Karma + Jasmine测试未与Chrome一起运行，“已执行0，共0个错误”

Question

我正在尝试用茉莉花和业力测试我的项目angular 5，但它显示了此错误：

myProject\Front\src\app> ng test
Your global Angular CLI version (7.0.3) is greater than your local
version (1.7.4). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".

这是我的karma.conf.js：

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

        basePath: '',


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

        //plugin needed
        plugins: [

        ],


        // list of files / patterns to load in the browser
        files: [

        },

        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,

        autoWatch: true,

        browsers: ['Chrome'],


        // Continuous Integration mode

        singleRun: false,

        // Concurrency level

        concurrency: Infinity
    })
}

这是Google Chrome浏览器中的界面：

我只是一个初学者，我不确定这些信息是否足够。我尝试了很多找到的解决方案，但始终是同样的问题。有人能帮我吗？

Answer 1

这是由于不兼容较新版本的Chrome（不适用于我的70版本）和最新版本的茉莉花（3.3.0）。短期解决方法是将您的茉莉花核心版本锁定为3.2.0。
