Hi all,

I generated ruby profile for my test suite. In my profile i observed  
that 10% of my test time is taken by WIN32OLE#method\_missing. It was  
called 60077 times.

Can anyone please help me understand when and why it is getting called.  
Is there any way to optimize it ?

I’m using  
ruby 1.8.4  
watir 1.5.1.1192  
ruby-prof 0.7.3

I’m attaching my generated ruby graph profile.

Thanks,  
Sandeep

That is the way WIN32OLE work. All properties and methods pass through  
method\_missing.

The C code can be written with Ruby code like this:

def method\_missing(id,\*args)  
method = id.to\_s  
if method[-1] == ?=  
method = method[0…-2]  
return ole\_propertyput(method,args.first)  
else  
return ole\_invoke(method, args,  
DISPATCH\_METHOD|DISPATCH\_PROPERTYGET, false)  
end  
end
