//
// OVERVIEW
//
// This is the test suite for BgpConfigListener class and DependencyTracker
// nested class. The BgpConfigData that gets populated in BgpConfigManager
// does not trigger the creation of any operational state since there's no
// BgpConfigManager::Observers registered.
//
// A BgpConfigListenerMock class is used. It's GetChangeList method doesn't
// do anything when processing is disabled.
//
// In addition to testing the common code in the BgpConfigListener and the
// DependencyTracker, the tests also cover each of the terms in the policy
// that's specified via the listener's Initialize method. New tests should
// be added as and when the policy is modified.
//
// TEST STEPS
//
// 1. Setup creates all the IFMap tables and initialize BgpConfigManager.
// 2. Each test creates the desired configuration by parsing a test config.
// 3. Some tests create additional configuration using the ifmap_test_util
// infrastructure.
// 4. Wait for all configuration to be processed and reach steady state.
// 5. Disable propagation to the change list in the BgpConfigListenerMock.
// 6. Trigger the appropriate IFMapNode and/or IFMapLink events using the
// ifmap_test_util infrastructure.
// 7. Verify number of entries on the ChangeList in the BgpConfigListener
// and number of entries in the NodeList and EdgeDescriptorList in the
// DependencyTracker.
// 8. Ask the BgpConfigListener to process the items in the NodeList and in
// the EdgeDescriptorList and propagate the changes into the ChangeList.
// 9. Verify total number entries on the ChangeList and number of entries
// of each identifier type.
// 10. Enable propagation to the change list in BgpConfigListenerMock and
// trigger the BgpConfigManager to process the change list.
// 11. TearDown terminates BgpConfigManager and cleans up all IFMap state.
