Testing still failing

[rajinder-yadav]

On Linux I am seeing this error:

Error: Cannot find module 'jsdom'  

If I correct mocha.shim.js by this

var jsdom = require('jsdom-no-contextify')

I see a failing test

I confirm. jsdom is missing.

    "js-dom": "^0.0.1",
    "jsdom": "^9.9.1",

After cleaning node_modules & running npm install again, I have

TypeError: Unable to require `.d.ts` file.
This is usually the result of a faulty configuration or import

Stranger things.

[nchanged]

I have added jsdom + travis. Let's keep pushing guys! Thanks a lot!

[nchanged]

The tests don't exit and travis can't just figure it out ... Any idea?

[rajinder-yadav]

@ojacquemart jsdom has a problem on Linux, with respect to contextify, I was getting errors. So I submitted a fix, seem like someone reverted back to require jsdom in mocha.shim.js?

See Issue: https://github.com/fuse-box/angular2-example/issues/13 and PR: https://github.com/fuse-box/angular2-example/pull/16/files

[ojacquemart]

@rajinder-yadav I am on linux too. No probs with jsdom. If I switch to jsdom-no-contextify in the mocha-shim file, I got the following error:

  1) TodoListComponent calls service to get todos:
     Error: Error in ./TodoListComponent class TodoListComponent - inline template:16:60 caused by: Cannot read property 'add' of undefined
      at ViewWrappedError.Error (native)
      at ViewWrappedError.ZoneAwareError (/home/olivier/dev/workspaces/angular2/angular2-example/node_modules/zone.js/dist/zone.js:958:33)

My node version: 6.9.2

In fact, the tests pass on the master. I had a strange directory making it fail previously. I test

@nchanged We should add a specific script and a specifc mocha opts file, for travis.

Without the option --watch src/**/!(main)*.ts in the mocha.opts, the tests exit.

[rajinder-yadav]

@ojacquemart My node and npm are more recent, could be the reason I see errors?

~: $ node -v
v7.4.0
~: $ npm -v
4.2.0

---

[Update] Confirmed it's versioning issues. If I use the following version, everything works fire.

angular2-example: master$ node -v
v6.9.2
angular2-example: master$ npm -v
3.10.9

Not sure what should be done? either open bug with upstream or find a fix.

[rajinder-yadav]

I just updated to node 7.5.0 and the everything is workings off master, the test passing!

[ojacquemart]

No idea why it could fail on node 7.4. Great :+1:

[RPDeshaies]

I just downloaded the latest version and I'm still having issues

On Windows 7

[RPDeshaies]

But when I declare the variables, everything is OK :

declare const describe: any;
declare const it: any;

[devmondo]

@RPDeshaies maybe you need to place your tsconfig in the root of your application?

[ojacquemart]

@RPDeshaies Could you try to add "types": [ "node", "mocha", "chai" ] in the tsconfig.mocha.json?

[RPDeshaies]

@ojacquemart not working

@devmondo just tried and I'm still getting the errors
