1、安装karma
安装时,需要提前安装node.js,才能执行下列步骤
打开命令行,把karma安装到系统里,加上
-g参数,使全局可用
npm install -g karma karma-cli
npm install -g karma-jasmine karma-chrome-launcher karma-firefox-launcher karma-ie-launcher karma-junit-reporter karma-commonjs karma-coverage karma-script-launcher
2、创建配置文件
打开netbeans,在项目配置文件夹下创建karma.conf.js文件
在IDE里,选中项目,右键--》新建--》karma配置文件
修改文件内容:
module.exports = function(config) {
config.set({
basePath: '../',
files: [
'public_html/js/*.js',
'test/js/*.js'
],
exclude: [
],
autoWatch: true,
frameworks: ['jasmine'
],
browsers: ['Chrome'
],
reporters: ['progress', 'junit'],
// the default configuration
junitReporter: {
outputFile: 'test-results.xml',
suite: ''
},
plugins: [
'karma-junit-reporter',
'karma-chrome-launcher',
'karma-firefox-launcher',
'karma-script-launcher',
'karma-jasmine'
]
});
};
创建测试文件
//路径public_html/js/plus.js
// Some code under test
function plus(a, b) {
return a + b;
}
//路径test/js/test.js
describe('plus', function() {
it('should pass', function() {
expect(true).toBe(true);
});
it('should work', function() {
expect(plus(1, 2)).toBe(3);
});
it('should work', function() {
expect(plus(5, 4)).toBe(2);
});
});
3、配置项目
选中项目--》右键属性--》JavaScript测试--》测试提供器karma
配置文件选中刚刚创建的karma.conf.js,确定关闭属性对话框。
4、运行测试项目
项目多了一个karma的图标,选中--》右键--》启动,即可进行项目测试。
5、异常,百撕不得骑姐~

完成。
按照官方的说明,配置N次,都不能成功执行。
恭喜你,和我的版本一样,是netbeans的bug
Product Version: NetBeans IDE 8.0 (Build 201403101706)
更新: NetBeans IDE 已更新到版本 NetBeans 8.0 Patch 1.1
Java: 1.7.0_45; Java HotSpot(TM) 64-Bit Server VM 24.45-b08
Runtime: Java(TM) SE Runtime Environment 1.7.0_45-b18
System: Windows 7 version 6.1 running on amd64; GBK; zh_CN (nb)
C:\Users>node --version
v0.10.22
C:\Users>karma --version
Karma version: 0.12.9
问题原因:
netbeans未能够识别出来karma.conf.js文件,给
C:\Users\consumer\AppData\Roaming\npm\karma.cmd 脚本传了个错误的启动参数
start "D:\Program Files\NetBeans 8.0\webcommon\karma\karma-netbeans.conf.js" --port 9880
根本没有加载我们的配置文件。
解决办法:
项目--》配置文件夹--》右键--》新建--》空文件--》karma.cmd
输入
karma start config\karma.conf.js
项目--》右键--》属性--》JavaScript单元测试--》karma--》浏览--》选中karma.cmd
--》确定
rock and roll~
start config\karma.conf.js

若控制台为乱码,修改netbeans的配置文件:
在NetBeans 8.0\etc\netbeans.conf文件里追加一行
netbeans_default_options="-J-Dfile.encoding=UTF-8"
