Confusion when mocha installed globally

[j-hannes]

Hi,

first of all thanks for that nice little tool.

After spending quite some time trying to figure out why mocha-clean had no effect on my stack trace I had a deeper look into it and found that the reason was I installed mocha globally via npm install -g mocha, but mocha-clean monkey-patches mocha's Runner.prototype.fail function of the locally installed mocha package.

So in order to shorten the stack traces I need to run node_modules/mocha/bin/mocha? Or did I miss anything here?

Cheers,
Hannes

yes, you need to run ./node_modules/.bin/mocha.

the best way to do this is to add this to your package.json, and run npm test:

"scripts": {
  "test": "mocha"
}

you're right that this indeed needs to be documented somewhere.

Awesome. Ah I see, npm uses the local instance too. Good to know.

Yeah maybe add in the readme.md to npm install mocha too. It is written in the wiki for the build tools I believe, but not in the readme.

Thanks.

We tried this as well. This package has to be installed in the same level as your suite.

For example

root\
root\package.json  <---- mocha installed at this level
uitest\
uitest\test\
uitest\test\mocha.opts <---- --require mocha-clean here
uitest\package.json <---- mocha-clean has to be installed at this level
apitest\
apitest\test\
apitest\test\mocha.opts <---- --require mocha-clean here
apitest\package.json <---- mocha-clean has to be installed at this level
