Recursively run all tests in test directory using mocha

gistfile1.js

// this will find all files ending with _test.js and run them with Mocha. Put this in your package.json


"scripts": {
  "test": "find ./tests -name '*_test.js' | xargs mocha -R spec"
},

By default mocha will find all .js files, this only reduce the list to _test.js files

It actually find the files that match the pattern in subfolders too. It works for me.

Thank you for this trick

Recursively running all test files in a directory with Mocha can be achieved with a packaged flag.

mocha --recursive

Thanks whroman

Thanks whroman, precisely what I was looking for.

A cross platform kitten died.

it works for me to wrap glob path into quotes

"scripts": {
    "test": "mocha \"test/**/*.spec.js\""
}

@lxjwlt thanks mate, it works perfectly

Does this work in windows? isnt find command for linux ?
I have test:unix : ""test:": "NODE_ENV=testing ./node_modules/mocha/bin/mocha $(find ./test -path '.tests') --reporter spec", -- which works for linux,

I have "test:win": "set NODE_ENV=testing&& node node_modules/mocha/bin/mocha **dont know what to replace it with here ** --reporter spec",

-- Answering my own concern
replacing $(find ./test -path '.tests') with mocha ./test --recursive -- works in Windows

@Byloor, Near as I can tell, your solution seems to work on both Windows and *NIX systems. This is the form I used:

"unit": "cross-env NODE_ENV=test LOG_LEVEL=silent nyc mocha ./test/unit -name '*_test.js' --recursive --compilers js:babel-core/register -R spec"

@lxjwlt, Gracias! This was the simple fix for me. Single quotes also allow you to avoid escaping.

  "scripts": {
    "test": "mocha --require test-setup.js './**/*.spec.js'"
  }

Single quotes are not working for me in Windows 10.

mocha './**/*.spec.js'

Warning: Could not find any test files matching pattern: './**/*.spec.js'

THanks so much for this @timoxley

@Heeseok The following worked for me

"scripts": {
    "test": "find ./**/tests -name '*spec.js' | xargs ./node_modules/.bin/mocha -R spec"
}

Also, to avoid using a pipe, you can use this version of find:

"scripts": {
  "test": "find src -name '*.spec.js' -exec mocha --require @babel/register {} \\;"
}

Where:

• src is the folder where to find your unit test scripts.
• *.spec.js is the regular expression that will match the files you want to use with mocha.
• @babel/register a register to use (for instance for TypeScript: --require ts-node/register).

In case anyone is interested, I actually switched to jest, because it seems to have a much easier test script.

"scripts": {
  "test": "jest"
}

That's it 😁
