A guide to software testing and the correct way to carry out a unit testing project b

The principles of unit testing, such as, dropping development expenses, making available superior quality products and cutting the growth time, are quite renowned. Below a guide to software testing with regards to what <a href=”http://site.typemock.com/general-unit-testing-page/2009/9/14/software-testing-guide-how-to-start-unit-testing-net-project.html”>software testing tool</a> you require and how to perform .NET unit testing projects has been briefly explained.
The tools that you need for unit testing are framework and mocking framework.

Framework – The primary tool that you require is a <a href=“http://site.typemock.com/“>unit testing</a> framework. Here you possess a few choices. In case you are working with Microsoft Visual Studio 2008 Professional, then you will enjoy the Microsoft framework already being installed within your system. The unit testing framework is also available along with Microsoft Visual Studio 2005 Team System.

You can also choose from other unit testing frameworks, such as, MbUnit, which is currently a division of Gallio venture, xUnit or NUnit. There are negligible disparities between the various frameworks, however the key characteristics continues to be the same. Nevertheless, the Microsoft unit testing framework is also available along with an incorporated test runner. It permits you to carry on tests within Visual studio. To accomplish similar user-friendliness with the other frameworks, such as, MbUnit, xUnit or NUnit you will require Jamie Cansdale’s TestDrive.Net.Find more details at <a href=”http://site.typemock.com/general-unit-testing-page/2009/9/11/test-driven-development-tdd.html”>test driven development</a>

For bringing into play the API and characteristics of the various frameworks, you simply require to include references within your unit test project. The Microsoft unit testing framework include a unique Test Project, while the other unit test framework employs a standard DLL for performing the tests.

Mocking Framework – The second software tool that you require is a unit testing mocking framework, such as, Isolator. Then you need to stick to the guidelines mentioned below to carry out the initial test. You must include references with Isolator framework DLLs.

While performing your test, design a test class and give it a name. While assigning a name you have to follow a particular pattern, for example, in case you name your class as MyClass, then you can name your test class as MyClassTests.

When creating the primary unit test you need to make up your mind which public procedure you would like to test, the special scenario along with the projected outcome for that particular scenario. Make use of that information when titling your test.

Now attach the test content. A test normally includes three segments, for instance, arrange, act and assert. Arrange means the test setup, while act is the real invocation and assert is the authentication of success or failure of the test.

izh_test is a xUnit-like framework. Its advantages over existing alternatives are that it

1. uses file compare for checking results of test.

2. doesn’t depend on partial program language using external xml test descriptions.

The package is distributed by license GPL with source code “as is”.Authors develop the system depending on own current needs. So they implement only things that they use, nothing else.

If someone needs something new he should implement it himself. izh_test isn’t commercial project and any new useful extern changes and additions will be included by the same license GPL . As example we need more correct english documentation. The list of task to implement is in the part “Roadmap” Source codes of izh_test depend onlibrary izh_base . This library is distributed by the same license GPL ,but it won’t be included extern changes and additions by license GPL .

Lightweight Test Automation Framework is an integration testing tool, which works by scripting the web browser to perform a sequence of actions against your application’s UI – entering text and clicking links and buttons exactly as a real user would – and then checking that the expected results can be seen in the browser window.

Just in case you don’t know the difference between unit testing and integration testing:

Unit tests work against the API of a particular component in your code.  Ideally, they test only that single isolated unit (hence the name), which allows them to pinpoint any problems exactly where they occur.  Unit testing tools for .NET include NUnit, mbUnit, and xUnit.

Integrations tests combine multiple components.  Typically, they work at the UI level to test that your JavaScript, your HTML, your controller code, your model code, and your database all work together.  Integration testing tools for .NET include Selenium, Watin, and Lightweight Test Automation Framework.
