/**
 * This is the official ConnectionService for Telecom's CTS App. Since telecom requires that a
 * CS be registered in the AndroidManifest.xml file, we have to have a single implementation
 * of a CS and this is it. To test specific CS behavior, tests will implement their own CS and
 * tell CtsConnectionService to forward any method invocations to that test's implementation.
 * This is set up using {@link #setUp} and should be cleaned up before the end of the test using
 * {@link #tearDown}.
 *
 * sConnectionService: Contains the connection service object provided by the current test in
 *                     progress. We use this object to forward any communication received from the
 *                     Telecom framework to the test connection service.
 * sTelecomConnectionService: Contains the connection service object registered to the Telecom
 *                            framework. We use this object to forward any communication from the
 *                            test connection service to the Telecom framework. After Telecom
 *                            binds to CtsConnectionService, this is set to be the instance of
 *                            CtsConnectionService created by the framework after Telecom binds.
