自动化测试实例：用QTP实现WEB页面链接扫描功能

 

        该函数实现用QTP脚本检查任何一个网页所有链接是否有效的功能。实际上，QTP自带一个对WEB page里的链接进行检查的checkpoint，但是不能自定义扩展和编辑；这里Sincky演示一个自定义的函数，模拟某个网页的每个链接发送HTTP请求、再检查HTTP响应结果来实现对该网页所有链接进行正确性扫描的过程。代码请见：

' Name: CheckAllLinkReachable

' Summary: CheckAllLinkReachable

' Parameters:

'         strBrowser: browser name

'         strPage: page name

'         strURLPattern: URL pattern you wan't to check. such as: ^http.*

' Return: None

Function CheckAllLinkReachable(strBrowser, strPage, strURLPattern)

        Dim blnReachable

         blnReachable = True

         Set objXML = CreateObject("Msxml2.XMLHTTP")

        ' Get all link on the page

         Set objDes = Description.Create

         objDes("micclass").Value = "Link"

         Set objLinkList = Browser(strBrowser).Page(strPage).ChildObjects(objDes)

         For i = 0 To objLinkList.Count() - 1

                   ' Create XML HTTP Object

                   strURL = objLinkList(i).GetROProperty("href")

                   If RegExpTest(strURLPattern, strURL) Then

                            objXML.Open "POST", strURL, false

                            objXML.Send

                   '         msgbox objXML.responseText

                            print (objLinkList(i).GetROProperty("href") & " Ready State:" & objXML.readyState & " Status: " & objXML.status)

                            If objXML.status <> "200" Then

                                     blnReachable = False

                            End If

                            objXML.abort()            

                   End If

         Next

         Set objXML = Nothing

         CheckAllLinkReachable = blnReachable

End Function
