Along with, for implementing the new system, the ability of the organization is also checked. Coupling: Coupling is a measure of interconnection among modules in a software structure. Hence it is more secure and reliable than previously used on-line test simulators. Net project on E-Examination project is developed in different modules among them admin module is provided for professors who will prepare test paper for examination which is maintained securely. Test cases are chosen to exercise each portion. There are two Strategies for testing software that we use for testing our system: Code testing and Specification Testing. Thank you very much and Happy Productive Programming Everyone.
The database will retain user information IdNo, name, email address, etc. Content coupling: The highest degree of coupling, content coupling occurs when one module makes use of data or control information maintained within the boundary of another module. Back-to-back testing: — Comparison of test results from different versions of the system e. On this site you will get source code with the running project. Appear for the exam Student. Use case description Add Department Use case name Primary Actor s Description Precondition Post condition 1. Object design model Performance criteria Response time.
The left end marks the beginning of the tasks; the right ends its finish. The main objective of on-line test simulator is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. These checkpoints indicate that the management decision to be made after a phase is complete. There is no tool or procedure that assures correctness. However, bottom-up testing of critical low-level components is almost always necessary.
Operational Feasibility criteria measure the urgency of the problem or the acceptability of a solution. An individual could not have more than one user account. Feasibility study This activity involves the analysis of the problem and collection of the relevant information relating to the product. It is also needed less manpower to execute the examination. I believe in client satisfaction. Semantic error These errors occur in code that is correct according to rules of the compiler, but that causes unexpected problems such as crashes or hanging on execution.
Everything related to their progress in the system is marked manually. Student Registration Use Case Use case name Primary Actor s Description Precondition Post condition 1. Reliability: The system has to perform the online exam operations with no errors. Abstract : Online Examination System forms the lifeline of the Educational Institutes to the functioning of the Examination. Earlier tasks appear in the upper left and later ones in the lower right. System:-is the system which checks users or administrators inputs. In Code testing, we developed those cases to execute every instructions and path in the program.
Student examination module students ought to register with application and choose interested courses and participate in the online test. A task can start only after the tasks depends on have been completed. Authorized staff can set up the exam that: Requires a password to be accessed Has a set time after which the exam is automatically submitted Exams can be grouped under class headings i. Planning is setting out standards for tests. Here a detailed system study was carried out, checking the existing system to replicate it with our system.
Alternative course of action Alternative course of action A: if the posted result is wrong A. Gantt chart: Basic planning uses bar charts that show project activities and the amount of time they will take. Online examination system also allows to correct the answer if the examine needed to change any answer in the examination time duration, however, after the time duration any change will not allow. Teacher The teacher is one of the important entities for a school. When a program encounters an exception the default behavior is to throw the exception which generally translates to abruptly, terminating the program after displaying an error message. Yesterday I taught you on.
This result can be accessed by the institute to know the number of passes and fail students or to evaluate their performance in the exam. Finally Block: The finally block contains the code that always executes whenever or not any exception occurs. So we would wanna begin! The user consent is very important for the new plan. And we are needs number of computers with the same number of students. First, they have to login into the system and provide the old password and new password. Then the students search the posted questions by questionId.
The different levels of testing are shown in figure in next page. The system handles all the operation and generates reports as soon as the test is finish. While going through these books we enhanced our limited knowledge on these vast subjects which was not achieved through our semester papers. Security: the system security is one of the most important non-functional requirements. Now there are some organizational constraints that have not yet given us the opportunity to install the system.
If it describes both hardware and software, it is a system requirement specification. This table contains the student id from which we will help us in generating the result. But on the other hand Session increase congestion as the loads increase. A particular application may be technically and but may fail to produce the forecasted benefits, because the company is not able to get it to work. After design phase we can reduce the time required the implementation. Students can also take print of certificate later on too.
