non è in grado di eseguire il test dell'unità karma nel browser PhantomJS

Question

In grunt eseguiamo il test dell'unità in PhantomJs seguendo i seguenti metodi.

Ecco il file karma.conf.js.

// Karma configuration 
// Generated on Thu Apr 03 2014 13:44:39 GMT-0500 (Central Daylight Time) 

module.exports = function(config) { 
    config.set({ 

    // base path that will be used to resolve all patterns (eg. files, exclude) 
    basePath: '', 


    // frameworks to use 
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter 
    frameworks: ['jasmine'], 


    // list of files/patterns to load in the browser 
    files: [ 
     {pattern: 'dist/lib/jquery/dist/jquery.js', watched: false, served: true, included: true}, 
     {pattern: 'dist/lib/jasmine-jquery/lib/jasmine-jquery.js', watched: false, served: true, included: true}, 
     {pattern: 'dist/lib/angular/angular.js', watched: false, served: true, included: true}, 
     {pattern: 'dist/lib/angular-route/angular-route.min.js', watched: false, served: true, included: true}, 
     {pattern: 'dist/lib/angular-mocks/angular-mocks.js', watched: false, served: true, included: true}, 

     {pattern: 'dist/main.min.js', watched: false, served: true, included: true}, 

     {pattern: 'public/test/unit/**/*Spec.js', watched: false, served: true, included: true}, 

     // fixtures 
     {pattern: 'public/test/mock/**/*.json', watched: true, served: true, included: false} 
    ], 


    // list of files to exclude 
    exclude: [ 

    ], 


    // preprocess matching files before serving them to the browser 
    // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor 
    preprocessors: { 

    }, 


    // test results reporter to use 
    // possible values: 'dots', 'progress' 
    // available reporters: https://npmjs.org/browse/keyword/karma-reporter 
    reporters: ['progress', 'html', 'junit', 'story'], 

    htmlReporter: { 
     outputDir: 'build/unit-test/html-report', 
     templatePath: 'node_modules/karma-html-reporter/jasmine_template.html' 
    }, 

    junitReporter: { 
     outputFile: 'build/unit-test/junit-report/test-results.xml', 
     suite: '' 
    }, 

    // web server port 
    port: 9876, 


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


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


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


    // start these browsers 
    // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher 
    browsers: ['Chrome'], 

    // Continuous Integration mode 
    // if true, Karma captures browsers, runs the tests and exits 
    singleRun: false 
    }); 
    }; 

Esegui il comando "karma: unitTestDev", quindi ottieni i seguenti errori.

Running "karma:unitTestDev" (karma) task 
INFO [karma]: Karma v0.11.14 server started at http://localhost:9876/

Aborted due to warnings. 

Stiamo riscontrando un problema in Windows e Linux. In Mac, il karma esegue con successo i test su PhantomJS.

In Windows, se eseguiamo il test sopra nel browser Chrome, invece di PhantomJS, quindi karma esegue con successo tutti i test di unità.

Qui ci sono le dipendenze legate karma in Package.json

"phantomjs": "~1.9.7-3", 
"karma": "~0.12.3", 
"karma-chrome-launcher": "~0.1.3", 
"karma-jasmine": "~0.1.5", 
"karma-html-reporter": "~0.2.3", 
"karma-junit-reporter": "~0.2.1", 
"grunt-karma": "~0.8.2", 
"karma-phantomjs-launcher": "~0.1.3" 

Fammi sapere se ci sono qualsiasi problema noto nel karma o grugnito con PhantomJS.

Answer 1

C'è un problema con "Karma-phantomjs-launcher" v0.1.3. Cambialo in v0.1.4 e poi funziona bene.
