问题描述

如何为ASP.net中的Page_Load函数创建单元测试?

How can create a unit test for the the Page_Load function in ASP.net?

我在Visual Studio单元测试框架中使用构建.我想创建一个单元测试，以检查网页的元素及其值.

我了解硒及其在单元测试中的能力.

这是要测试WebPageControl.ascx.vb的网页:

This is the web Page to test WebPageControl.ascx.vb:

   Public Class WebPageControl
        Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
            TextBox.Visible = False
        End Sub
End Class

这是单元测试WebPageControlTest.vb:

This is the Unit test WebPageControlTest.vb:

Public Class WebPageControlTest
    Public Sub PageLoadTest()

        Dim target As WebPageControl_Accessor = New WebPageControl_Accessor() 
        Assert.IsFAlse(target.TextBox.Visible)
    End Sub
End Class

执行完此操作后，我仍然会出现错误

After I do this I still get an error

Test method RechargeTest.WebPageControlTest.PageLoadTest threw exception: System.NullReferenceException: Object reference not set to an instance of an object.

推荐答案

您可能将无法在ASP.NET运行时之外新建Page.

You're probably not going to be able to new up a Page outside of the ASP.NET runtime.

您可能想在ASP.NET下四处搜索MVP(模型-视图-演示器)模式.恕我直言，它使测试Web代码变得容易得多.本文是一个很好的起点:

You may want to google around for the MVP (Model-View-Presenter) pattern under ASP.NET. It makes testing web code a lot easier IMHO. This article is a good starting point:
