　　下面我们要开始配置karam。

　　3. Karma + Jasmine配置
　　初始化karma配置文件karma.conf.js
~ D:workspacejavascriptkarma>karma init

Press tab to list possible options. Enter to move to the next question.
> no

Enter empty string to move to the next question.

　　安装集成包karma-jasmine
　　~ D:workspacejavascriptkarma>npm install karma-jasmine
　　4. 自动化单元测试
　　3步准备工作：
　　1. 创建源文件：用于实现某种业务逻辑的文件，是我们平时写的js脚本
　　2. 创建测试文件：符合jasmineAPI的测试js脚本
　　3. 修改karma.conf.js配置文件
　　1). 创建源文件：用于实现某种业务逻辑的文件，是我们平时写的js脚本
　　有一个需求，要实现单词倒写的功能。如：”ABCD” ==> “DCBA”
~ vi src.js
function reverse(name){
return name.split("").reverse().join("");
}
　　2). 创建测试文件：符合jasmineAPI的测试js脚本
describe("A suite of basic functions"， function() {
it("reverse word"，function(){
expect("DCBA").toEqual(reverse("ABCD"));
});
});
　　3). 修改karma.conf.js配置文件
　　我们这里需要修改：files和exclude变量
module.exports = function (config) {
config.set({
basePath: ''，
frameworks: ['jasmine']，
files: ['*.js']，
exclude: ['karma.conf.js']，
reporters: ['progress']，
port: 9876，
colors: true，
logLevel: config.LOG_INFO，
autoWatch: true，
browsers: ['Chrome']，
captureTimeout: 60000，
singleRun: false
});
};
　　启动karma
　　单元测试全自动执行
~ D:workspacejavascriptkarma>karma start karma.conf.js
