Is Your Software Bug-free?

Overview

Overview

The software that you use every single day is prone to bugs and errors, sometimes critical. Starting from the simple-interface card game you play for fun to the operating system your computer uses, everything contains errors that may or may not surface until a specific action is performed. Therefore, software testing is required for all software before it can be released in the market.

Testing methods

Testing involves a rigorous process of taking the software through a series of procedures; in the event of finding an error or a bug, tracing and debugging operations are conducted on the software to rectify the error. If the error cannot be rectified, codes are included to make the software handle the error without crashing or causing registry errors.

The most common methods of testing are the black box, white box and grey box testing. Black box testing involves the tester to treat the software as a black box and he assumes the role of a software user and tests the software by giving various inputs at every stage. White box testing gives the tester access to the internal structure of databases and algorithms, and this ensures completeness of the test. Grey box testing combines aspects of black and white box testing processes, because while the tester can gain access to the internal structure, he uses that information just to design test cases for the software test process. This mode of testing is particularly useful when integration testing is done for two different modules of a program coded by different programmers.

Different Levels of testing

A software program has to be tested at different levels because a bug in one module may cause significant developments in other modules. Therefore, testing each module separately (unit testing) is as important as combined testing of one module for its compatibility in code with another (integration testing). The software has to be tested as a whole bundle too (system testing), because this is the package that the customers are going to use. This is done on an external system (system integration testing), sometimes in the presence of the customer to ensure that all his requirements are fulfilled (acceptance testing).

Further, alpha and beta testing are also done by which the product is tested for bugs and errors by a small number of potential users or a team in the development company in alpha testing, while beta testing involves a considerably higher number of users.

Why should a product be tested?

Software, like any other commercial product, has to meet customer requirements and gain effective satisfaction of the customer. In other words, it should serve its purpose well and in an error-free manner. For instance, word processors should be capable of handling all types of characters, numbers and symbols with support for multiple languages. Therefore, care should be taken to incorporate support for the above-mentioned clauses.
