Issue with Karma runner executing test cases

Question

I am developing an application which uses Karma as testing tool for executing test cases. The problem is when I try to execute test cases it isn't executing any tests rather it just stuck at a point. When I use this command

grunt test --force 

I am getting this result

Running "clean:server" (clean) task

Running "concurrent:test" (concurrent) task

Running "compass:dist" (compass) task

Running "compass:server" (compass) task

Done, without errors.

Running "connect:test" (connect) task
Warning: Arguments to path.resolve must be strings Used --force, continuing.

Running "karma:unit" (karma) task
INFO [karma]: Karma v0.10.10 server started at http://localhost:9876/

After that no progress, it just stuck here. Here is my karma.conf.js file

// Karma configuration

// base path, that will be used to resolve files and exclude
basePath = '';
 module.exports = function(config) {
   config.set({
     frameworks: ['jasmine']
   });
 };
// list of files / patterns to load in the browser
files = [
  'bower_components/angular/angular.min.js',
  'bower_components/angular-route/angular-route.js',
  'bower_components/angular-resource/angular-resource.js',
  'bower_components/angular-animate/angular-animate.js',
  'bower_components/angular-sanitize/angular-sanitize.js',
  'bower_components/ng-grid/lib/jquery-1.9.1.js',
  'bower_components/ng-grid/ng-grid-2.0.7.min.js',
  'bower_components/angular-mocks/angular-mocks.js',
  'bower_components/angular-bootstrap/ui-bootstrap.js',
  'bower_components/momentjs/moment.js',
  'bower_components/nprogress/nprogress.js',
  'bower_components/toastr/toastr.js',
  'app/*.js',
  'app/**/*.js',
  '../sinonjs/test.js'
];

// list of files to exclude
exclude = ['app/out.js'];

preprocessors = {
  'app/*.js': 'coverage',
  'app/**/*.js': 'coverage'
};

// test results reporter to use
// possible values: dots || progress || growl
// for test coverage2 
reporters = ['progress', 'coverage'];
coverageReporter = {
  type : 'html',
  dir : 'coverage/'
}

// test results reporter to use
// possible values: dots || progress || growl
//reporters = ['progress'];

// web server port
port = 8080;

// cli runner port
runnerPort = 9100;

// enable / disable colors in the output (reporters and logs)
colors = true;

// level of logging
// possible values: LOG_DISABLE || LOG_ERROR || LOG_WARN || LOG_INFO || LOG_DEBUG
//logLevel = LOG_INFO;

// enable / disable watching file and executing tests whenever any file changes
autoWatch = false;

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

// If browser does not capture in given timeout [ms], kill it
captureTimeout = 5000;

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

What might be the issue here?

When I added a logLevel configuration in my karma.conf.js file I got the following result

Running "clean:server" (clean) task

Running "concurrent:test" (concurrent) task

Running "compass:dist" (compass) task

Running "compass:server" (compass) task

Done, without errors.

Running "connect:test" (connect) task

I resolved it myself by wrapping up all the configuration settings under the module.exports function. Now my karma.conf.js file will look like this;

// Karma configuration

// base path, that will be used to resolve files and exclude

 module.exports = function(config) {
   config.set({
   basePath : '',
     frameworks: ['jasmine'],
     logLevel: config.LOG_INFO,
// list of files / patterns to load in the browser
files : [
  'bower_components/angular/angular.min.js',
  'bower_components/angular-route/angular-route.js',
  'bower_components/angular-resource/angular-resource.js',
  'bower_components/angular-animate/angular-animate.js',
  'bower_components/angular-sanitize/angular-sanitize.js',
  'bower_components/ng-grid/lib/jquery-1.9.1.js',
  'bower_components/ng-grid/ng-grid-2.0.7.min.js',
  'bower_components/angular-mocks/angular-mocks.js',
  'bower_components/angular-bootstrap/ui-bootstrap.js',
  'bower_components/momentjs/moment.js',
  'bower_components/nprogress/nprogress.js',
  'bower_components/toastr/toastr.js',
  'app/*.js',
  'app/**/*.js',
  '../sinonjs/test.js'
],

// list of files to exclude
exclude : ['app/out.js'],

preprocessors : {
  'app/*.js': 'coverage',
  'app/**/*.js': 'coverage',
},

// test results reporter to use
// possible values: dots || progress || growl
// for test coverage2 
reporters : ['progress', 'coverage'],
coverageReporter : {
  type : 'html',
  dir : 'coverage/'
},

// test results reporter to use
// possible values: dots || progress || growl
//reporters : ['progress'];

// web server port
port : 8080,

// cli runner port
runnerPort : 9100,

// enable / disable colors in the output (reporters and logs)
colors : true,

// level of logging
// possible values: LOG_DISABLE || LOG_ERROR || LOG_WARN || LOG_INFO || LOG_DEBUG
//logLevel : LOG_INFO;

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

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

// If browser does not capture in given timeout [ms], kill it
captureTimeout : 5000,

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

Now all the test cases are executing fine.
