Writing verification scripts is easy, if you understand how the application interacts with running scripts and if you follow verification script syntax.
The main file with the text of the verification script must have extension .vse. It must be located in the subfolder ..\Scripts\VFScripts of the main folder. Some other files must be included in the main script file using the directive %include.
The following schema presents a common structure of a verification script. It is similar to the script template VSTemplate.vs_, which is included with VSE.
