Today we are living in a quality driven information technology and wireless application world, and if someone says that it is quality that gives you an edge in business then it won’t be wrong. In past couple of years, the world has become techno-savvy and quality has turn out to be the major factor for successful software development. Now if try to relate quality in IT industry the most vital aspect that comes into the main picture is software testing. In simple words software testing can be defined as process aimed to evaluate various attributes of software and determine whether the software has been capable to meet the desired result.
Any organization that neglects this important process in software development life cycle and the quality control standards can destroy its own image and the brand value of the company. Furthermore, considering about the drastic outcome any negligence in software testing can result in the waste of the whole amount of money that you have spent on your project. Having a software test plan is a necessary feature of any software documentation. The reason of software testing can be quality assurance, confirmation or reliability estimation. These days’ software is widely used in many critical applications, and the outcome of a bug in any software can cause huge losses.
All software testing companies in India and across the globe conduct two major types of testing, i.e. Manual testing and Automated testing. Manual software testing generally entails manual interacting with application, and observing the outcomes very carefully. In addition to this a manual testing allows the tester to execute random testing in comparison to automated testing. It is important to understand that the more any tester spends time in playing with the feature, the better the odds of finding real user bugs.
However, automated testing is different from manual testing. Talking about some of the advantages of automated testing; it provides you with the facility to run automation against code that changes regularly to identify regressions in a sensible manner. Apart from this automated testing provides your facility to run automation in mainstream scenarios.
Nevertheless, when any of these methods are used by any software testing firm, they further divide it out in various types of testing standards like the White box testing and Black box testing, depending upon the given set of requirements. It is very essential point to understand that any software testing is performed in perspective with the competence and compatibility of software developed. Moreover, Black-Box and White-Box software testing can be defined as:
Black Box Testing: This testing procedure takes an exterior viewpoint of the object that need to be test to derive any test cases. In other words it is a testing that is performed without the knowledge of the internal working of the system. Black box testing is done in respect to the specifications, without any knowledge of the program. Also, known as functional testing, this testing have following advantages:
O It is unbiased because the designer and the tester are independent of each other.
O The quality control personnel do not need to know about any specific programming languages and the testing is performed from the point of view of the user.
White Box Testing: This is the next major technique of software testing. It is a test case design process that makes the best use of control structure of the procedural design to obtain any test cases. Also, known as structural and open box testing; it is different from black box testing and can be easily performed at different level starting from unit to system testing.
However, it is recommended to execute white box testing during the unit testing phase. It also makes use of programming code to examine outputs. Moreover, this method needs the detail knowledge and programming skills to recognize all paths through the software and can be further categorized as:
o Control Flow Testing
o Data Flow Testing
In last few years many types of software testing methods have been developed to meet up with the various business requirements. In order to offer the best software solution, today it has become very important to execute the finest quality standards, software testing procedures and professionals indulged software development process have to constantly focus on enhancement of their software products. Thus, the success of any software development directly depends upon software testing.
