我的 Karma 安装用于自动观看 - 当我保存 .js 文件时，它会重新运行测试。自从我做任何 JavaScript 以来已经有几个月了，现在我再次使用它，自动监视功能不起作用。这是我的 karma.conf:

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: [
          'jQuery/jquery-1.10.2.js',
          'jasmine/jasmine.js',
          'jasmine-jquery/jasmine-jquery.js',
          'Angular/angular.js',
          'Angular/angular-route.js',
          'Angular/angular-mocks.js',
          'Angular/angular-animate.min.js',
          'Angular/angular-sanitize.min.js',
          'Angular/angular-cache.min.js',
          'emcommon.js',
          'Moment/moment.js',
          'ViewModels/Common/*.js',
          'ViewModels/Settings/*.js',
          'Tests/Common/*.js',
          'Tests/Settings/*.js',
        ],

        // 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: {
            '../ViewModels/**/*.js': 'coverage'
        },


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

        coverageReporter: {
            type: 'html',
        },

        // 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: true,
        usePolling: true,


        // 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
    });
};

最佳答案

输出在哪里？

首先，我认为使用以下 CLI 选项查看运行的输出会有所帮助:

# add --single-run, or kill the process manually when finished.
karma start karma.conf.js --auto-watch --log-level debug > log.txt

karma: {
  options: {
    configFile: 'karma.conf.js'
  },
  watch: {
    background: false,
    singleRun: false
  }
}

module.exports = function(config) {
  config.set({
    frameworks: ['mocha'],
    basePath: '',
    files: [ /** redacted **/ ],
    urlRoot: '/base/app/',
    reporters: ['progress'],
    logLevel: config.LOG_INFO,
    browsers: ['PhantomJS'],
    singleRun: true
  });
};

karma start newconf.js --auto-watch

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine'],
    files: [
      'some_jasmine_spec.js',
    ],
    reporters: ['progress'],
    port: 9000,
    colors: true,
    logLevel: config.LOG_DEBUG,
    autoWatch: true,
    browsers: ['Chrome'],
    singleRun: false
  });
};

describe('dummy_test', function() {
  it('just runs', function() {
    expect(true).to.be.false;
  });
});

关于javascript - Karma --auto-watch 不再有效，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31428916/
