Instead of hardcoding channels, connection points where used, these where defined in a configuration file Copyright Endevo 2002

Seqence file TEST { for each $Temp in {85,-30,-20,25} SetTemperatureApp(28) TcVcoFreqVsVtuneApp(33) } SendMailApp(47) [Settings.SetTemperatureApp(28)] TestPath=L:\__NEW__\2_Applications\Common\SetTemperatureApp.vi in.Temperature(° C)=$Temp [Settings.TcVcoFreqVsVtuneApp(33)] .... The sequence file had to be TEXT based and possible to write/modify with notepad. The sequence file where executed by a LabVIEW application I called ”ScriptRunner” Copyright Endevo 2002

Graphic sequence editor To make it easier to create text based sequence files, I developed a graphical user interface, Copyright Endevo 2002

GUI to configure input parameters to a test case (VI) This also shows how to connect a variable from the sequece to a input parameter Copyright Endevo 2002

Debugger The test cases had an build in debugger Copyright Endevo 2002
