在Daftmonk强大的Yeoman outrightmental/partybot-web.git on GitHub 生成器上构建这个开源应用程序 angular-fullstack 。
我一直在努力将我的技能包含在Node.js测试（本地和CI）期间看似热门的当代问题中进行MongoDB模拟。
我喜欢 Mocha 用于运行， Chai 用于断言。淘汰了许多早期的竞争者之后，我现在正在尝试使用 Mockgoose 来模仿Mongoose模型而不是MongoDB。
另请参阅我的开源 partybot-web CI on Travis
中与此问题相关的构建到目前为止，这个配置已经能够成功运行一些数据库操作，证明Mockgoose不是完全浪费时间。但是，这个“会话”表似乎很难过。
请参阅下面的示例本地执行（Ubuntu 12），让我知道是否有任何Node向导有一颗智慧之珠......
非常感谢！ -Nick

Node.js Express框架的“会话”模块正在请求“sessions”MongoDB集合：
Session.save (node_modules/express-session/session/session.js:63:25)
我一直在使用Mockgoose来模拟我的Mongoose包裹的MongoDB表.. 它完美地完成了它的工作。
问题是这个“会话”集合是直接在Express框架配置中指定的，没有实现Mongoose ：
// Persist sessions with mongoStore
app.use(express.session({
secret: 'angular-fullstack secret',
store: new mongoStore({
url: config.mongo.uri,
collection: 'sessions'
}, function () {
console.log("db connection open");
})
}));
我必须单独进行Express会话模拟！

并非所有Mongoose都已完全实现。但是，如果您可以添加一个显示此问题的测试用例，那么我通常会专注于在列表中的其他项目上实现该项目。

我刚遇到同样的问题 - 我的解决方案是使用express-session的memorystore选项（默认情况下没有指定其他选项），而不是mongodb。真的很快，我刚才这样做了：
if (process.env.NODE_ENV === 'test') {
app.use(session({ secret: config.sessionSecret }));
} else {
app.use(session({
secret: config.sessionSecret,
store: new mongoStore({
//db: db.connection.db,
mongoose_connection: db.connection,
collection: config.sessionCollection
})
}));
}
