How to use the botbuilder-azure.AzureTableClient function in botbuilder-azure

beforeEach(() => {
    app = new VoxaApp({ views, variables });
    azureTableClient = new azure.AzureTableClient();
    storage = new azure.AzureBotStorage({ gzipData: false }, azureTableClient);

    // we need to mock this before instantiating the platforms cause otherwise
    // we try to get the authorization token

    adapter = new BotFrameworkPlatform(app, { recognizer, storage });
    simple.mock(storage, 'getData')
      .callbackWith(null, {});

    simple.mock(storage, 'saveData')
      .callbackWith(null, {});

    simple.mock(adapter, 'botApiRequest')
      .resolveWith(true);
  });

}

// Graph
var graph = {};

// Listen for messages from users
