How to make Istanbul generate coverage for all of my source code?

node.js mocha sinon chai istanbul

Currently Istanbul is only generating coverage for files that are used in my tests, which is okay, but seems to defeat the purpose of having coverage somewhat.

I have no Istanbul configuration, and am invoking it via npm test with the following script string:

$ istanbul cover _mocha -- -R dot --check-leaks --recursive test/

Is there a way to generate coverage for all of my source code?

Found the answer, I think I'm partly lucky that the directory structure I have chosen allows me to use this option, but my test command is now:

$ istanbul --include-all-sources cover _mocha -- -R dot --recursive test/

The --include-all-sources is the important part.
