warnings and errors with Karma/Chrome

Question

Just learning angularjs right now with the book 'AngularJS Up and Running' from O'Reilly.. Got to the chapter on unit testing with Karma & Jasmine, but having trouble making it work

EDIT: Changing logLevel to config.LOG_DEBUG now matches file patterns correctly. But I still have the ultimate 'adapter' error at the end.

running the 'karma start' command gives me the following:

  You need to include some adapter that implements __karma__.start method!

So first of all it has warnings finding files, however all of those files do exist at that location.

My karma.conf.js file looks like this:

module.exports = function(config) {
  config.set({
    // base path, that will be used to resolve files and exclude
    basePath: '',

    // testing framework to use (jasmine/mocha/qunit/...)
    frameworks: ['jasmine'],

    // list of files / patterns to load in the browser
    files: [
      'angular.min.js',
      'angular-mocks.js',
      'controller.js',
      'simpleSpec.js',
      'controllerSpec.js'
    ],

    // list of files / patterns to exclude
    exclude: [],

    // web server port
    port: 8080,

    // level of logging
    // possible values: LOG_DISABLE || LOG_ERROR ||
    //                  LOG_WARN || LOG_INFO || LOG_DEBUG
    logLevel: config.LOG_DEBUG,


    // enable / disable watching file and executing tests
    // whenever any file changes
    autoWatch: true,

    // Start these browsers, currently available:
    // - Chrome
    // - ChromeCanary
    // - Firefox
    // - Opera
    // - Safari (only Mac)
    // - PhantomJS
    // - IE (only Windows)
    browsers: ['Chrome'],


    // Continuous Integration mode
    // if true, it capture browsers, run tests and exit
    singleRun: false
  });
};

karma is installed in my project folder (where karma.conf.js is located)

I really have no idea what's wrong and I can't see a way to contact the author of this book. Thanks!

Have you installed [karma-chrome launcher](https://www.npmjs.org/package/karma-chrome-launcher) and [karma-jasmine](https://www.npmjs.org/package/karma-jasmine) ? — glepretre, Oct 31 '14 at 08:50
By the way, you should just pick one log level in the `logLevel` option. I suggest you to use `config.LOG_DEBUG` to have full log which could help you to understand what happens ;) — glepretre, Oct 31 '14 at 08:53
Interesting I changed it to LOG_DEBUG and now the 'missing' files are found, but I still get the error about including an adapter. Edited post. — Richard Lovejoy, Oct 31 '14 at 15:50
Yes I've seen it but it doesn't help me. For me it seems karma can't attach to the jasmine adapter for whatever reason. I don't have a package.json but the book doesn't mention needing one. — Richard Lovejoy, Oct 31 '14 at 17:25

I was facing that same issue and my mind was about to explode. I couldn't find anything anywhere, all the configurations were ok and nothing seemed wrong. Your question was the closest thing I could find.

I realized that both, your project filepath and mine contained square braces (.../[lab]/... in yours) and that it might be the cause. It is known that special caracters sometimes are troublesome.

I deleted the square braces from my filepath and all the tests worked perfectly.

If you pay attention to the Debug lines, jasmine.js and adapter.js were not resolved.

I hope this could be of some help.

Thank you, it did help me. I have a invalid character in my files path too! – Rajiv Jan 11 '16 at 10:54
You could try using a escape character, such as "\[" and "\]" – Bernardo Dal Corno Apr 10 '18 at 19:02
