( String instancePath ); static List<Instance> buildHierarchicalList( Instance inst ); static void insertChild( Instance parent, Instance child ); static Map<String,String> findAllExportedVariables( Instance instance ); static Instance findInstanceByPath( AbstractApplication application, String instancePath ); static Instance findInstanceByPath( Instance rootInstance, String instancePath ); static List<Instance> findInstancesByComponentName( AbstractApplication application, String componentName ); static Instance findRootInstance( Instance instance ); static Instance findScopedInstance( Instance instance ); static List<Instance> findAllScopedInstances( AbstractApplication app ); static List<Instance> getAllInstances( AbstractApplication application ); static boolean tryToInsertChildInstance( AbstractApplication application, Instance parentInstance, Instance childInstance ); static boolean hasChildWithThisName( AbstractApplication application, Instance parentInstance, String nameToSearch ); static File findInstanceDirectoryOnAgent( Instance instance ); static int countInstances( String instancePath ); static Instance replicateInstance( Instance instance ); static boolean isTarget( Instance instance ); static void removeOffScopeInstances( Instance scopedInstance ); static String findRootInstancePath( String scopedInstancePath ); static void fixOverriddenExports( Instance instance );  }### Answer:
@Test public void testIsTarget() { Instance inst = new Instance( "i" ); Assert.assertFalse( InstanceHelpers.isTarget( inst )); inst.setComponent( new Component( "comp" ).installerName( "whatever" )); Assert.assertFalse( InstanceHelpers.isTarget( inst )); inst.getComponent().setInstallerName( Constants.TARGET_INSTALLER ); Assert.assertTrue( InstanceHelpers.isTarget( inst )); }
