[Windmill-dev] PHPUnit integration

[Mikeal Rogers]

Actually our tinderbox work isn't in perl at all. Tinderbox simply  
runs a command line windmill which pulls in JSON or XMLRPC based  
tests and spits out some text that tinderbox can parse about the  
results.

I haven't used PHPUnit too much so I'm not that clear on the  
specifics and what it might require to integrate.

I'll spend some time this week writing up the documentation for what  
it takes to implement your own test authoring library the same way  
we've authored the the python test writing library (which we're now  
trying to refer to as wmpython, as we expect alternative  
implementations in python as well).

If you just want to have your PHPUnit framework run a single command  
line and parse the output, you could use the tinderbox option we have  
and keep your tests in either JSON or Python.

If you do decide to write a new test authoring library there is one  
large issue that you should be aware of that I've been meaning to  
document. The issue is that the XMLRPC dispatcher we use is from the  
python stdlib SimpleXMLRPCServer (I just wrote a WSGI app that wraps  
it, wsgi_xmlrpc). This doesn't support dynamic assignment or  
recursive attribute lookup for resolving and running dispatched  
methods. Since the windmill service doesn't know what controller  
methods the IDE implements until it comes up (this is so that we keep  
everything dynamic and extensions can benefit from first class  
support) you have to do send each callback object to execute_test or  
execute_command, rather than just being able to call them outright  
like regular RPC methods.

If you take a look at http://windmill.osafoundation.org/trac/browser/ 
windmill/trunk/windmill/authoring/__init__.py you'll see how I need  
to call getControllerMethods and then dynamically assign a wrapped  
method to the test client instance. This is a huge barrier for anyone  
who's trying to write an authoring library right now, and most likely  
makes it near impossible to write a good library in a statically  
typed language.

For windmill 0.3 I'll be writing a new xmlrpc library ( which will  
actually be available independently of windmill as a normal wsgi  
application ) which supports dynamic assignment and recursive  
attribute lookup for resolving and running dispatched methods, and  
will probably use cElementTree and be much faster than the current  
dispatcher. For right now tho, we have what we have.

Hope this helps.
