Object oriented software testing methodologies processes

As software development is a long term process,so most of the software development companies today actually work on the basis of the software development methodologies. Testing takes place to complete the oot cycle mention below testing are required. Objectoriented analysis and design ooad is a technical approach for analyzing and designing an application, system, or business by applying object oriented programming, as well as using visual modeling throughout the software development process to guide stakeholder communication and product quality. It is seen whether the class attributes are implemented as per design and whether the methods. The craft of software testing object oriented software testing. In object oriented systems, testing encompasses three levels, namely, unit testing, subsystem testing, and system testing. The points that should be noted while developing test cases in an object oriented environment are listed below. Pdf comparison between traditional approach and object. Objectoriented testing is a collection of testing techniques to verify and validate object oriented software. Object oriented software engineering oose is an object modeling language and methodology. In the objectoriented approach, the focus is on capturing the structure and behavior of information systems into small modules that combines both data and process.

Object oriented analysis ooa and objectoriented design ood are processes uml has rules for syntax and usage but it does not have procedures i. The fulllifecycle objectoriented testing floot methodology is a collection of testing techniques to verify and validate objectoriented software. Whenever large scale systems are designed, object oriented testing is done rather than the conventional testing strategies as the concepts of object oriented programming is way different from that of conventional ones. The main aim of object oriented design ood is to improve the quality and productivity of system analysis and design by making it more. The approach of using object oriented techniques for designing a system is referred to as object. The methods used to design test cases in oo testing are based on the conventional methods. The whole object oriented testing revolves around the fundamental entity known as. A hierarchical approach software testing is a resourceintensive activity. In unit testing, the individual classes are tested. The full life cycle objectoriented testing floot method.

Information covered in the document includes a brief overview of the oom, its benefits, the processes and some of the major techniques in oom. However, these test cases should encompass special features so that they can be used in the object oriented environment. Requirement testing analysis and design testing code testing integration tests system tests user testing its used to discuss test plans and execution. Object oriented methodology oom is a system development approach encouraging and facilitating reuse of software components. With this methodology, a computer system can be developed on a component basis which enables the effective reuse of existing components and facilitates the sharing of its components by other systems. Testing is a continuous activity during software development.
