Describe the bug

Can't successfully run all the tests for botbuilder-js.

To Reproduce

Steps to reproduce the behavior:

1. git clone https://github.com/microsoft/botbuilder-js.git
2. npm install --global lerna nyc mocha typescript@2.7.2 to install pre-reqs
3. npm i
4. npm run test

Then this spits out instead of running tests:

Also alternatively tried cloning again, and just following I tried following steps outlined in the "Building the SDK" article in the bb-js Wiki, but this gets you an error even earlier, since it tells you to clone, then run tests, but no installing step before that...

Expected behavior

For tests to successfully run when running npm run test on a newly cloned botbuilder-js repo.

I haven't touched this repo in like 6 months, so maybe there's a step that I'm forgetting and missing...? (Though to be fair, should be documented then if that's the case)

[Zerryth]

This command works from the root mocha "libraries\bot*\tests\**\*.test.js"

Per @stevengum it doesn't look like it's a mocha issue

Also updated the Wiki on Building the SDK to now not ask for those global installs

Possibly related: istanbuljs/nyc#1205

We're currently on "^11.x.y" so we're severely out of date with the latest major version of nyc

botbuilder-js/libraries/botbuilder/package.json

Line 38 in d449253

"nyc": "^11.4.1",

Per my request, @Zerryth updated the wiki to remove the heinous npm install --global ... step...

Thanks @Zerryth 👍
