### Question:
ConnectorBase extends Connector { public int hashCode() { return hashCode; } ConnectorBase(); void initialize(String               connectorInstanceId,
                           ConnectionProperties connectionProperties); String getConnectorInstanceId(); ConnectionProperties getConnection(); void initializeConnectedAssetProperties(ConnectedAssetProperties connectedAssetProperties); ConnectedAssetProperties getConnectedAssetProperties(String userId); void start(); void disconnect(); boolean isActive(); int hashCode(); @Override boolean equals(Object object); @Override String toString();  }### Answer:
@Test public void testHashCode() { assertTrue(new MockConnector().hashCode() != new MockConnector().hashCode()); }
