我头一次做测试，根本不会搞。我们的程序是Web程序，ASP.NET &nbsp; 2.0的，发现我用的VSTS中自带的NUint很好用，能自动生成测试代码，挺激动，一下子就把所有类中的方法都生成了测试代码，但是遇到两个很严重的问题： <BR><BR>1、测试一个数据库访问类时，自动生成的测试代码会自动实例化一个数据库访问类，DataAccess &nbsp; target &nbsp; = &nbsp; new &nbsp; DataAccess(); &nbsp; ，但是在获取数据库链接字符串target.DbConnection的时候，就会获取不到User &nbsp; Id、Password和Data &nbsp; Source，都是空的。因为这个网站需要登录后才能访问，并且数据库连接用的User &nbsp; Id、Password和Data &nbsp; Source是放在web.config里面的 &lt;appSettings&gt; 下面的，所以我感觉问题应该是自动生成的测试代码没有到web.config中获取此三项数值所致。现在我怎么才能让自动生成的代码能跟web.config关联上以便获取到相应的值？ <BR><BR>怕说不明白，特附代码如下： <BR>自动生成的测试代码： <BR>[TestMethod()] <BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; public &nbsp; void &nbsp; getDataTableTest() <BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { <BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; DataAccess &nbsp; target &nbsp; = &nbsp; new &nbsp; DataAccess(); <BR><BR>string &nbsp; conn=target.DbConnection; &nbsp; ///这句话是我自己加的，此处有断点，目的是测试是否能获取到正确的User &nbsp; Id、Password和Data &nbsp; Source，这里过不去，下面的target.getDataTable(strSql)就肯定跑不过去了。 <BR><BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; string &nbsp; strSql &nbsp; = &nbsp; "select &nbsp; count(yhm) &nbsp; from &nbsp; yhdlrz &nbsp; where &nbsp; yhm= 'dfsh ' "; &nbsp; // &nbsp; TODO: &nbsp; 初始化为适当的值 <BR><BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; DataTable &nbsp; expected &nbsp; = &nbsp; null; <BR><BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; DataTable &nbsp; actual; <BR><BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; actual &nbsp; = &nbsp; target.getDataTable(strSql); <BR><BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Assert.AreEqual(expected, &nbsp; actual, &nbsp; "DoubleFox.DAL.DataAccess.getDataTable &nbsp; 未返回所需的值。 "); <BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Assert.Inconclusive( "验证此测试方法的正确性。 "); <BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } <BR>注：预期结果值expected &nbsp; 我已经构造好了，现在就是他自动实例化的target中，target.DbConnection获取不到值。下面是DataAccess类的相关代码： <BR><BR>/// &nbsp; 数据库连接类，负责建立数据库连接和对数据的一些访问操作 <BR>public &nbsp; class &nbsp; DataAccess <BR>{ <BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; public &nbsp; OracleConnection &nbsp; DbConnection <BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { <BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; get <BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { <BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return &nbsp; getOracleConnection(); <BR>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &
