Running Windows PowerShell during test execution

Here's an example,

function PSTest()
{
    var oShell = getActiveXObject("WScript.Shell");
    var oExec = oShell.Exec("powershell -Command \"C:\\Temp\\HelloWorld.ps1\"");
    oExec.StdIn.Close(); // Close standard input before reading output

    // Get PowerShell output
    var strOutput = oExec.StdOut.ReadAll();
    // Trim leading and trailing empty lines
    strOutput = aqString.Trim(strOutput, aqString.stAll);

    // Post PowerShell output to the test log line by line
    aqString.ListSeparator = "\r\n";
    for (var i = 0; i < aqString.GetListLength(strOutput); i++)
    {
        Log.Message(aqString.GetListItem(strOutput, i));
    }
}

HelloWorld.ps1 contains just

Write-Host "Hello World"

Ensure your path is correct; use double backslash, and enclose the full path in quotes
