The Benefits Of IBM I Series Unit Testing As Efficient

By Daniel Stone


There is no such thing as a perfect code. When it comes to software programming bugs are bound to be plenty during the development stage. Leave the clean up to quality assurance before alpha and beta release. With no proper work flow and organization during development stage, the process of development is going to take longer.

Linux and Microsoft 2000 are some of the Operating systems that work with the IBM AS/400. Also known as the I series, this system can compile programming languages such as C, assembly, C++, Perl and so on. This makes IBM I series unit testing an efficient method the test IBM applications.

This is a testing method where code is made to check the proper functionality of all fragments in the system, one by one. In a way, it is a process of automating tests in a compartmentalized way against the software. The tests are also added to version control as a means of documentation.

With this type of test the bugs in the code are discovered even before the function is added into the repository and on to the clients and testers. As a type of TDD or Test Driven Development, developers constantly check for the bugs during the process of making the whole system. Even with the isolation of one fragment from another during the tests, the overall continuous database integrity is not compromised.

This prevents the faulty products to reach testers and clients since the programming team is alerted of them automatically. This makes the whole process to be less costly than passing something that might still have fatal bugs to consumers. And with checking only parts it make changing these fragments work without affecting the original behavior of the existing code as a whole.

The program is protected from time and space bound factors. When the tests are done, the code is guaranteed to work under all circumstances even after updates done later. Like mentioned earlier, the whole system is protected from the domino effect of bugs and errors when an edit is done or when a feature is added. This makes sure that while the testing is compartmentalized, its connection to other modules remain.

In software development, the more code is added to the repository, the more difficult it is to find the faulty piece of programming if something crashes. This is not the case with unit testing. This results to other developers being reluctant to add in the program already written in fear that if they added to the repository it might destroy everything.

Deployment of changes and fixes also become faster. Since the goal of this method is to automate testing during the development and serves precaution for future edits and additions wanted by the client, it is designed for flexibility. There are no side effects to worry about.

There will always be a counter argument to disqualify this method. The strongest one being that this type of TDD is just too time consuming. But the point of this method is for future development and in circumstances that other modules might be added. The nature of unit testing also makes it readable for developers who might get deployed to the project in later stages.
