karma-runner - Karma 输出重复测试结果

Question

当运行测试 karma 似乎多次重复上一个测试时，重复测试的次数似乎取决于测试的数量和用于运行的浏览器。

如果只使用一个浏览器(PhantomJS 或 Chrome)进行一次测试，测试会显示两次，当使用两种浏览器时，同一个测试最多显示 6 次。

我已经在测试中添加了日志记录，每个浏览器的每个测试都会出现一次日志，所以大概测试运行的次数是正确的，但只是复制了显示的结果。

karma 配置文件

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: [
        '_test/test.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: {
    },


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


    // 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,


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


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

测试.js

describe('karma testing', function () {
    it('tests karma is working', function () {
        expect(true).toBe(true);
        console.log('test1');
    });
});

输出 1 浏览器 (Chrome)

我已经在安装和不安装 karma-cli 的情况下对此进行了测试，结果是一样的。

我环顾了堆栈溢出和谷歌，有些人似乎遇到了类似的问题，但没有有意义的答案。

我在尝试让美化器工作时遇到了类似的问题。

karma.conf 有几个选项，比如 autoWatch、浏览器、singleRun——对吧？其中有一个叫做client的属性。

客户端属性是一个具有自己的一些属性的对象。其目的是配置与测试客户端相关的设置，例如 Chrome。

客户端有一个名为 captureConsole 的属性。这默认为 true，这意味着浏览器中的任何控制台日志也会发送回您的 bash。因此，在默认情况下启用该功能后，我看到了 Chrome 的控制台日志记录和美化的 Tap 输出。

试试你的这个设置，看看它是否有帮助!

client: {
    captureConsole: false
},
