让我们说我有一个项目,使用凉亭,咕噜,bowerify(与垫片),因为我非常喜欢开玩笑,我想测试它.在运行测试时,如何在世界上看到我的浏览器垫片模块.我使用grunt来启动npm test命令.
这是我的package.json文件.
"browser": {
"jquery": "./bower_components/jquery/dist/jquery.js",
"foundation": "./bower_components/foundation/js/foundation/foundation.js",
"fastclick": "./bower_components/fastclick/lib/fastclick.js",
"greensock-tm": "./bower_components/gsap/src/uncompressed/TweenMax.js",
"greensock-css": "./bower_components/gsap/src/uncompressed/plugins/CSSPlugin.js",
"greensock-time": "./bower_components/gsap/src/uncompressed/TimelineMax.js",
"scrollmagic": "./bower_components/ScrollMagic/js/jquery.scrollmagic.js",
"handlebars": "./bower_components/handlebars/handlebars.runtime.js"
},
"browserify-shim": {
"jquery": "$",
"greensock-css": "CSSPlugin",
"fastclick": "FastClick",
"greensock-tm": "TweenMax",
"greensock-time": "TimelineMax",
"scrollmagic": "ScrollMagic",
"foundation": "foundation",
"handlebars": "Handlebars"
},
"browserify": {
"transform": [
"browserify-shim"
]
},
现在,我在运行测试之前通过在我的grunt文件中执行此操作几乎可以解决这个问题.
grunt.registerTask("shimBowerForTests",function(){
var readJson = require('read-package-json');
var fs = require('fs');
var remapify = require('remapify');
readJson('./package.json', console.error, false, function (er, data) {
if (er) {
throw "There was an error reading the file";
}
var packages = data.browser;
var browserify = require('browserify');
for (var key in packages){
var b = browserify();
var wstream = fs.createWriteStream("devjs/test/modules/"+key+'.js');
b.add(packages[key]);
b.bundle().pipe(wstream);
}
});
});
和.
exec: {
jestTest: {
command: 'cp -r devjs/modules devjs/test/modules && npm test'
}
}
问题是使用browserify所以将浏览器的所有内容与我的设置相结合,我可以要求我这样的shimmed模块.
require(‘jquery’)//示例但是在jest cli中测试失败,因为他们可以找到模块,除非我以某种方式用./加前缀,如此需要(‘./ jquery’)
最佳答案 我猜你的问题是你只用凉亭安装了你的shimmed模块.如果你想让它们在node / jest中工作,你也必须用npm安装它们.然后确保Jest没有在node_modules目录中模拟任何东西,只要名称匹配,它就应该在那里找到所有必需的模块.
你在package.json中的Jest配置应如下所示:
"jest": {
"unmockedModulePathPatterns": [
"./node_modules"
]
}
然后只需下载所有依赖项.
npm install jquery --save-dev
