Here's an updated script and code to process the script. I made the script
syntax more friendly.
New example script...
==========
Check recipeListCount is 0
Do new
Check name is "New Recipe"
Keyin "PB&J" to name
Ch eck name is "PB&J"
Do save
Do close
Check recipeListCount is 1
Do goToListItem 1
Do openListItem
Check name is "PB&J"
==========
New Python code for test runner including skeleton of application model that
can be tested, but can't pass the tests...
