Testing javascript with Mocha - how can I use console.log to debug a test?
javascript, mocha.js, node.js
Solution
What Mocha options are you using?
Maybe it is something to do with reporter (-R) or ui (-ui) being used?
console.log(msg);
works fine during my test runs, though sometimes mixed in a little goofy. Presumably due to the async nature of the test run.
Here are the options (mocha.opts) I'm using:
--require should
-R spec
--ui bdd
Hmm..just tested without any mocha.opts and `console.log` still works.
Problem
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?
