Mocha Test Failing To Run On Nodejs Server

Objective Find out why my tests crash when I fail the assert. Background I have a very simple NodeJs application, and I am using Mocha for BDD with no assertion framework (just the

Solution 1:

TL;DR

This is somehow an expected behavior from npm run.

Explanation

After a long time of searching, I found a threat that lead me in the right way:

• npm error ELIFECYCLE while running the test

What happens here, is that mocha returns the number of failed tests. So if all tests pass, mocha returns 0 and npm continues without throwing an exception.

If however, X tests fail, mocha will return X. Because the returned result from running the script is different from 0, npm will throw an exception with code X and will fail execution.

Venting

Personally, this behavior is crap. I don't know who to blame here, if mocha for returning an arbitrary number when an arbitrary number of tests fail, is npm for refusing anything other than 0, or me, for apparently not knowing how to run tests, or at least keep up with the technologies to do so ....

Now I need to go on and find a decent way to run tests using mocha and npm. Hoping this helps someone.
