【问题描述】：
我似乎在为我的 NodeJS 应用程序设置单元测试然后使用 Jasmine 运行它们时遇到问题。问题在于使用 Jasmine 的 done 函数。每当我在测试中包含 done 函数时，我都会收到一条错误消息：Warning: Cannot read property 'clearTimeout' of undefined Use --force to continue. 我很确定我做的不对，但我仍然无法理解它到底是什么。
我的 Gruntfile.js：
module.exports = function(grunt){
// Load grunt tasks automatically
require('load-grunt-tasks')(grunt);
grunt.initConfig({
// Make sure code styles are up to par and there are no obvious mistakes
jshint: {
options: {
jshintrc: '.jshintrc'
},
all: [
'Gruntfile.js',
'app/scripts/Directives/**/*.js',
'app/scripts/Services/**/*.js',
'app/scripts/app.js'
]
},
// Empties folders to start fresh
clean: {
options: { force: true },
dist: {
files: [
{
dot: true,
src: [
'/dist/*'
]
}
]
},
coverage: {
files: [
{
dot: true,
src: [
'.coverage/'
]
}
]
}
},
// Copies remaining files to places other tasks can use
copy: {
dist: {
files: [
{
expand: true,
dot: true,
cwd: '<%= yeoman.app %>',
dest: '<%= yeoman.dist %>',
src: [
'*.{ico,png,txt,json,js,shtml,template}',
'images/{,*/}*.{webp}',
'fonts/*',
'images/**/*.svg',
'api-documentation/**/**/*',
'api-explorer/**/*',
'styles/*.{ttf,woff,svg,css}',
'docs/**/*',
'template/**/*.{htm,html}',
'locale/*',
'config/*'
],
rename: function(dest, src){
if(src.indexOf('customizations.html.template') !== -1 ||
src.indexOf('customizations.js.template') !== -1){
console.log( dest + '/' + src.replace('.template', ''));
return dest + '/' + src.replace('.template', '');
}
return dest + '/' + src;
}
},
{
expand: true,
cwd: '.tmp/images',
dest: '<%= yeoman.dist %>/images',
src: [
'generated/*'
]
},
{
expand:true,
cwd: '.tmp/styles',
dest: '<%= yeoman.dist %>/styles',
src:['customer.css']
}
]
}
},
// Test settings
karma: {
unit: {
configFile: 'karma.conf.js',
singleRun: true,
reporters: ['dots']
},

}
},

}
}
},

}
},

},
run_node:{
start:{
files:{src:['app/index.js']}
}
},
stop_node:{
stop:{
files:{src:['app/index.js']}
}
}
});
grunt.loadNpmTasks('grunt-jasmine-nodejs');
grunt.loadNpmTasks('grunt-nodemon');
grunt.loadNpmTasks('grunt-concurrent');
grunt.loadNpmTasks('grunt-run-node');
grunt.registerTask('test', [
'karma:unit'
]);
grunt.registerTask('coverage', [
'clean:coverage',
'karma:coverage',
'open:covReport'
]);
grunt.registerTask('nodeTests', ['concurrent:nodeTests']);
grunt.registerTask('testingNode', ['run_node', 'jasmine_nodejs', 'stop_node']);
//grunt.registerTask('karmaNode', ['run_node', 'karma:node', 'stop_node']);
};
有问题的测试套件：
var request = require('http');
describe('Node server', function(){
'use strict';
//http://www.randomjavascript.com/2012/12/using-jasmine-node-to-test-your-node.html
var serverUrl = 'http://127.0.0.1:2425';
it('should respond to /', function(done){
request.get(serverUrl, function(response){
expect(response.statusCode).toBe(200);
done();
});
});
});
显然，我已经尝试了几种不同的方法来让它发挥作用。通过 Karma 运行它们比它的价值更麻烦（我把那个配置留在那里以展示我尝试过的东西。）虽然我对 nodeMon 和 jasmine-nodejs 的输出感到满意，但我仍然无法得到整个事情从前到后运行，因为没有done 函数，事情就像你期望的那样挂起。它应该就在那里，但对我来说不是。我的 package.json 包含：
{
"name": "myProject",
"version": "0.0.1",
"dependencies":{},
"devDependencies": {
"karma": "~0.13",
"karma-coverage": "~0.5",

"jshint":"~2.9"
},
"engines": {
"node": ">=0.12.0"
},
"scripts": {
"global": "npm i karma-cli grunt-cli -g"
}
}
有人可以告诉我这个过程在哪里缺少它需要的东西吗？
