DCR: As a developer, I would like to see a good example that shows me how to write effective unit tests for conversations

Issue

The BotBuilder Samples repo doesn't include any examples on how to test a bot, it would be nice to have a Test Project for the non trivial bots so developers can see a test project in action.

Proposed change

Imlement unit test project for the CoreBot

The unit tests should show case how to:

• Use Dependency Injection to swap different components of the bot solution with mock objects
• Create mock objects for LUIS
• Use the testing framework and related tools for implementing tests
• How to unit test custom dialogs and custom prompts
• How to unit test controller code
• How to manage State for unit tests without having to rely on CosmosDB (MemoryState)
• Use test transcripts for review the test outcomes

Hi @Kaiqb, can you take a look at the list of samples above and provide some feedback on which ones makes sense to include in the list based on the BF documentation?
