标题: 新手的疑问：如何在PETSHOP 4.0模式下进行单元测试
如题，我做了一个基于PETSHOP 4.0模式的项目，现在做单元测试的时候遇到了个问题：如果我要对BLL层进行单元测试的话，我应该怎么进行测试呢？
测试代码如下： BLL层：

      public System.Collections.Generic.IList<Water.Model.Company> GetCompanyByUserName(string userName)
      {
         IList<Company> companies = DataAccess.CreateCompanyDal().GetCompanyByUserName(userName);

         foreach (Company company in companies)
         {
            company.ParentCompanyName = GetCompanyByCompanyId(company.ParentCompanyId).CompanyName;
         }

         return companies;
      }

SQL层代码为：

public IList<Company> GetCompanyByUserName(string userName)
      {
         IList<Company> companys = new List<Company>();
         SqlParameter parm = new SqlParameter("@userName", userName);

         using (SqlDataReader rdr = (SqlHelper.ExecuteReader(SqlHelper.ConnectionStringLocalTransaction, CommandType.Text, SELECT_COMPANY_BY_USERNAME, parm)))
         {
            while (rdr.Read())
            {
                  Company company = new Company();
                  company.CompanyId = (int)rdr["CompanyId"];
                  company.CompanyName = rdr["CompanyName"].ToString();
                  company.Level = (int)rdr["Level"];
                  company.ParentCompanyId = (int)rdr["ParentCompanyId"];
                  companys.Add(company);

            }
         }
         return companys;
      }

   生成的测试代码模板为：

      /// <summary>
      ///GetCompanyByUserName (string) 的测试
      ///</summary>
      [TestMethod()]
      public void GetCompanyByUserNameTest ( )
      {
         CompanyBLL target = new CompanyBLL();

         string userName = null; // TODO: 初始化为适当的值

         System.Collections.Generic.IList<Water.Model.Company> expected = null;
         System.Collections.Generic.IList<Water.Model.Company> actual;

         actual = target.GetCompanyByUserName(userName);

         Assert.AreEqual(expected, actual, "Water.BLL.CompanyBLL.GetCompanyByUserName 未返回所需的值。");
         Assert.Inconclusive("验证此测试方法的正确性。");
      }

对于          string userName = null; // TODO: 初始化为适当的值

         System.Collections.Generic.IList<Water.Model.Company> expected = null;
这两行我应该怎么设置，请大家指教，谢谢~~
