This question already has answers here : Mocha / Chai expect.to.throw not catching thrown errors (6 answers) I've been trying to do a text of a function that handles errors in a way that, if it is a valid error, it is thrown, but if it is not, then nothing is thrown. The problem is that i cant seem to set the parameter while using: expect(handleError).to.throw(Error); The ideal would be to use: expect(handleError(validError)).to.throw(Error); Is there any way to achieve this functionality? code of the function: function handleError (err) { if (err !== true) { switch (err) { case xxx: ... }

This question already has answers here : Mocha / Chai expect.to.throw not catching thrown errors (6 answers) I'm hoping to find some help with this problem. I'm trying to write tests for an application I am writing. I have distilled the problem in to the following sample code. I want to test that an error was thrown. I'm using Testacular as a test runner with mocha as the framework and chai as the assertion library. The tests run, but the test fails because an error was thrown!

I have a setting in my angular based website that turns a dropdown on and off. If it is off, then it does not show on the main page. With Protractor, I need to check to see if this element is not present when the switch is off. However, I should not be thrown into Element Not Found Error, as it is one test in a set of many. How should I do this? I have tried to do: expect($$('.switch').count()).to.equal(0).and.notify(next); But I am getting an AssertionError with this... Another option that worked a bit better for me, and uses protractor 'way' of doing things http://angular.github.io

Lets say I want to write this simple task. But I want to write a test validating that: This task emits object. Object has a property name. I'm testing with mocha and chai expect. Thanks in advance. I've tried every possible variant that came to mind, but could not come up with a solution. var util = require('util'), EventEmitter = require('events').EventEmitter; function SomeTask() { var self = this; setInterval(function() { self.emit('data', { name: 'name' }); }, 5000); } util.inherits(SomeTask, EventEmitter); module.exports = SomeTask; Here's an example using spies. https://github.com
