### Question:
ConnectorBase extends Connector { @Override public String toString() { return "ConnectorBase{" + "connectorInstanceId='" + connectorInstanceId + '\'' + ", connectionProperties=" + connectionProperties + ", connectedAssetProperties=" + connectedAssetProperties + ", isActive=" + isActive + ", hashCode=" + 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 testToString() { assertTrue(new MockConnector().toString().contains("ConnectorBase")); }
