Abstract

AUTOMATED TEST SYSTEMis a software application to automate the test taking

procedure at various institutes that provide testing facilties at various levels. This system will

provide a basis for effective fulfillment of conducting Automated tests as a replacement for the

paper based tests which are conducted during the internals in the college. It is a generic

software which is not specifically for MMU. but can be used by any college, school or institute.

It can be operated easily even by new users, as it uses interactive menus, frames, buttons etc. It

is not required for the user to have any special knowledge. It has a simple interface and the user

does not need to have any prior knowledge to access the system.

This project has been made using Java.It uses MS Access for creating the database. The

following Packages of Java are used in the project:

Java.sql

Java.awt

Java.awt.event

import javax.swing.

A Package in Java is a group of related classes,interfaces and sub-packages.

It uses Frame class which is a sub-class of the Window class.It is used to create a GUI

application window.

The creation of JAVA

Java was conceived by James Gosling, Patrick Naughton, Chris Warth, Ed Frank, and

Mike Sheridan at Sun Microsystems, Inc. in 1991. It took 18 months to develop the firstworking version. This language was initially called Oak but was renamed Java

in 1995. Between the initial implementation of Oak in the fall of 1992 and the public

announcement of Java in the spring of 1995, many more people contributed to the design

and evolution of the language. Bill Joy, Arthur van Hoff, Jonathan Payne, Frank Yellin,

and Tim Lindholm were key contributors to the maturing of the original prototype.

Somewhat surprisingly, the original impetus for Java was not the Internet! Instead,

the primary motivation was the need for a platform-independent (that is, architecture-

neutral) language that could be used to create software to be embedded in various

consumer electronic devices, such as microwave ovens and remote controls. As you

can probably guess, many different types of CPUs are used as controllers. The trouble

with C and C++ (and most other languages) is that they are designed to be compiled

for a specific target. Although it is possible to compile a C++ program for just about

any type of CPU, to do so requires a full C++ compiler targeted for that CPU. The

problem is that compilers are expensive and time-consuming to create. An easier

and more cost-efficientsolution was needed. In an attempt to find such a solution,

Gosling and others began work on a portable, platform-independent language that

could be used to produce code that would run on a variety of CPUs under differing

environments. This effort ultimately led to the creation of Java.

Why JAVA is important to Internet

6 | P a g e


7/64


The Internet helped catapult Java to the forefront of programming, and Java, in turn, has had a

profound effect on the Internet. The reason for this is quite simple: Java expands the universe of

objects that can move about freely in cyberspace. In a network, two very broad categories of

objects are transmitted between the server and your personal computer: passive information and

dynamic, active programs. For example, when you read your e-mail, you are viewing passive

data. Even when you download program, the programs code is still only passive data until you

execute it. However, second type of object can be transmitted to your computer: a dynamic,

self-executing program. Such a program is an active agent on the client computer, yet is

initiated by the server. For example, a program might be provided by the server to display

properly the data that the server is sending.

As desirable as dynamic, networked programs are, they also present serious

problems in the areas of security and portability. Prior to Java, cyberspace was

effectively closed to half the entities that now live there. As you will see, Java addresses

those concerns and, by doing so, has opened the door to an exciting new form of

program: the applet.

JAVA Applets & Applications:

Java can be used to create two types of programs: applications and applets. An

application is a program that runs on your computer, under the operating system of that

computer. That is, an application created by Java is more or less like one created using C

or C++. When used to create applications, Java is not much different from any other

computer language. Rather, it is Javas ability to create applets that makes it important.

An appletis an application designed to be transmitted over the Internet and executed by

a Java-compatible Web browser. An applet is actually a tiny Java program, dynamically

downloaded across the network, just like an image, sound file, or video clip. The

important difference is that an applet is an intelligent program, not just an animation or

media file. In other words, an applet is a program that can react to user input and

dynamically changenot just run the same animation or sound over and over.

As exciting as applets are, they would be nothing more than wishful thinking if

Java were not able to address the two fundamental problems associated with them:

security and portability. Before continuing, lets define what these two terms mean

relative to the Internet.

Java was designed to be easy for the professional programmer to learn and use

effectively. Assuming that you have some programming experience, you will not find

Java hard to master. If you already understand the basic concepts of object-oriented

programming, learning Java will be even easier. Best of all, if you are an experienced

C++ programmer, moving to Java will require very little effort. Because Java inherits

the C/C++ syntax and many of the object-oriented features of C++, most programmers

have little trouble learning Java. Also, some of the more confusing concepts from C++

are either left out of Java or implemented in a cleaner, more approachable manner.

Beyond its similarities with C/C++, Java has another attribute that makes it easy

to learn: it makes an effort not to havesurprisingfeatures. In Java, there are a small

number of clearly defined ways to accomplish a given task.

Security:

As you are likely aware, every time that you download a normal program, you

are risking a viral infection. Prior to Java, most users did not download executable

programs frequently, and those who did scanned them for viruses prior to execution.

Even so, most users still worried about the possibility of infecting their systems with

a virus. In addition to viruses, another type of malicious program exists that must be

guarded against. This type of program can gather private information, such as credit

card numbers, bank account balances, and passwords, by searching the contents of

your computers local file system. Java answers both of these concerns by providing

a firewall between a networked application and your computer.

When you use a Java-compatible Web browser, you can safely download Java

applets without fear of viral infection or malicious intent. Java achieves this protection

by confining a Java program to the Java execution environment and not allowing it

access to other parts of the computer. (You will see how this is accomplished shortly.)

The ability to download applets with confidence that no harm will be done and that

no security will be breached is considered by many to be the single most important

aspect of Java.

Portability:

As discussed earlier, many types of computers and operating systems are in use

throughout the worldand many are connected to the Internet. For programs to

be dynamically downloaded to all the various types of platforms connected to the

Internet, some means of generating portable executable code is needed. As you will

soon see, the same mechanism that helps ensure security also helps create portability.

Indeed, Javas solution to these two problems is both elegant and efficient.

Object Oriented

Although influenced by its predecessors, Java was not designed to be source-code

compatible with any other language. This allowed the Java team the freedom to design

with a blank slate. One outcome of this was a clean, usable, pragmatic approach to

objects. Borrowing liberally from many seminal object-software environments of the

last few decades, Java manages to strike a balance between the purists everything is

an object paradigm and the pragmatists stay out of my way model. The object

model in Java is simple and easy to extend, while simple types, such as integers, are

kept as high-performance nonobjects.

Robust

The multiplatformed environment of the Web places extraordinary demands on a

11 | P a g e


12/64


program, because the program must execute reliably in a variety of systems. Thus, the

ability to create robust programs was given a high priority in the design of Java. To

gain reliability, Java restricts you in a few key areas, to force you to find your mistakes

early in program development. At the same time, Java frees you from having to worry

about many of the most common causes of programming errors. Because Java is a

strictly typed language, it checks your code at compile time. However, it also checks

your code at run time. In fact, many hard-to-track-down bugs that often turn up in

hard-to-reproduce run-time situations are simply impossible to create in Java.

Knowing that what you have written will behave in a predictable way under diverse

conditions is a key feature of Java.

To better understand how Java is robust, consider two of the main reasons for

program failure: memory management mistakes and mishandled exceptional

conditions (that is, run-time errors). Memory management can be a difficult, tedious

task in traditional programming environments. For example, in C/C++, the

programmer must manually allocate and free all dynamic memory. This sometimes

leads to problems, because programmers will either forget to free memory that has

been previously allocated or, worse, try to free some memory that another part of

their code is still using. Java virtually eliminates these problems by managing memory

allocation and deallocation for you. (In fact, deallocation is completely automatic,because Java provides garbage collection for unused objects.) Exceptional conditions in

traditional environments often arise in situations such as division by zero or file not

found, and they must be managed with clumsy and hard-to-read constructs. Java

helps in this area by providing object-oriented exception handling. In a well-written

Java program, all run-time errors canand shouldbe managed by your program.

Multithreaded

Java was designed to meet the real-world requirement of creating interactive,

12 | P a g e


13/64


networked programs. To accomplish this, Java supports multithreaded programming,

which allows you to write programs that do many things simultaneously. The Java

run-time system comes with an elegant yet sophisticated solution for multiprocess

synchronization that enables you to construct smoothly running interactive systems.

Javas easy-to-use approach to multithreading allows you to think about the specific

behavior of your program, not the multitasking subsystem.

Architectural Neutral

A central issue for the Java designers was that of code longevity and portability. One

of the main problems facing programmers is that no guarantee exists that if you write

a program today, it will run tomorroweven on the same machine. Operating system

upgrades, processor upgrades, and changes in core system resources can all combine

to make a program malfunction. The Java designers made several hard decisions in the

Java language and the Java Virtual Machine in an attempt to alter this situation. Their

goal was write once; run anywhere, any time, forever. To a great extent, this goal

was accomplished.

Interpreted & high performance

As described earlier, Java enables the creation of cross-platform programs by compiling

into an intermediate representation called Java bytecode. This code can be interpreted

on any system that provides a Java Virtual Machine. Most previous attempts at cross-

platform solutions have done so at the expense of performance. Other interpreted

systems, such as BASIC, Tcl, and PERL, suffer from almost insurmountable performance

deficits. Java, however, was designed to perform well on very low-power CPUs. As

explained earlier, while it is true that Java was engineered for interpretation, the Java

bytecode was carefully designed so that it would be easy to translate directly into native

machine code for very high performance by using a just-in-time compiler. Java run-time

systems that provide this feature lose none of the benefits of the platform-independent

13 | P a g e


14/64


code. High-performance cross-platform is no longer an oxymoron

Distributed

Java is designed for the distributed environment of the Internet, because it handles

TCP/IP protocols. In fact, accessing a resource using a URL is not much different

from accessing a file. The original version of Java (Oak) included features for intra-

address-space messaging. This allowed objects on two different computers to execute

procedures remotely. Java revived these interfaces in a package calledRemote Method

Invocation (RMI). This feature brings an unparalleled level of abstraction to client/server programming.

Dynamic

Java programs carry with them substantial amounts of run-time type information that

is used to verify and resolve accesses to objects at run time. This makes it possible to

dynamically link code in a safe and expedient manner. This is crucial to the robustness of the

applet environment, in which small fragments of bytecode may be dynamically

updated on a running system.

JDBC Connectivity-Java Database Connectivity

14 | P a g e


15/64


JDBC is Java application programming interface that allows the Java programmers to access

database management system from Java code.

In short JDBC helps the programmers to write java applications that manage these three

programming activities:

1. It helps us to connect to a data source, like a database.

2. It helps us in sending queries and updating statements to the database.

3. Retrieving and processing the results received from the database in terms of answering to

your query.

Database:

A database is an organized collection of information. A simple example of a database are like your

telephone directory, recipe book etc.

A Relational model is the basis for any relational database management system (RDBMS). A relational

model has mainly three components:

1. A collection of objects or relations,.

2. Operators that act on the objects or relations.

3. Data integrity methods.

To design a database we need three things:

1. Table

2. Rows

3. Columns

SOFTWARE DEVELOPMENT LIFE CYCLE

15 | P a g e


16/64


The Systems Development Life Cycle (SDLC), orSoftware Development Life

Cycle in systems engineering, information systems and software engineering, is the process of

creating or altering systems, and the models and methodologies that people use to develop these

systems. The concept generally refers to computer or information systems. Emphasis on this

article (SDLC) is on man-made technological life-cycle. But there are many other life-cycle

models to choose from. This includes ecological life cycles, for every life cycle, whether

biological or technological, has a beginning and an end.

In software engineering the SDLC concept underpins many kinds of software development

methodologies. These methodologies form the framework for planning and controlling the

creation of an information system[1]: the software development process.

In project management a project can be defined both with a project life cycle (PLC) and an

SDLC, during which slightly different activities occur. According to Taylor (2004) "the project

life cycle encompasses all the activities of the project, while the systems development life cycle

focuses on realizing the product requirements".

Figure:3 Model of the Systems Development Life Cycle

16 | P a g e

with the Maintenance bubble highlighted.

The System Development Life Cycle framework provides a sequence of activities for

system designers and developers to follow. It consists of a set of steps or phases in which each

phase of the SDLC uses the results of the previous one.

A Systems Development Life Cycle (SDLC) adheres to important phases that are essential for

developers, such as planning, analysis, design, and implementation, and are explained in the

section below. A number of system development life cycle (SDLC) models have been created:

waterfall, fountain, spiral, build and fix, rapid prototyping, incremental, and synchronize andstabilize. The oldest of these, and the best known, is the waterfall model: a sequence of stages

in which the output of each stage becomes the input for the next. These stages can be

characterized and divided up in different ways, including the following:

Project planning, feasibility study: Establishes a high-level view of the

intended project and determines its goals.

Systems analysis, requirements definition: Defines project goals into

defined functions and operation of the intended application. Analyzes end-user

information needs.

Systems design: Describes desired features and operations in detail,including screen layouts, business rules, process diagrams, pseudocode and

other documentation.

Implementation: The real code is written here.

17 | P a g e


18/64


Integration and testing: Brings all the pieces together into a special testing

environment, then checks for errors, bugs and interoperability.

Acceptance, installation, deployment: The final stage of initialdevelopment, where the software is put into production and runs actual

business.

Maintenance: What happens during the rest of the software's life: changes,

correction, additions, moves to a different computing platform and more. This,

the least glamorous and perhaps most important step of all, goes on seemingly

forever.

Introduction to Automated Test System

Automated Test System is basically intended at developing software for providing anAutomated System for the students of MMU. We will be developing this software because of

the following reasons:

1. Presently, if the teachers conduct any objective test, they have to check the answersheets manually which is time consuming.

2. Students cannot do practice of attempting objective question papers.

3. Generation of results manually might result in errors. The Automated Test System willbe overcoming the above mentioned problems and will be providing the following

features:

4. There will be a real time testing environment.

18 | P a g e


19/64


5. Test creation will become easier which will be including incorporation of new questionsand deletion and modification of already existing questions periodically.

6. Paper pattern which includes duration of test, number of questions of various levels andmarking scheme; will have flexibility, i.e. faculty will have such options.

7. Results and the answers will be displayed instantaneously just after the completion oftest.

8. The records of the students will be updated in their profile after the completion of theirtest for future references.

9. There will be different level of questions in the paper so that the judgement of studentsknowledge can be done efficiently.

10. There will be zero paper work.

11. The students will have to get themselves registered before they proceed further.

Background

EXISTING SYSTEM

The whole process of assigning test and evaluating their scores after the test, was done

manually till date. Processing the test paper i.e. checking and distributing respective scores used

to take time when the software was not installed.

19 | P a g e


20/64


DISADVANTAGES OF CURRENT

SYSTEM

The current system is very time consuming.

It is very difficult to analyze the exam manually.

To take exam of more candidates more invigilators are required but no need of

invigilator in case of on line exam.

Results are not precise as calculation and evaluations are done manually.

The chances of paper leakage are more in current system as compared to proposed

system.

Result processing takes more time as it is done manually

System Model

Automates Test System will provide a basis for effective fulfillment of conducting Automated

tests as a replacement for the paper based tests which are conducted during the internals in the

college. It is a generic software which is not specifically for MMU. but can be used by any

college, school or institute. The only necessary condition for the usage of this software is that

there should be following users:

20 | P a g e


21/64


Administrator: He is the person who will be responsible for maintaining the whole system. He

will have access to the profile of every student which will give the record of the performance of

that student in various tests he gave. He will be provided with the effective test system

supervision. In case the system works only as a practice session the result is not stored in the

database ans hence can't be accessed for any further use. This part of the system is enhanced

when used in major exam taking institutes.

User: He is the person who will be appearing in the test which will be conducted by the faculty.

He will know his result instantaneously. Before all this, he will have to register himself or fill

login-id and password if already registered. The person has to select for which he is giving the

exam and selects ot and appears for it .The exam result is shown when the user completed the

exam.

PROJECT SCREEN AND ITS IMPLEMENTATION

54 | P a g e


55/64


Figure 1 Login screen of Automated Test System

This is the login screen of the system. Here the administrator gives the username and

password .The default username that has been set is admin and password is admin. This is

only for security purpose. If the user is admin then he has to check administrator and other

cases the subject is slected and user(student) filles its username and password

55 | P a g e


56/64


Figure 2 Home screen of Automated Test system

This screen is the home screen of the automated test system in case the user is admin.. This

screen is used to access all the features of the automated test system. The admin can add

question to the database the user answers and can register new user .

56 | P a g e


57/64


Figure 3 Add question

This screen is the admin panel in which the admin can add question to the system .The question

once added to the system can only be edited in the database. Question added are stored in the

table in database The admin fills out the various options.

57 | P a g e


58/64


Figure 4 Adding student details

This screen is the admin panel in which the admin can add a new user which is students who

appears for the test. The admin here fills out all the necessary details of the students which are

necessary to recognize him later.

The password is set by the admin to secure the system.

58 | P a g e


59/64


Figure 5 Screen at the start of the test

The screen is displayed at the starting with all the exam instruction..The time counter begins

when u hit the "start" key . In this screen a user named Nitin is shown giving exam.

59 | P a g e


60/64


Figure 6 Screen showing error.

In case the user selects two option an error message is displayed asking to tick only one option.

This is one of the constraint that has been applied to the system. This constraint make sure that

the students doesn't check out all the answer and only one answer is given for each question.

60 | P a g e


61/64


Figure 7 Screen showing result after completion.

This window is displayed at the end of the test to show the result. In the following system the

results are not stored in the database as it is just for practice of the user and to understand his

lag areas' proper percentage is calculated acc to answers that are answered correctly.

61 | P a g e


62/64


SCOPE:

The Automated Test System is having the following scope:

1. It can be used by the institute itself for conducting objective tests of various subjects.

2. It is generic software, so it can be used by various other institutes, schools and colleges.

3. The students nowadays face so many competitive exams which are objective. So they can

prepare themselves by using this software personally.

Even if the faculty doesnt want to conduct test online, then he can at least keep question bank

and modify it by using this software.

ADVANTAGES:

Use full for a rural students, where they can improve their knowledge and come across about

automated examination.

Improves concentration.

User friendly.

User information is maintained.

Cost effective.

Data validation is done during data entry itself so that errors are minimized.

62 | P a g e


63/64


Conclusion

The Automated test System is developed using Java and Ms Access fully meets the objectives

of the system for which it has been developed. The system has reached a steady state where all

bugs have been eliminated. The system is operated at a high level of efficiency and all the

teachers and user associated with the system understands its advantage. The system solves the

problem. It was intended to solve as requirement specification.
