Data-Driven Loop

I have created a Data-Driven loop to read a .csv file. For each record read, I want to use the data as a parameter for a TestedApp. I have tried many different things to no avail. Any suggestions? Thanks in advance!

OK... I see your problem. Change the line I've marked in bold

Data Driven Loop (I read 5 records in the csv file.For each loop

Run Code Snippet: TestedApps.WWCabinetDoorOrder.Params.ActiveParams.CommandLineParameters = KeywordTests.TransferOrders.Variables.LoopOrdersToTransfer.Value(0)

Run Code Snippet: TestedApps.WWCabinetDoorOrder.Run()

Note the parenthesis on the "Run" method. In my reproduction, if you don't have that, the application runs, but it doesn't use the parameters.

It helps if you tell us what you tried, what happened when you did that, and what you expected to happen instead.

What kind of TestedApps you are using? It differs for each type. like Java WebStart, Windows App

  Within the Data Loop, I run 2 code snippets.
  
  1. TestedApps.WWCabinetDoorOrder.Params.ActiveParams.CommandLineParameters = KeywordTests.TransferOrders.Variables.LoopOrdersToTransfer.Value()
  
  2. TestedApps.WWCabinetDoorOrder.Run
  
  It seems to be skipping #1, but executes #2 correctly for each record in the loop. The parameter is stored in the .csv file that is read in the loop. I just don't know how to load that parameter before executing #2.
  
  This is a visual studio .net desktop executable.
  
  Thanks

    You have this:
    
    KeywordTests.TransferOrders.Variables.LoopOrdersToTransfer.Value()
    
    But... value of what? When doing a loop like you're doing, the Value method has a parameter to indicate what column within the source data you want to obtain the value for. You're missing that parameter.
