The increased complexity of browser-executed code has increased the need to write unit test cases for JavaScript code. This article describes some of the most common tools for unit testing JavaScript: QUnit, YUI Test and JSTestDriver. The learning curve can be steep if you do not typically write tests for client-side scripting and testing the user interface could require adjustments in your thought process. This article provides code examples that will walk you through sample test cases.

In this blog post, Rob Stevenson-Leggett gives a detail presentation on how to start some simple Javascript unit tests using QUnit as the test framework and Sinon.js as a mocking framework. QUnit is a JavaScript test suite used by the jQuery project to test its code and plugins but is capable of testing any generic JavaScript code and even capable of testing JavaScript code on the server-side. Sinon.JS is a standalone test spies, stubs and mocks for JavaScript. It has no dependencies and works with any unit testing framework.

Unit testing JavaScript applications can seem difficult. Issues arise with JavaScript scope, asynchronous XHR requests, DOM manipulation, and all the different browsers and platforms. Sometimes, JavaScript unit testing seems unreliable, brittle, or take more time and effort than it’s worth. The good news is that dozens of JavaScript test frameworks, libraries, and test runners help solve the problems. These make implementing unit tests for your JavaScript applications quick, reliable, and easy to maintain.

This blog post presents the changes to unit testing made in the new version of Visual Studio. The Test View and Test Results windows have been replaced by the Unit Test Explorer, a new user interface that let developers quickly interact with their tests. Third party test frameworks are supported by a new test meta-runner that coordinates and controls the flow of data between the user interface and the underlying test frameworks. Visual Studio will also provide a true native unit testing framework for C/C++. A new test isolation and …

This video provides an overview of the methodology used to easily unit test your Asp.Net (aspx) pages with the open source dll ApprovalTests.

Running your SQL Server database unit tests within the scope of a single transaction allows you to roll back any changes that the test enacted after the test ends. This article propose a step by step approach to achieve this goal. You start to create a transaction in your Transact-SQL test script that uses BEGIN TRANSACTION and ROLLBACK TRANSACTION. Then you will create a transaction for a single test method in a test class and then a transaction for all test methods in a given test class.

Mockito is an open source mock framework for Java that letsyou write beautiful tests with clean and simple API. This video shows how to verify mock objects using Mockito.

Unit tests are comprised of test methods and classes that verify whether a particular piece of code is working properly. This article introduces test methods in the salesforce.com environment. It details why test methods are a critical part of Force.com application development, test method syntax, best practices, and advanced topics such as test methods for Visualforce controllers and Apex web service callouts.

This blog post explains how to separate integration and unit tests with Maven, Sonar, Failsafe and JaCoCo. This is achieved by executing unit tests via Surefire and integration tests via Failsafe. Then you  show as much information about them as possible in Sonar. The post provides detailed command lines and Maven configuration files to achieve this goal.
