It can be upgraded from small to large systems at a greater ease than in systems following structured analysis. As it follows a top-down approach in contrast to bottom-up approach of object-oriented analysis, it can be more easily comprehended than OOA. In traditional structured analysis models, one phase should be completed before the next phase. This poses a problem in design, particularly if errors crop up or requirements change.
It is based upon functionality. The overall purpose is identified and then functional decomposition is done for developing the software. The emphasis not only gives a better understanding of the system but also generates more complete systems. The initial cost of constructing the system is high, since the whole system needs to be designed at once leaving very little option to add functionality later. The specifications in it are written in simple English language, and hence can be more easily analyzed by non-technical personnel.

Object oriented testing methods. An efficient software testing strategy includes two types of tests, namely, low-level tests and high-level tests. Low-level tests ensure correct implementation of small part of the source code and high-level tests ensure that major software functions are validated according to user requirements.
A testing strategy sets certain milestones for the software such as final date for completion of testing and the date of delivering the software.
These milestones are important when there is limited time to meet the deadline. In spite of these advantages, there are certain issues that need to be addressed for successful implementation of software testing strategy.
These issues are discussed here. Dinesh Thakur is a Freelance Writer who helps different clients from all over the globe.

System Testing is a type of software testing that is performed on a complete integrated system to evaluate the compliance of the system with the corresponding requirements. In system testing, integration testing passed components are taken as input. The goal of integration testing is to detect any irregularity between the units that are integrated together.
System testing detects defects within both the integrated units and the whole system. The result of system testing is the observed behavior of a component or a system when it is tested. System Testing is carried out on the whole system in the context of either system requirement specifications or functional requirement specifications or in the context of both.
System testing tests the design and behavior of the system and also the expectations of the customer. It is performed to test the system beyond the bounds mentioned in the software requirements specification SRS.
