Testing javascript with Mocha - how can I use console.log to debug a test?

I am using the javascript test-runner "Mocha".

I have a test that is failing, so I would to debug it using console.log.

But when the tests are run, there is no output (only the test results from Mocha). It seems like Mocha has captured and suppressed my console.log output!

How can I get Mocha to show my output? (at for tests that fail)?

EDIT:

Huge apologies! — console.log does work during tests! I must have been expecting it to suppress the output, and I didn't properly check my own code. Thanks for responding. So... that being said... maybe it actually would be nice to suppress the output for tests that pass? hmm...

On a related note: I want to use console.log because I am having a lot of trouble trying to get the Eclipse debugger to connect to node.js.

Am I the only one who finds this tricky? How do you guys debug node.js? With a debugger, or with console.log statements?

HHHmmm with 9 upvotes, on where it actually logs TO?!? might someone help? I'm using webstorm, and I'm not seeing it in the Process Console or the Debugger Console of the debug window.

That depends on the reporter, but usually the output is logged to stdout of the process that calls mocha.
