Sailjs测试模型

Question

我想为我在Sails.js中创建的模型编写一些测试。该模型如下图所示：

/** 
* Users 
* 
* @module  :: Model 
* @description :: A short summary of how this model works and what it represents. 
* @docs  :: http://sailsjs.org/#!documentation/models 
*/ 

var User = { 

    /** 
    * Attributes list for the user 
    * @type {Object} 
    */ 
    attributes: { 
    password:{ 
     type: 'string', 
     alphanumeric: true, 
     required: true, 
     minLength: 6 
    }, 
    firstName: { 
     type: 'string', 
     maxLength: 50, 
     minLength: 5, 
     required: true 
    }, 
    lastName:{ 
     type: 'string', 
     maxLength: 50, 
     minLength: 5, 
     required: true 
    }, 
    email: { 
     type: 'email', 
     unique: true, 
     required: true 
    } 
    }, 

    /** 
    * Function that hashes a password 
    * @param {Object} attrs - user attributes list 
    * @param {Function} next [description] 
    * @return {[type]}   [description] 
    */ 

    beforeCreate: function(attrs, next) { 
    var bcrypt = require('bcrypt'); 
    bcrypt.genSalt(10, function(err, salt) { 
     if (err) return next(err); 
     bcrypt.hash(attrs.password, salt, function(err, hash) { 
     if (err) return next(err); 

     attrs.password = hash; 
     next(); 
     }); 
    }); 
    } 

}; 

module.exports = User; 

我已经编写了测试如下所示：

var assert = require('assert') 
    , Sails = require('sails') 
    , barrels = require('barrels') 
    , fixtures; 

// Global before hook 
before(function (done) { 
    // Lift Sails with test database 
    Sails.lift({ 
    log: { 
     level: 'error' 
    }, 
    adapters: { 
     default: 'mongo' 
    } 
    }, function(err, sails) { 
    if (err) 
     return done(err); 
    // Load fixtures 
    barrels.populate(function(err) { 
     done(err, sails); 
    }); 
    // Save original objects in `fixtures` variable 
    fixtures = barrels.objects; 
    }); 
}); 

// Global after hook 
after(function (done) { 
    console.log(); 
    sails.lower(done); 
}); 

// User test 
describe('Users', function(done) { 
    it("should be able to create", function(done) { 
    Users.create({firstName: "johnny", lastName: "BeGood", email: "johnnybegood@example.com", password: "validpassword123"}, function(err, user) { 
     assert.notEqual(user, undefined); 
     done(); 
    }); 
    }); 

    it("should be able to destroy", function(done) { 
    Users.destroy({email: "johnnybegood@example.com"}, function(err) { 
     assert.equal(true, true); 
    }); 
    }); 
}); 

不过，我永远只能得到第一个测试通过，我收到如下所示的输出：

我很新在节点/帆写作测试。任何人都可以指出我在这种情况下做错了什么。我利用以下要点 https://gist.github.com/joukokar/57b14e034e41893407f0

如果您使用的是异步摩卡测试，你必须在最后调用回调（done();）：

it("should be able to destroy", function(done) { 
    Users.destroy({email: "johnnybegood@example.com"}, function(err) { 
    assert.equal(true, true); 

    done(); 
    }); 
}); 

另外，我想测试assert.ifError(err)，而不是assert.equal(true, true) （如果代码不去那里，你根本看不到断言，但这并不意味着你实际测试了这个案例）。
