日渐感觉测试的重要性，不仅保证产品的质量，对以后重构提供保障

Karma的安装就不说了

npm install -g karma-cli

npm install -g karma

配置文件应放在根目录下

实例

describe("A spec (with setup and tear-down)", function() {
    var foo;

    beforeEach(function() {
        foo = 0;
        foo += 1;
    });

    afterEach(function() {
        foo = 0;
    });

    it("is just a function, so it can contain any code", function() {
        expect(foo).toEqual(1);
    });

    it("can have more than one expectation", function() {
        expect(foo).toEqual(1);
        expect(true).toEqual(true);
    });
});

运行

karma start karma.config.js
