使用Jasmine进行数据库集成测试

Question

我想确保在Jasmine集成测试后关闭与数据库的连接。这是我目前的 - 将确保数据库连接适当关闭吗？

"use strict"; 

describe("MyCtorFunction", function() { 

    describe("myMethod", function() { 
    var _db = null, 
     _testContext = null; 

    beforeEach(function() { 
     _testContext = {}; 
     new DbHelper().openConnection(function (err, dbConnection) { 
     if (err) { 
      throw err; 
     } 

     _db = dbConnection; 
     }); 

     waitsFor(function() { 
     return _db; 
     }, "establishing a connection to the database.", 5000); 
    }); 

    afterEach(function() { 
     waitsFor(function() { 
     return _testContext.assertions.callCount === 1; 
     }, "waiting for the assertions to be called.", 5000); 

     runs(function() { 
     if (_db) { 
      _db.close(); 
      _db = null; 
     } 
     }); 
    }); 

    it("should do something", function() { 
     runs(function() { 
     //arrange 
     _testContext.assertions = assertions; 
     spyOn(_testContext, "assertions").andCallThrough(); 

     //act (_testContext.assertions invoked as callback) 
     new MyCtorFunction(_db).myMethod(_testContext.assertions); 

     //assert 
     function assertions(err, config) { 
      expect(config).toNotBe(null); 
      //etc. 
     } 
     }); 
    }); 
    }); 
}); 

Answer 1

不，这是假设如下：

• 网络连接测试期间不会丢失
• 没有语法或引用错误的断言本身
• 没有bug在andCallThrough和myMethod
