Hi,

I'm experiencing the same issue -> fresh node and angular-cli installation, everything works, just the ng test doesn't (same error message and no karma plugin found).

angular-cli: 1.0.0-beta.18
node: 6.9.1
os: win32 x64

Cheers

Hi,

I'm experiencing the same issue.

angular-cli: 1.0.0-beta.16
node: 6.6.0
os: Linux x64

[Caballerog]

I found my error which was that I had not provider a service. This service is used in the component that I want to test.

[filipesilva]

Does this still happen with angular-cli@latest? I couldn't repro myself, and the symptoms seem to be of a broken install.

[Caballerog]

In my particular case, this error don't happen.

[filipesilva]

Closing as inactive.

Check if angular-cli/plugins/karma exists in the node_modules directory.

In my case the problem was that I had migrated to @angular/cli package, but karma.conf.js was still referencing the angular-cli paths. I updated my references by comparing to the karma.conf.js from this repo: https://github.com/angular/angular-cli/blob/master/packages/%40angular/cli/blueprints/ng2/files/karma.conf.js

[ahelord]

@juhap this work for me but in the karma.conf.js have issue
Error: No provider for "framework:angular-cli"! (Resolving: framework:angular-cli)

[sjcetx]

@ahelord check the answer provided by @juhap there are multiple locations that angular-cli needs to be changed to @angular/cli

[frankpiva]

@juhap It seems that your link is broken. Could you take a look and fix it please? I'm also having a similar issue.

@frank-productops New link you can check out: https://github.com/angular/angular-cli/blob/b15d1f37b6c6d7e57d969359b8b7d8a916465362/packages/%40angular/cli/blueprints/ng/files/karma.conf.js

[ahelord]

Hi,
When I updated from angular-cli to @angular/cli, i also faced the same issue:
Error: Cannot find module 'angular-cli/plugins/karma'

The solution worked for me is to update the karma.conf.js file present in root folder of the project.

frameworks: ['jasmine', '@angular/cli'],
...
plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-remap-istanbul'),
      require('@angular/cli/plugins/karma')
    ],
...
preprocessors: {
      './src/test.ts': ['@angular/cli']
    },
...

After this change, ng test should work.
