Use Cases is the best technique to figure out the technical aspects of the system, it help you understand the functionality of the system and its interaction with the humans (Actors), the Use Case Diagram is best to present your requirements in terms of processes and it allows you sort out any errors before the implementation of ...

There are many solutions to these problems, but none of them are easily implemented. Each area of testing should be heavily modified. In math, for example, there is a str...
Abstract— Software testing is very important element in various product accuracy. Software testing is set of activities conducted with the intent of finding errors in software. It also verifies and validate whether the program is working correctly with no bugs no not. There are basically three levels of testing- Unit, Integration and System. Unit testing referred to as testing in small whereas Integration and System testing are referred to as testing in large. Various testing techniques available for designing of test cases. This paper basically deals with various techniques available to design software testing test cases.
Testing is one of the important methods to boost the confidence of the developers in the reliability of software. Sometimes, programs that are not properly tested perform correct for few months and even years too before some input sets shows the presence of critical errors. Incorrect application that is released to public without fully tested could result in client dissatisfaction and moreover it is important for software in applications that it is free of software faults which might lead to heavy economic loss or even endanger lives. In the past durations, systematic ways to software testing procedures and tools have been developed to avoid many problems. Testing is the most usual technique for fault detection in today’s organization. Main aim of application testing is to boost one's confidence in the correctness of the program being tested.

Few systems for example: an embedded system is safety critical when installed in a vehicle. Such systems are extremely expensive to change; others must change frequently in response to varying requirements (e.g. business systems). Systems which are very expensive to change need extensive in advance analysis to ensure
A documentation framework is essential for any large project; hence, RUP describes how to document functionality, constraints, design decisions and business requirements. Use Cases and Scenarios, are examples of artifacts prescribed by the process and have been found to be very effective at both capturing functional requirements and providing coherent threads throughout the development and deployment of the system.
The UMLS is a very detailed subject, and I have provided a brief overview. To adequately understand the complexity of the UMLS would require many pages of detailed explanations. Mainly, for our purposes we simply need to understand a broad overview to relate the importance of the UMLS to the HIM
UML (Unified Modeling Language) is a universal modeling language in the field of software engineering. It is designed to provide a standard way to visualize the design of a system allowing the programmer to visually see what is required for the software he/she is working on. Many people believe that UML is not important to learn. That it is simply just a time consuming task, and in some cases that is true. But while UML can be time consuming, it can help multiple people understand the essence of a program that is being created. It allows everyone to be on the same page of what the end goal is and of the means to reach the end.
There are different types of UML diagrams. Each UML diagram is designed to let developers and customers view a software system from a different perspective and in varying degrees of abstraction. UML diagrams commonly created in visual modeling tools include: use case diagram which displays the relationship among actors and use cases. Class case diagram models class structure and contents using design elements such as classes, packages and objects. It also displays relationships such as containment, inheritance, associations and others. Sequence diagram displays the time sequence of the objects participation in the interaction. This consists of the vertical dimension (time) and horizontal dimension (different objects). Collaboration diagram displays an interaction organized around the objects and their links to one another. Numbers are used to show the sequence of messages. State diagram displays the sequences of states that an object of an interaction goes through during its life response to received stimuli, together with its response and actions. Activity diagram displays a special state diagram where most of the states are action states and most of the transitions are triggered by completion of the actions in the source states. This diagram focuses on flows driven by internal processing.

While developing a software many complex activities are required which in turn have dependencies along them. Large software projects require the involvement of programmers, documentation specialists, program managers, architects, database analysts, system analysts, , and trainers and last but not the least testers. Along with their independent responsibilities these persons are also responsible to maintain and keep a check on the software system quality as well.
Requirements engineering begins during the communication activity, continues into the modeling activity, and builds a bridge from the system requirements into software design and construction. Through requirements engineering, there is an examination of the context of software work performed. It is essential for the software engineering team to understand all requirements of a problem before the team tries to solve the problem. An identification of specific needs that the design and construction must address is also included. Further is a need for the identification of the priorities that guides the order for the completion of work. This i...
