自动化测试实例：用QTP实现WEB页面链接扫描功能

时间：2010-07-20 来源：angelia_liu

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
