mocha test runner failing

See original GitHub issue

Hi, I’m trying out the latest test feature on alm, and the console is reporting

MOCHA STDERR:   ...\node_modules\alm\src\server\workers\tested\runners\mochaInstrumenter.ts:9
import * as common from "./instrumenterCommon";     
^^^^^^                                              
SyntaxError: Unexpected token import                
    at Object.exports.runInThisContext (vm.js:76:16)

Error was reproduced on OS X as well as Windows 10, running Node 6.x.

$ npm list -g alm
`-- alm@2.0.2
$ typescript --init
$ typings init
$ typings install --global mocha
$ cat alm.json
{
  "tests": {
    "include": [
       "./tests/*.ts"
    ]
  }
}
$ cat tests/sample.ts                         
/// <reference path="../typings/index.d.ts" />

describe('simple test', () => {               
  it('adds 2 + 2', () => {                    
    throw 'bad stuff'                         
  })                                          
})

Thanks. Documenting this for someone like myself in the future - able to reproduce error executing

$ C:/Users/Chui/AppData/Roaming/npm/node_modules/alm/node_modules/mocha/bin/_mocha \
  --require C:/Users/Chui/AppData/Roaming/npm/node_modules/alm/node_modules/ts-node/register  \
  --require C:/Users/Chui/AppData/Roaming/npm/node_modules/alm/src/server/workers/tested/runners/mochaInstrumenter.ts \
  --reporter json --full-trace tests/sample.ts

It appears that ts-config shouldIgnore is skipping the compilation of .ts files because they occur in node_modules directory.

The following patch fixes the issue

mochaRunner.ts
-----
- var instrumentationPath = __dirname + '/mochaInstrumenter.ts';
+ var instrumentationPath = __dirname + '/mochaInstrumenter.js';
