QTP中几个交换值的方法-自动化测试

最近自动化测试工具QTP做挺多,有些用到的方法拿出来一点点共享,也算自己沉淀一下。
首先一个,测试中可能需要将某些数据存放到全局空间中,这个全局空间我也说不好,就是能让多个Action都取到的地方吧。我目前了解到的:
1)可以存在Action内定义的变量中,作为参数传给下一个调用的Action。
比如:Action1定义两个参数(右击Action,选择Action Properties,在Parameters选项卡中设置。)
调用时在RunAction最后部分把要传的变量写进去就行。
在Action中用Parameter(“参数名”)就可以取出来了。
2)存储在自定义对象或变量中,由QTP的Environment进行引用。
这里找个我以前参考AdvanceQtp中文档自己写的类及实现。
Class OurExcel
Private bAleadyInit
'********************sub Class_Initialize begin**********************
Private Sub Class_Initialize
'check whether has a environment variable named Reference_counter.
'this variable is for storing the number of current reference to "One" object.
On Error Resume Next
bAlreadyInit = IsObject(Environment("Reference_counter"))
If Err.Number <> 0 Then Environment("Reference_counter")=0
On Error Goto 0
'When "new" operation happen, add the counter.
Environment("Reference_counter") = Environment("Reference_counter") + 1
'Using the feature of QTP, storing the "One" object into environment...
'The environment name is "Excel_Object".
'a. check whether the variable exist.
On Error Resume Next
bAlreadyInit = IsObject(Environment("Excel_Object"))
If Err.Number <> 0 Then bAlreadyInit = False 'Environment isn’t even initialized
On Error Goto 0
'b. check whether has it's contents.
If bAlreadyInit = True Then
If Environment("Excel_Object") is Nothing Then bAlreadyInit = False
End If
'c. If no object found, create.
If bAlreadyInit = False Then
'Msgbox "Constrction object."
Environment("Excel_Object") = CreateObject("Excel.Application")
End If
End Sub
'********************sub Class_Initialize End**********************
'*******************sub Class_Terminate Begin********
Private Sub Class_Terminate
'Msgbox "enter terminate"
Environment("Reference_counter") = Environment("Reference_counter") - 1
'If no more reference exist, close the excel and terminate the environment variable.
If Environment("Reference_counter") = 0 Then
msgbox "Closing excel process........."
Environment("Excel_Object").Quit
Environment("Excel_Object") = Nothing
Environment("Reference_counter") = Nothing
End If
End Sub
'*******************sub Class_Terminate End***********
'the function only for providing a demo....
Public Function GetSheetData(sFileName, SheetNumber, strRangeBegin, strRangeEnd)
With Environment("Excel_Object")
.Visible = False
Set bjWorkbook = .Workbooks.Open(sFileName) '"C:/temp/Branches.xls"
Set bjWorkSheet = objWorkbook.WorkSheets(SheetNumber)
Reporter.ReportEvent micDone, "Current range:"&strCurrentQueryRangeBegin, _
objWorkSheet.Range(strRangeBegin&":"&strRangeEnd).value
Set bjWorkbook = Nothing
Set bjWorkSheet = Nothing
End with
End Function
End Class
Set oExcelInstace1 = New OurExcel
oExcelInstace1.GetSheetData "C:/temp/Branches.xls", 1, "A200", "A200"
oExcelInstace1.GetSheetData "C:/temp/Branches.xls", 1, "A201", "A201"
Set oExcelInstace2 = New OurExcel
oExcelInstace2.GetSheetData "C:/temp/Branches.xls", 1, "A202", "A202"
oExcelInstace2.GetSheetData "C:/temp/Branches.xls", 1, "A203", "A203"
'with class's Class_Terminate method, you can call it using the following style....
'Notice:This behave will call destructor of your class.............
'If has reference exist, then you will find one excel process in your machine.
Set oExcelInstace1 = Nothing
Set oExcelInstace2 = Nothing
里面有两个Environment变量,一个Excel_Object,一个Reference_counter。我想尽力把这东西做的象COM,当然有很大很大差距。当初就是为了找个全局的地方放数据而已。
3)存储在QTP的GlobalTable中。
涉及2个函数。一个是写入到GlobalTalbe,另一个是从其读入。
Function setValue(strColName, strColValue)
On Error Resume Next
DataTable.Value(strColName, dtGlobalSheet) = strColValue
If Err.Number <> 0 Then DataTable.GlobalSheet.AddParameter strColName, strColValue
setValue = strColValue
End Function
Function getValue(strColName)
Dim outputTemp
On Error Resume Next
outputTemp = DataTable.Value(strColName, dtGlobalSheet)
If Err.Number <> 0 Then
getValueFromGS = ""
Exit Function
Else
getValue = outputTemp
End If
End Function
一般这个方法的实现,可能还要遍历列名来判断是否存在,这样如果变量很多肯定效率低。QTP对于DataTable取数的实现肯定也进行了遍历或Find这样的方法,所以任务尽量让QTP来解决比较好,比如随机数干脆就直接用RandomNumber对象而取代 vbscript的Randomize加Rnd。
