I would like to know if there is any way to know how much time my  
classes and methods are running. I would like to improve it running the  
test cases faster so I need to know which ones should be the first to  
improve.

So… my question is… how can I know the running time for every single  
method and class? I mean without including in every method a log at the  
beginning and end since I have hundreds of them.

Thanks in advance.

I would say: thats highly dependant on the operating system you use.  
For example,  
on OS X and Solaris, I would suggest to use dtrace for such a task.

Run the script you’re interested in tracing with -rprofile

ruby -rprofile how\_long\_does\_this\_stuff\_take.rb

Thanks a lot  
Is there any Eclipse plug-in that can do the same?
