Declaring output file in mocha.opts configuration

Im trying to get Mocha reporter to output a html file, using the mocha.opts configuration file:

--compilers coffee:coffee-script/register
--reporter html-cov > tests.html

However this always returns the following:

→ mocha

/usr/local/lib/node_modules/mocha/bin/_mocha:432
  if (!files.length) throw new Error("cannot resolve path (or pattern) '"
                           ^
Error: cannot resolve path (or pattern) '>'

If I pass the command mocha --reporter html-cov > testes.html directly in the shell it does work.

What am I missing?

You can't put the redirection in mocha.opts. When you do it on the command line, the whole command is interpreted by the shell and > is understood to be a redirection. However the mocha.opts file is meant to be read as options and only options, nothing else. Mocha is not able to figure out that > tests.html is meant to be a redirection. You can put this in your mocha.opts:

--compilers coffee:coffee-script/register
--reporter html-cov

and keep > tests.html on the command line or use a wrapper script if you want to avoid typing it.

If there were an option to tell Mocha to output into a specific file (for instance, --output file) then you could put that in mocha.opts but Mocha has no such option right now.
