karma test runner not running any tests
Solution 1
Under karma.config.js
, set either singleRun
or autoWatch
to true
. In your case both of them are set to false, hence karma is not running the tests.
singleRun: If true, it captures browsers, runs tests and exits with 0 exit code (if all tests passed) or 1 exit code (if any test failed).
singleRun: true
autoWatch: Enable or disable watching files and executing the tests whenever one of these files changes. Incase you want to watch your files.
autoWatch: true
Solution 2
Simple but sometimes overlooked cause: ensure you don't have syntax or compilation errors.
If running a Karma test for JavaScript via your IDE, you may have a syntax error which doesn't appear when you run your tests. This leads to Karma issuing the message "no tests were found".
I ran it under WebStorm; the error appeared under the "Karma Server" tab, while the "No tests were found" message appeared under "Test Run" (both tabs under "Run" or "Debug" tool window).

I'm using karma with jasmine and followed online guide by installing using
npm install --save-dev karma
and other necessities
i ran
./node_modules/karma/bin/karma start
and
karma start karma.conf.js
which opened up a external chrome browser showing that karma is connected. I wrote a simple unit test for one my functions it seems its not running any tests at all
This is my karma config file.
// Karma configuration 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: [ 'app/assets/components/angular/angular.js', 'app/assets/components/angular-mocks/angular-mocks.js', 'app/assets/javascripts/**/**/*.js', 'spec/javascripts/**/*.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_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'], // Continuous Integration mode // if true, it capture browsers, run tests and exit singleRun: false }); };
my unit test
describe('Unit: AddMedicalService',function(){ beforeEach(module('DoctiblePreTreatment')); var ctrl, scope; beforeEach(inject(function($controller,$rootScope){ scope = $rootScope.$new(); ctrl = $controller('AddMedicalServiceModalCtrl',{ $scope: scope }); })); it('should create return true if var 1 is greater than var2 , false if other wise', function(){ var compare1 = function(){ var var1 = 1; var var2 = 0; return var1 > var2; } var compare2 = function(){ var var1 = 0; var var2 = 1; return var1 > var2; } expect(compare1).toBeTruthy(); expect(compare2).toBeFalsy(); }); });
the particular function in the controller im trying to test
(function() { app.controller('AddMedicalServiceModalCtrl',['ProviderMedicalService','Treatment','$scope','$modalInstance',function(ProviderMedicalService,Treatment,$scope,$modalInstance){ $scope.newTreatment = {} $scope.checkless = function(var1,var2){ var1 = parseInt(var1); var2 = parseInt(var2); if(var1 > var2){ return true; } else{ return false; } } }]); })();
what is displayed on the console when i run karma
INFO [karma]: Karma v0.12.21 server started at http://localhost:8080/ INFO [launcher]: Starting browser Chrome INFO [Chrome 36.0.1985 (Mac OS X 10.9.4)]: Connected on socket MkqZfXcO6iIX4Od23QEr with id 9498055
Additional info: I'm using angular-js with ruby on rails. I'm aware that there is the jasmine gem out there that can help me. But my boss insisted that we should try using karma to do our unit testing/E2E for anuglarjs portion and rspec for rails.
