karma安装踩坑实录一. 要注意npm包全局安装与本地安装的区别。二输入karma init在本地生成karma.

一. 要注意npm包全局安装与本地安装的区别。

如果安装在全局，成功后直接输入karma start；如果安装在本地，输入./node_modules/karma/bin/karma start

二输入karma init在本地生成karma.conf.js文件，进行karma的配置。

具体配置内容，参考官网。我们这里设置如下

// Karma configuration
// Generated on Wed Mar 28 2018 00:26:22 GMT+0800 (CST)
require('phantomjs-prebuilt').path = './node_modules/.bin/phantomjs';
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/api/**/*.js",
        "./test/api/**/*.spec.js"
    ],


    // list of files / patterns 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: false,


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


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

    // Concurrency level
    // how many browser should be started simultaneous
    concurrency: Infinity
  })
}
