TestComplete IronPython Sample
As part of an architectural prototyping phase I wrote a couple of IronPython wrapping classes around the C# .Net var/VarDelegate class.
Totally unsupported, but worth noting for anyone who wants to care.
These two helper classes let me successfully run the C# Order_JS test script and the Hello mspaint JavaScript tests when translated into Pythonese. (i.e. change true to True, etc...)
This way the syntax in a .Net environment is more like the syntax in JavaScript and you don't have to worry about TestComplete's problem with dying when an exception hits a JavaScript file sandbox boundary.
The IronPython debugging experience is where this approach fell apart for me. It seemed like the TestComplete COM interaction timed out on me or something while I was debugging in Visual Studio. But a print/Log.* based debug model worked well enough for me to write these classes.
The only line of code I had to change from the C# Orders_JS script file was the setting of the .Net property using ".Text" to calling the setter method "set_Text" directly like other parts of the JavaScript file did.
NOTE: No attempt was made to add * methods for ALL numerical operations. Just the ones necessary to make the ported test scripts happy. Fortunately as you can see the pattern is fairly straightforward.
NOTE2: Setting a value via Python [] notiation is not yet implemented.
NOTE3: var.VarDelegate's static dlgtsForCall seems manifestly unsafe from a threading perspective. YUCK.
The two classes involved are:
- TestComplete: This exposes the TC globals as properties and also exposes the usual RunTest/StopTest methods.
- WrappedObj: This wraps the .Net "var/var.VarDelegate" classes with a Python friendly syntax.
There is also a WrappedCollection object that I don't think is necessary any longer since WrappedObj supports all of the necessary operations.
