string comName = "Alfreds Futterkiste";
CustomerDAO customerDAO = new CustomerDAO();
Customer found = customerDAO.FindCustomerByID(id);
Assert.That(found, Is.Not.Null);
Assert.That(found.CustomerID, Is.EqualTo(id));
Assert.That(found.CompanyName, Is.EqualTo(comName));
id = "AROUT";
comName = "Around the Horn";
found = customerDAO.FindCustomerByID(id);
Assert.That(found, Is.Not.Null);
Assert.That(found.CustomerID, Is.EqualTo(id));
Assert.That(found.CompanyName, Is.EqualTo(comName));
}
}
这段代码不能编译,因为并没有CustomerDAO这个类,所以得新增该类以及FindCustomerByID方法,而且上面的测试中已经包括了两个测试场景,现在可以直接写实现:
public class CustomerDAO
{
public Customer FindCustomerByID(string id)
{
using (NorthwindDataContext ctx = new NorthwindDataContext())
{
IQueryable customers = ctx.Customers.Where(c => c.CustomerID == id);
if (customers.Count() > 0)
return customers.Single();
else
return null;
}
}
}
运行一下该测试,通过!然后再将aspx.cs里面的代码进行改动使Web页面的测试通过
void btn_find_customer_Click(object sender, EventArgs e)
{
string id = tb_customerID.Text;
Customer c = customerDAO.FindCustomerByID(id);
if (c == null)
return;
lbl_customerID.Text = c.CustomerID;
lbl_companyName.Text = c.CompanyName;
pnl_customerInfo.Visible = true;
}
不错,现在第一部分功能已经完成了,所有测试已经通过了,这时候我们可以打开浏览器,试试查找Customer的功能。
回头看看刚才写的测试代码,有很多重复的地方,这是不好的,需要进行重构。这里也就不列出重构代码了。
到我们实现第二部分的时候了,列出该用户相关的所有Order。在这里也不再详细些步骤了,就放出测试代码,实现的话还是很容易的 :) 当然测试并不完全,需要更加完善。
web页面测试代码:
[Test]
public void ShouldFindOrders()
{
string id = "ALFKI";
ie.TextField(Find.ById("tb_customerID")).TypeText(id);
ie.Button(Find.ById("btn_find_customer")).Click();
ie.Button(Find.ById("btn_find_orders")).Click();
Table ordersTable = ie.Table(Find.ById("grdv_orders"));
Assert.That(ordersTable, Is.Not.Null);
Assert.That(ordersTable.TableRows.Length, Is.EqualTo(6 + 1));
}
DAO测试代码:
[TestFixture]
public class OrderDAOTests
{
[Test]
public void ShouldFindOrdersByCustomerID()
{
string id = "ALFKI";
OrderDAO orderDAO = new OrderDAO();
List orders = orderDAO.FindOrdersByCustomerID(id);
Assert.That(orders.Count, Is.EqualTo(6));
}
}
