TypeScript 2.0 & ts-node 1.3 support

[drinchev]

Hey all,

Thank you for your hard work.

Just wanted to report that it doesn't work with TS 2.0 & ts-node 1.3. It actually compiles properly but the source maps doesn't seem to load in the coverage html file.

Update :

I ended up using https://github.com/istanbuljs/nyc

  "scripts": {
    "test:unit": "mocha --compilers ts:ts-node/register \"test/**/*.ts\"",
    "test": "nyc -e '.ts' --r html -r lcov -r text npm run test:unit",
    "build": "tsc"
  }

Credits for that goes to http://rundef.com/typescript-code-coverage-istanbul-nyc

This is a bit odd. I have a project that runs fine with typescript 2.0.3 and ts-node 1.4.3, albeit using jasmine.

So I suspect this issue can be resolved without nyc...

@drinchev do you have a project I can clone to see the error?

[mummybot]

FYI I didn't have the issue exactly as @drinchev stated, rather I hardly have any globally loaded node modules, and found the types setting in the example didn't reflect typescript 2+. Then using nyc (as the cmd line for Istanbul) it worked a treat.

By the way @mummybot, thanks for the PR. Would be interesting to hear your thoughts on gotwarlost/istanbul#212 (comment)

[drinchev]

@Izhaki unfortunately it would be hard to recreate the issue in a test project so late.

I think switching to nyc brings more benefits as well.

Thank you all!

I wanted to add code coverage to an OSS I'm contributing that's written in Typescript. My first choice was istanbul, but having to also use remap-istanbul. to produce the desired result was a cons. Then I tried nyc and never looked back.

[Izhaki]

So far, nyc prevails as the clear winner to this problem. That much I acknowledge. To be frank, although I'm yet to try it, I'm pretty sure I'll opt for it next based on the raving reviews.

I'm still trying to establish what is the relationship between Istanbul and nyc, and it is rather odd nobody seems to have an answer!

Thank you for all your effort!. I am newbie here. I am trying to run this as is, I get following error - when I execute npm run test:coverage. Is there anything I am missing here. Appreciate your help.
