In order to write an effective unit test, you want to be able to isolate a unit of code and test only that unit – nothing else. It is fairly common and good practice to consider a module such a unit, and this is where Jest excels. Jest makes isolating a module from its dependencies extremely easy by automatically generating mocks for each of the module's depenedencies and providing those mocks (rather than the real dependency modules) by default.

Testing can be hard and Ember doesn't exactly have the greatest resources for testing. QUnit is the "official" testing framework for Ember.js apps and it has the most resources dedicated to it which can make using something like Jasmine a bit harder.

Ember requires a bit of setup to get working properly with Jasmine. Before anything else, we need to set up our helpers/spec_helper.js file. The following code sets Ember up for testing, gives us our test helpers, and even puts a small div showcasing our app in the bottom right corner...

Developers almost universally agree that unit tests are a VERY GOOD THING when working on a project. They help you feel like your code is airtight, ensure reliability in production, and let you refactor with confidence when there is a need to do so.

AngularJS code touts its high degree of testability, which is a reasonable claim. In much of the documentation end to end tests are provided with the examples. Like so many things with Angular, however, I was finding that although unit testing was simple, it was not easy. Examples were sparse and though the official documentation provided some snippets of examples, putting it all together in my “real-world” case was proving challenging. So here I’ve written a little bit about how I ended up getting that wonderful green light for a passing build to show up.

Frisby is a REST API testing framework built on node.js and Jasmine that makes testing API endpoints easy, fast, and fun. 

Inspector helpers are useful for viewing details about the HTTP response when the test does not pass, or has trouble for some reason. They are also useful for debugging the API itself as a more user-friendly alternative to curl.

The robustness engrained into key parts of the web stack gets forgotten as we build more dynamic applications, users might not get anything when even a small problem occurs. React provides a straightforward means to creating adaptive-hybrid or isomorphic web applications which can inject robustness back into our projects.

Jest is a new javascript testing tool announced today. I thought I'd take it out for a spin testing the UI of a simple vanilla JS app - no CommonJS modules, no fancy stuff. Just old school JavaScript. Granted, it's probably not what the tool was optimized to do, but it totally worked.

The thing about Jest is that it mocks everything. Which is priceless for unit testing. But it also means you need to declare when you don't want something mocked. 

Unit testing is a technique that helps developers validate isolated pieces of code. End to end testing (E2E) comes into play when you want to ascertain that a set of components, when integrated together, work as expected. AngularJS, being a modern JavaScript MVC framework, offers full support for unit tests and E2E tests. Writing tests while developing Angular apps can save you great deal of time which you would have otherwise wasted fixing unexpected bugs. This tutorial will explain how to incorporate unit tests and E2E tests in an Angular application. The tutorial assumes that you are familiar with AngularJS development. You should also be comfortable with different components that make up an Angular application.

We will use Jasmine as the testing framework and Karma as the test runner. You can use Yeoman to easily scaffold a project for you, or just quickly grab the angular seed app from GitHub.

This article is a Step by Step guide on how to do Unit testing of ExtJS application using Jasmine Framework. The MVC approach of ExtJS along with the ‘Behavior Driven Testing’ approach of Jasmine Framework enables independent testing of ExtJS model, store and controller.
