使用QTP检查页面中的基本异常

  分三个函数来处理:

  1. 执行函数

  Public Sub excep_OpUser()

  routingname = "企业用户输入-异常测试"

  ' 载入数据表数据的第2行

  GE_SetCurRow OppDataFile,"企业用户",2

  Dim objStr,oScript,i

  set objStr = CreateObject("Scripting.Dictionary")

  set oScript = CreateObject("Scripting.Dictionary")

  ‘ 根据数据表字段设置每个字段的QTP执行语句

  for i = 1 to DataTable.GetSheet("UserData").GetParameterCount

  if DataTable.GetSheet("UserData").GetParameter(i)="企业名称" Then _

  objStr.add DataTable.value(i,"UserData"),".WebEdit("opername").set "

  ...

  Next

  ‘ 调用异常数据生成函数,返回值保存在dictionary对象oScript中

  Gen_excepData(objStr,oScript)

  ‘ 依次对含异常策略的字段进行异常测试

  For i = 0 to oScript.Count-1

  Call OpUserSet(1,oScript(i))

  Next

  set objStr = Nothing

  set oScript = Nothing

  End Sub

  2. 异常数据生成函数

  Public Function Gen_excepData(byval dObj,byRef oScript)

  ‘ 异常值,正确值,异常类型,异常参数

  Dim errorValue,CorrectValue,expType,expPara

  Dim objName,scriptstr

  Dim i,j,expItem

  expItem = 0 ‘ 记录异常数

  Randomize

  for i = 1 to DataTable.GetSheet("UserData").GetParameterCount

  ‘ 第一行数据为默认正确数值

  CorrectValue = DataTable.GetSheet("UserData").GetParameter(i).ValueByRow(1)

  datatable.SetCurrentRow 2

  if Instr(Datatable.value(i,"UserData"),"exp@@")>0 Then

  objName = dObj.Item(Datatable.value(i,"UserData"))

  ‘ 同一字段多种异常策略的处理

  arr1 = split (Datatable.value(i,"UserData"),"|",-1,1)

  For j = 0 to Ubound(arr1)

  ‘ 获取异常类型和异常参数

  If RegExpTest("exp@@.{1,}\(.{1,}\)",arr1(j)) Then

  exptype = Mid(arr1(j),6,InStr(arr1(j),"(")-6)

  expPara = Mid(arr1(j),InStr(arr1(j),"(")+1,InStr(arr1(j),")")-InStr(arr1(j),"(")-1)

  Else

  expType = replace(arr1(j),"exp@@","")

  End If

  ‘ 不同策略对应的数据生成

  select Case expType

  Case "SpecialChar"

  errorValue = Replace(CorrectValue,Right(CorrectValue,1),"%")

  scriptstr = objName + chr (34) + errorValue + chr(34)

  expItem = expItem + 1

  oScript.add "excepData" & expItem,scriptstr

  errorValue = Replace(CorrectValue,Right(CorrectValue,1),"'")

  scriptstr = objName + chr (34) + errorValue + chr(34)

  expItem = expItem + 1

  oScript.add "excepData" & expItem,scriptstr

  errorValue = Replace(CorrectValue,Right(CorrectValue,1),"/")

  scriptstr = objName + chr (34) + errorValue + chr(34)

  expItem = expItem + 1

  oScript.add "excepData" & expItem,scriptstr

  errorValue = Replace(CorrectValue,Right(CorrectValue,1),":")

  scriptstr = objName + chr (34) + errorValue + chr(34)

  expItem = expItem + 1

  oScript.add "excepData" & expItem,scriptstr

  errorValue = Replace(CorrectValue,Right(CorrectValue,1),"*")

  scriptstr = objName + chr (34) + errorValue + chr(34)

  expItem = expItem + 1

  oScript.add "excepData" & expItem,scriptstr

  errorValue = Replace(CorrectValue,Right(CorrectValue,1),"&")

  expItem = expItem + 1

  oScript.add "excepData" & expItem,scriptstr

  errorValue = Replace(CorrectValue,Right(CorrectValue,1),"?")

  scriptstr = objName + chr (34) + errorValue + chr(34)

  expItem = expItem + 1

  oScript.add "excepData" & expItem,scriptstr

  errorValue = Replace(CorrectValue,Right(CorrectValue,1),"""")

  scriptstr = objName + chr (34) + errorValue + chr(34)

  expItem = expItem + 1

  oScript.add "excepData" & expItem,scriptstr

  For n = 1 to expPara+1-Len(CorrectValue)

  Next

  Case "Num"

  errorValue = Left(CorrectValue,Len(CorrectValue)-1) & chr(Int(26 * Rnd + 97))

  scriptstr = objName & chr(34) & errorValue & chr(34)

  expItem = expItem + 1

  oScript.add "excepData" & expItem,scriptstr

  Case "NumMax"

  Case "NumLenMax"

  errorValue = CorrectValue

  Dim n

  For n = 1 to expPara+1-Len(CorrectValue)

  errorValue = errorValue & chr(Int(10 * Rnd + 48))

  Next

  scriptstr = objName & chr(34) & errorValue & chr(34)

  expItem = expItem + 1

  oScript.add "excepData" & expItem,scriptstr

  Case "NumLenMin"

  errorValue = Left(CorrectValue,expPara-1)

  scriptstr = objName & chr(34) & errorValue & chr(34)

  Dim n,tmpStr

  tmpStr = ""

  For n = 1 to Len(expPara)

  errorValue = ""

  scriptstr = objName & chr(34) & errorValue & chr(34)

  expItem = expItem + 1

  oScript.add "excepData" & expItem,scriptstr

  End Select

  Next

  End If

  Next

  End Function

  3. 页面输入函数

  即相应的QTP录制执行脚本,输入默认正确数值后,将相应字段修改为异常数值后提交,再判断是否出现相应的异常提示。

  (函数省略)

  通过以上方法,可以完整覆盖页面输入的异常判断,减轻人工测试覆盖不足的问题。
