Code coverage on a live application

[lethal.possum]

Hello,

I would like to find unused code in an application while it is
running. I know tools like Clover but I've only used it with JUnit to
test the code coverage of my tests.

But this time the application is a client and I can't create unit
tests to simulate all the possible user actions and the server's
responses. So I'd like to monitor what lines of the code are executed
while real users use the application.

I can compile my application with debugging information so this it
should theoretically be possible to do this. I just don't know if
there is any tool to do it. Hopefully one of you already had the same
idea.

Thanks in advance for your help,

Thomas

Launching JUnit tests is not different from launching a Java
application. If you can instrument your code with Clover or Cobertura
and measure the code coverage of your tests, why couldn't you do the
same with your Java application?

Very good point, I should have thought of that!
I have been using Ant for so long that I'm forgetting the good old
command line sometimes

Thanks for reminding me,
