npm error ELIFECYCLE while running the test

Question

I am using mocha-phantomjs setup for unit testing. I have following package.json scriot to run the tests.

\"scripts\": {
\"test\": \"npm run testFlickr\",
\"         


        

Answer 1

I was having this same problem, and what fixed it for me was when I run my unit tests, do NOT use

npm run test

instead use:

npm test

Answer 2

And when I run the command npm test in cmd, the test run alright

No they aren't. You have 6 failing tests. The exit code of mocha-phantomjs is equal to the number of failing tests. Run mocha-phantomjs ./test/FlickrTest.html directly and see what is failing. Realize the PhantomJS is a bit different than your browser - you may have to debug it.

Your script setup is odd. You should just have:

"scripts": {
   "test": "mocha-phantomjs ./test/FlickrTest.html"
}

Then the odd node errors should go away.

Answer 3

This is a problem when using npm run, it has to do with Mocha exiting with code !== 0 whenever a test fails. If you are on Windows try this:

"scripts": {
  "test": "npm run testFlickr || ECHO.",
  "testFlickr": "mocha-phantomjs ./test/FlickrTest.html || ECHO." 
}

Answer 4

When running npm test it squelches ELIFECYCLE errors so you never encounter this experience.

Reference to code

Once you move a test script to a different script-name you'll start seeing ELIFECYCLE errors.

My fix is to add a exit 0 to the end of the command. For your code it would look like this:

"scripts": {
  "test": "npm run testFlickr",
  "testFlickr": "mocha-phantomjs ./test/FlickrTest.html; exit 0" 
}
