Test dialogs independently

[ihachani]

Is there a way to test Library without having to create a bot around it?

No, the framework requires a bot through which it can send and receive messages. You can make a simple bot that allows full logical and code coverage for your library though and test through that.

Can some one add this? That would save some effort.

Now that you mention it, this seems like it may be a useful feature. It would also be cool to setup mock data to preload with. So something like

new BotTester(bot)
    .WithDialog(dialog, <something here to set mock state when dialog starts>)
    .WithMiddleware(middleware)

Would you be interested in helping design the feature &/or the implementation?

What I did to test the library was create a Bot then mapped the library default Dialog to the bot default Dialog.

let bot = new botbuilder.UniversalBot(new TestConnector());
let library = CustomLibrary.createLibrary();
bot.library(library);
bot.dialog('/', library.dialog('/'));

I am thinking something like this will be helpful:

new BotTester(bot)
    .WithDialog(['/',library.dialog('/')],['greeting', anotherDialog]);

I think that would be a great addition. Would you be interested in being a contributor? It will help shape the library towards your needs.

I will give it a try. Do you have some guidelines?

• follow the linter as closely as you can
• tests that prove the new code works
  • this means failure and success cases
• new features, such as this, should be included in the BotTester.mocha.spec.ts and include proper decorations as can be seen in the file to easily update the README.md
• add the new test to the README
• PRs should be made to the dev branch
