### Question:
EndpointDescription implements MultiNode { public boolean matches(String filter) { Filter f; try { f = FrameworkUtil.createFilter(filter); } catch (InvalidSyntaxException e) { IllegalArgumentException iae = new IllegalArgumentException(e.getMessage()); iae.initCause(e); throw iae; } Dictionary dictionary = new Properties(); for (Map.Entry<String, Object> entry : properties.entrySet()) { String key = entry.getKey(); Object value = entry.getValue(); dictionary.put(key, value); } return f.matchCase(dictionary); } EndpointDescription(String id, Node node); boolean matches(String filter); String getId(); Set<Node> getNodes(); void setNodes(Set<Node> nodes); Map<String, Object> getProperties(); final String getServiceClass(); @Override boolean equals(Object o); @Override int hashCode();  }### Answer:
@Test public void testMatches() throws Exception { String testEndpointFilter = String.format(filterPattern, objectClass); String endpointId = objectClass + Constants.SEPARATOR + "1.0.0"; EndpointDescription endpointDescription1 = new EndpointDescription(endpointId, null); EndpointDescription endpointDescription2 = new EndpointDescription(endpointId, null); Assert.assertTrue(endpointDescription1.matches(testEndpointFilter)); Assert.assertTrue(endpointDescription2.matches(testEndpointFilter)); }
