Karma error - Unknown provider: $$asyncCallbackProvider

Question

Trying to run my karma test through grunt but getting an error:

Error: [$injector:modulerr] Failed to instantiate module ngMock due to:
Error: [$injector:unp         


        

Answer 1

You should add all the angular dependencies that you used in your project to your karma.conf.js file. It seems like you need to add ngMock to your karma file, like the example below :

    files: [
         '*/**/angula-ngMock.js'
    ],

Answer 2

I had the same problem just now, and fixed it by making sure the version of my angular-mock dependancy was the same as that angular.

You can do this in your bower.json file (change "angular-mocks": "~1.3.0" to "angular-mocks": "^1.3.0" or a specific version).

Answer 3

While I have no doubt that 3sdmx's answer would work, I just ran an NPM update and that worked. Thought I should mention that so that people aren't maintaining their .json files so closely.
