Typemock, the leading provider and pioneer of easy unit testing solutions, announced today their prediction that a rise in unit testing will occur in 2012 as software development continues to climb significantly. Eli Lopian, founder and CEO of Typemock , speaking at a developer seminar said, “In 2012, we will see a major shift in the efforts of software developers to focus on better code. Unit testing is significantly more important today as we see an eruption in software development in the coming years.” In addition, Lopian added “Unit testing is a key aspect of all Agile methodologies, and, in order to remain agile, unit testing must be properly executed.”

In an article on the Testing Tools Landscape, a leading analyst firm noted, “Now it is time for quality management and testing to respond to this faster-moving environment. Functional testing tools are not enough. Quality must move beyond the purview of just the testing organization and must become an integrated part of the entire software development life cycle (SDLC) to reduce schedule-killing rework, improve user satisfaction, and reduce the risks of untested non-functional requirements such as security and performance.” In addition, a recent Forrester report recommended that developers engage in automated testing, including unit testing, in order to build higher quality software.

According to one notable developer, there will also be more consideration for unit testing in software development. Kevlin Henney, co-author of several software architecture and programming practice books and former columnist for Better Software Magazine, was interviewed by Typemock on his predictions for the upcoming year, commenting that there will be “increased acceptance of unit testing and techniques surrounding it, particularly in domains where it has been considered off the menu.”

Corey Haines, self-proclaimed Software Journeyman and co-founder of Code Retreat had this to say: “Honestly, I see more of the same. Lots of people exposed to it for the first time. Lots of people trying it, finding it hard, then saying it doesn’t work. Lots of people trying it, finding it hard, keeping with it, and seeing benefits over the years.”

“Unit testing is like staying healthy,” said Lopian. “Staying healthy requires best practices such as eating right and working out. Similarly, development teams need the right practices in order to innovate faster. Just as it’s hard to start working out, many find it’s hard to unit test and thus stop – despite its well-known benefits. This is why Typemock’s vision has always been providing easy unit testing tools for agile software developers to release better software, even with legacy code.”

Testilence is an open-source unit testing library for PHP 5. It is published under the MIT license which means you are free and welcome to use it in any way. Like other JUnit inspired unit testing libraries, Testilence roughly follows the canon . It is however written with emphasis on what’s useful, not what’s usual, and combines original ideas with the best features found in different unit-testing toolkits into a coherent set.

Testilence differs from the above-mentioned canon in that you only get to have one assertion per test method (this is a Good Thing):

1. Multi-assertion test methods reduce test coverage, since the first failed assertion will abort the test method, skipping latter assertions in that method.

2. Single-assertion test methods provide the author with a strong incentive to think about the PUT, because each test method should name a behavior. Thinking of meaningful names for all the tests is sometimes painful, but the reward is a better understanding of the code.

3. Single-assertion test methods provide clearer picture to the reader.

Typemock,  the leading provider and pioneer of unit testing solutions announced today the official launch of Isolator ++.

Isolator ++ is the first isolation framework that allows developers to conduct easy unit testing for C++. As opposed to other unit testing solutions that require many sections of code to be modified in order to test it, Isolator ++ allows the user to mock any part of the code without any alterations. It also enables organizations to ensure that their final product meets industry standards.

The launch of Isolator ++ demonstrates Typemock’s ability to now offer solutions for easy unit testing for windows C++ developers in addition to .Net.

Isolator++ enables testing of any C/ C++ code (including complex code such as statics, globals and non virtual method) by allowing the user to intercept and fake their behaviours. The user can write tests with minimal lines of code, a major improvement on other frameworks which require multiple lines to make effective readable tests. The API is specifically designed to make tests more concise, more resistant to production code changes and easier to understand for new users. Isolator ++ works with all testing frameworks including Google Test and UnitTest++.

“Adding C++ solutions to our product range is a natural step for Typemock” commented Eli Lopian Typemock‘s founder and CEO. “With a growing number of developers writing in C++, especially with the increased popularity and demand for smart phones and other advanced technologies, there is an obvious need for an easy solution for C++ unit testing which ensures that the final product surpasses all regulatory requirements. This is imperative for the military, avionics, automotive and medical device industries where an error in the code can be critical.”

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.
