The Object Oriented ( Oo ) Environment And The Strategies That Are Used For Testing

“During the object-oriented analysis (OOA) phase object-modeling techniques are used to analyze the functional requirements for a system and create models which reflect the logical design of the system. During the object-oriented design (OOD) phase of the system, models are elaborated upon to include implementation specific details that show how the physical design of the system will come together. OOA focuses on what the system does (its static structure and behavior), OOD on how the system does it (its run-time implementation).”

In Object-orientated approach methodology, a system is viewed as an object (Govardhan & Munassa: 71). This approach intergrades data and processes into objects. It emphasizes the construction and testing of object models. This technique uses UML diagrams such as Communication Diagrams, which show the relationship between objects, Development Diagrams which show how a complete system will be deployed on one or more machines, the Class Diagram and Sequence Diagram.

As computers and software are used in critical applications, the outcome of a bug can be severe. Bugs can cause huge losses. Bugs in critical systems have caused airplane crashes, allowed space shuttle missions to go awry, halted trading on the stock market, and worse. Bugs can kill. Bugs can

One of the most important factors when developing software is the early detection of faulty software for reducing development cost and assuring software quality. If the faultiness is not detected in the early stages and if detected and not fixed, than it will carry on throughout the project and the cost for fixing it after the delivery would be more than 50% or could be 100%

Software testing refers to the process of finding an error of ensuring that particular software meets its specification. The growing complexity of software division into various application demands highly skilled engineers with the appropriate mix of expertise. Testers need to do sampling such as generates a set of test cases to validate against the user

It is the major quality control which is used during software development life cycle. The basic function of software testing is to identify errors in the software. During the requirement analysis and the software design phase, the output of a document is usually textual and non-executable. Once the design phase completed successfully then coding phase start, the computer programs are available that can be achieved for testing purposes. It is implies that testing means not only to uncover errors introduced during coding, but also the errors introduced during the previous phases. Thus, the main goal of software testing is to find requirement, design, and coding errors in the programs. To perform testing consequently, different levels of testing

Linguistic is the analysis which is applied to the object oriented which gives the accurate results when compare to other analysis. The main drawback of the object oriented approaches for software development is the object oriented analysis process which do not having the exact information. When the particular project was given by the clients they specify the information about the project which was in natural language. The information is tendered in linguistic it is a study of scientific language. The software engineering projects starts from the information given by the customer. Then the company has to work with that and analyze the complete information, requirements about the project. The main thing is to know about the project is to

Object-oriented design is a method and style for software system development that amounts to encapsulating data and operations in abstractions. This method produces some abstractions that are usually implemented in an object-oriented programming language, which supports the object oriented style through its syntax and semantics. It does so by providing an object model and by offering built-in methods for object construction, method calls, field access and deletion of objects. Classifying abstractions and taking them apart into their subcomponents is not a built-in construct of object-oriented programming languages.

Over the past few decades, online industry has developed in leaps and bounds. Nowadays, testing is playing an instrumental role in all software development processes. A good testing program can help to prevent software defects, reduce the number of bugs, errors, and improve the overall software quality. Besides, when it comes to testing online, it has been withdrawing more and more attention from any individuals or organizations who construct and operate websites, such as e-commerce websites, information, customer service websites, blog and so on. They deeply understand that an optimized website can lead their businesses to a higher position in the competitive world. On the other hand, a bad website experience might bring significant

OOP, an abbreviation for object-oriented programming is simply code that “attempts to place a new layer of abstraction between the programmer and the data he is working with … this layer will help the programmer develop better code more quickly than he could do before.” (McHale). OOP languages must include four

Software Engineering is systematic approach to development, operation, maintenance and retirement of any software. Development of any software follows a series of steps known as the ‘Software Development Cycle’ (SDLC). Software testing is an important part of SDLC. Software testing is the major quality control measure employed during the software development. Its basic objective is to detect errors in the

Software testing is a technical task, but it also involves some important considerations of economics and human psychology. In technical aspects it is the process of analyzing a software item to detect the differences between existing and required conditions (that is defects/errors/bugs) and to evaluate the features of the software item”. A software error occurs when the program does not do, what its end user reasonably expects it to do.

There are so many features of Object – Oriented Programing. Among all of them main features are ,

  Object-oriented analysis is concerned with developing an object-oriented model of the application domain. The identified objects reflect entities and operations that are associated with the problem to be solved.
