How do you install and run Mocha, the Node.js testing module? Getting “mocha: command not found” after install

Question

I\'m having trouble getting Mocha to work as expected, and I\'d love to say as documented, but there (appears) to not be much documentation on actually getting the thing run

Answer 1

To run Mocha with mocha command from your terminal you need to install mocha globally on this machine:

npm install --global mocha

Then cd to your projectFolder/test and run mocha yourTestFileName.js

If you want to make mocha available inside your package.json as a development dependency:

npm install --save-dev mocha

Then add mocha to your scripts inside package.json.

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

Then run npm test inside your terminal.
