Botbuilder-js: [BotBuilder] TestFlow class does not match C# counterpart

[VictorGrycuk]

Versions

What package version of the SDK are you using. botbuilder@^4.8.0
What nodejs version are you using v12.16.1
What browser version are you using
What os are you using Windows 10 Pro

Describe the bug

The JavaScript implementation of TestFlow does not offer the same capabilities of its C# implementation.

Attempting to implement some functionalities based on the C# implementation of TestFlow is not possible to use the JavaScript version, especially those that rely on the BotCallbackhandler since its missing from JavaScript.

To Reproduce

1. Clone BotBuilder-DotNet.
2. Navigate to /libraries/Microsoft.Bot.Builder/Adapters/
3. Open TestFlow.cs
4. Clone BotBuilder-JS.
5. Navigate to /libraries/botbuilder-core/src/
6. Open testAdapter.ts, scroll down to line 537.
7. Compare both implementations of TestFlow

Expected behavior

I expect TestFlow in JavaScript to use the same implementation as in C#.

TestFlow C# vs TestFlow JavaScript

Additional context

While migrating bot-solution from the botframework-solutions repository tests, we found that C# uses the callback's context to set the userProfileState, however, that is not possible to do it with the current implementation of TestFlow in JavaScript.

At the moment we rely on using TestAdapter, but neither uses the BotCallbackHandler.

Needing assistance on completing the TestFlow/TestAdapter tests. Set up time with @joshgummersall for help.

[stevkan]

An error in the build process, when attempting to build a local copy, has been a roadblock for several weeks. However, I have finally gotten around the issue and will be moving forward on finalizing development of this.

[joshgummersall]

Both the TestFlow and TestAdapter constructors provide a callback parameter, so this is resolved.
