How to run mocha and mocha-phantomjs tests from one “npm test” command in node.js?

Question

I have got few node packages which works in node.js environment and also in browser. Now I have got two seperate tests (for each environment). What is the best way to run th

Answer 1

I like the following:

  "scripts": {
    "test": "npm run test-node && npm run test-browser",
    "test-node": "mocha -R spec ./test/node/index.js",
    "test-browser": "mocha-phantomjs ./test/browser/index.html"}

The && only runs the second if the first passes, and you can run either separately if you want. Note that npm always uses the relative mocha (inside node_modules), not the global one, so there's no harm in just calling mocha and mocha-phantomjs directly. You can be even more efficient with mocha's -b option for bail, which will quit as soon as it encounters an error.

Came here looking for information on configuring npm with karma. @dankohn's answer can be adapted thusly:

"scripts": {
  "test": "npm run test-node && npm run test-browser",
  "test-node": "karma run",
  "test-browser": "karma start --single-run"
}

Hope this helps someone else out.

You can also use npm-run-all package:

npm install npm-run-all --save-dev

"scripts": {
  "test": "npm-run-all test-mocha test-mocha-phantomjs",
  "test-mocha": "mocha ./test/node/index.js --reporter spec",
  "test-mocha-phantomjs": "mocha-phantomjs ./test/browser/index.html"
}

It will run local copies of mocha and mocha-phantomjs. Twitter bootstrap uses this library for development.
