Cannot find module '@angular/core/testing'

[wuesam]

I wanted to get started with unittesting my Ionic2 application and followed the instructions provided, but when I create my first unit test I get the following Errors:

•      Cannot find module '@angular/core/testing'
  

•      C:\Workspace\....\test is not a module
  

And when I start „npm test“ I get the following error:

•      Cannot find module 'reflect-metadata'
  

I would appreciate any help on what is going wrong here

Are you able to install and test this repo without any issues?

Point of data: I have cloned this repo yesterday, npm test worked for me, but I still got warnings about "Cannot find module '@angular/core/testing'" in Visual Studio Code. I am using latest Node.js (6.9.1).

[lathonez]

@samoncode can you paste the actual output of npm test please? I'm not interested in Visual Studio errors (if that is what those first ones are).

[lathonez]

Also please confirm whether or not you are able to clone and test this repo.

We have no references to reflect-metadata anywhere in the project.

[wuesam]

@lathonez the first mentioned errors come from Visual Studio Code.
If I run "npm test" on this repo I get the following output

D:\Workspace\ionic2\clicker-master\clicker-master>npm test

"ionic serve" does not work for me here. Is this the expected behaviour?

Are you able to follow the Ionic tutorial?

http://ionicframework.com/docs/v2/getting-started/tutorial/

ionic start MyIonic2Project tutorial --v2

cd MyIonic2Project

ionic serve

If not please raise with Ionic.

[wuesam]

I indeed had a problem in general. Had to update node. And now the project here works for me! Great!
But I am on another computer at the moment, have to see what the problem in the other project was about..

[wuesam]

Ok, for me it is the same now as for aeremin. The test are working! Only VS-Code does not find the testing module.

[lathonez]

Removing this line solves it:

https://github.com/lathonez/clicker/blob/master/tsconfig.json#L22

Not a complete solution however:

#159

[lathonez]

Annoyingly enough I can't replicate 159 as I don't have windows.
