sample tests where response is coming from https://www.luis.ai/

[ranjan-2209]

What are these test for https://github.com/Microsoft/BotBuilder/tree/master/CSharp/Tests/Microsoft.Bot.Sample.Tests?

1. To test Bot Framework, or

2. To test the bot that I have created.

I am asking this because SetupLuis is used in SimpleAlarmBotTests.cs, which is a method of LuisTestBase class. And the parameter to SetupLuis is SetupLuis<SimpleAlarmDialog>(luis, a => a.SetAlarm(null, null), 1.0, entityTitle, entityDate, entityTime);. So this is pretty much obvious that we are not sending the request to LUIS: Language Understanding Intelligent Service (beta) and the request and response is being mocked. Its like testing 2 + 2 = 4. Kindly explain.

Those tests are to validate that the alarm sample works properly, not to check anything about the LUIS service. It's good practice to mock external dependencies so that the unit tests can run quickly without non-deterministic failures due to network conditions, etc.
