问题描述
我设置了grunt来运行node.js茉莉花测试。出于某种原因,使用此配置,结果总是显示双倍的测试结果。
以下是我的配置:
我正在使用插入grunt的。
/spec/some-spec.js :
var myModule = require('../ src / myModule.js');
describe('test',function(){
it('works',function(done){
setTimeout(function(){
expect(1).toBe 1);
done();
},100);
});
});
Gruntfile.js :
module.exports = function(grunt){
grunt.initConfig({
jasmine_node:{
options:{
forceExit:true
},
all:['spec /']
}
});
grunt.loadNpmTasks('grunt-jasmine-node');
grunt.registerTask('default',['jasmine_node']);
};
这导致两次测试运行,而不是一次。

项目相当古老。最新的是从2014年7月开始的。插件看起来很活跃,但是针对一些陈旧的东西运行似乎毫无意义。恕我直言。
使用Jasmine测试CommonJS模块我推荐使用以及
和插件。我将你的例子用于以下文件:
package.json
private:true,
devDependencies:{
grunt:^ 0.4.5,
grunt-jasmine-node:^ 0.3.1,
grunt-karma:^ 0.10.1,
jasmine-core:^ 2.3.4,
karma:^ 0.12.31,
karma-commonjs:0.0.13,
karma-jasmine:^ 0.3.5,
karma-phantomjs-launcher:^ 0.1.4
}
}
karma.conf.js
module.exports = function(config){
config.set({
basePath:'。',
frameworks:['jasmine','commonjs'],
files:[{
pattern:'src /**/*.js'
},{
pattern:'spec / ** / *。js'
}],
预处理器:{
'src / ** / *。js':['commonjs'],
'spec / ** / *。js':['commonjs']
},
记者:[ '进度'],
浏览器:['PhantomJS']
});
};
Gruntfile.js (可选,如果您仍想使用grunt)
module.exports = function(grunt){
grunt.initConfig({
karma:{
单元:{
configFile:'karma.conf.js',
options:{
singleRun:true
}
}
}
});
grunt.loadNpmTasks('grunt-karma');
grunt.registerTask('default',['karma:unit']);
};
您应该也在全局安装karma命令行转义程序,就像您可能用grunt做的那样。 npm install -g karma-cli
在命令行中,您可以通过键入业力开始
。它将运行测试,然后观察文件并在每次保存时重新运行它们。 (非常好)
或者,你可以运行 karma start --single-run
来运行你的测试一次并退出。如果您还更新了Gruntfile,您也可以运行 grunt
来运行一次测试。
I set up grunt to run node.js jasmine tests. For some reason, with this config, the results always show double the tests.
Here is my config:
I'm using jasmine-node which plugs into grunt.
/spec/some-spec.js:
var myModule = require('../src/myModule.js');
describe('test', function(){
it('works', function(done){
setTimeout(function(){
expect(1).toBe(1);
done();
}, 100);
});
});
Gruntfile.js:
module.exports = function(grunt) {
grunt.initConfig({
jasmine_node: {
options: {
forceExit: true
},
all: ['spec/']
}
});
grunt.loadNpmTasks('grunt-jasmine-node');
grunt.registerTask('default', ['jasmine_node']);
};
This results in two tests running rather than one.
> grunt
Running "jasmine_node:all" (jasmine_node) task

The jasmine-node project is pretty old. The latest commit is from July of 2014. The grunt-jasmine-node plugin appears to be active, but running against something that is going stale seems a little pointless IMHO.
To test CommonJS modules using Jasmine I'd recommend using Karma along with thekarma-jasmine and karma-commonjs plugins. I got your example working with the following files:
package.json
{
"private": "true",
"devDependencies": {
"grunt": "^0.4.5",
"grunt-jasmine-node": "^0.3.1",
"grunt-karma": "^0.10.1",
"jasmine-core": "^2.3.4",
"karma": "^0.12.31",
"karma-commonjs": "0.0.13",
"karma-jasmine": "^0.3.5",
"karma-phantomjs-launcher": "^0.1.4"
}
}
karma.conf.js
module.exports = function(config) {
config.set({
basePath: '.',
frameworks: ['jasmine', 'commonjs'],
files: [{
pattern: 'src/**/*.js'
}, {
pattern: 'spec/**/*.js'
}],
preprocessors: {
'src/**/*.js': ['commonjs'],
'spec/**/*.js': ['commonjs']
},
reporters: ['progress'],
browsers: ['PhantomJS']
});
};
Gruntfile.js (optional if you still want to use grunt)
module.exports = function(grunt) {
grunt.initConfig({
karma: {
unit: {
configFile: 'karma.conf.js',
options: {
singleRun: true
}
}
}
});
grunt.loadNpmTasks('grunt-karma');
grunt.registerTask('default', ['karma:unit']);
};
You should also install the karma command line runner globally, just like you probably did with grunt. npm install -g karma-cli
From your command line you can start karma by typing karma start
. It will run the tests and then watch your files and re-run them on every save. (VERY NICE)
Alternatively you can run karma start --single-run
to have it just run your tests once and exit. If you also updated your Gruntfile you can also just run grunt
to run the tests once.
