How to wait for batch file execution to be completed before continuing with rest of keyword tests

Hi,   I have a some keyword tests, but before they are executed, I need to run a batch file that gets the executable for my App. But the batch file execution time varies with different versions of...

    This works! It takes a parameter and test run resumes only after the batch file has completed it's execution.

     

    Sub Run_Build (Build_Version)

     

    dim shell, x, y, z

    x="C:\FolderA\FolderB\"

    y=x & "App_Name.bat "

    z=Project.Variables.Build_Version

    set shell=CreateObject("WScript.Shell")

    shell.run y + z, 1, true

     

    End sub

Not only do I need to wait for the batch file execution to complete, I also need to pass a variable to the bacth file from my calling keyword test.

 

I've tried the following but none of these are working:

Sys.OleObject("WScript.Shell").Exec("cmd /c """"C:\Folder1\Folder2\App_Name.bat"" versionInput=Build_Version""")

 

Call Sys.OleObject("WScript.Shell").Run("""C:\Folder1\Folder2\App_Name.bat"", 1, true")

Call Sys.OleObject("WScript.Shell").Run("""C:\Folder1\Folder2\App_Name.bat"" versionInput=Build_Version")

 

Appreciate if someone can help.

Is your batch file set up to parse input parameters correctly? No use passing them in if it's not set up to use them!

 

http://stackoverflow.com/questions/26551/how-to-pass-command-line-parameters-to-a-batch-file

 

And telling if it's complete? Depends what it does. If there is something on-screen you can watch for, use that. If you want to look into using exit codes (either reading them or using them within the batch script to trigger some sort of on-screen indicator), start reading here:

    Yes, the batch file reads my input correct and uses it to get the install files that I am looking for. I used ''TestedApps.AppName.Run' command and passed the parameter. This works correctly, but the problem is that while the batch file is still getting all the files, my test suite contines with the rest of the tests.

     

    I only want the rest of the tests to start, once the batch file execution is done. The amount of time required for this varies from 5 minutes to maybe 10 or more minutes. That is the reason I need a way to delay the rest of the tests from executing until this is finished first.

     

    The batch file also has a return code of 0 if it found all the install files correctly.

      Hi,

       

      This code snippet should help:

      ' Run the command and wait for completion
      CreateObject("WScript.Shell").Run AFileName, 1, True

       

      More info about used functions is available in MSDN.

        Thanks Alex!

         

        That code works to get my batch file started and waits for its completion before starting other tests.

         

        But when it starts, I need to enter something like the version number of the install files I am looking for. I would like to be able to pass that as a parameter as well, so that the batch file will use that and start it's execution without waiting for user to enter the version info.

         

        Wondering if there is a way to incorporate both passing a parameter to the called batch file as well as waiting for it to complete in the same line of code?
