Requirement Analysis At the heart of system analysis is a detailed understanding of all important facets of business area under investigation. (For this reason, the process of acquiring this is often termed the detailed investigation) Analyst, working closely with the employees and managers, must study the business process to answer these key questions:



hat is being done!



"ow is it being done!



"ow frequent does it occur!



"ow great is the volume of transaction or decisions!



"ow well is the task being performed!



#oes a problem e$ist!



%f a problem e$ists, how serious is it!



%f a problem e$ists, what is the underlying cause!

&equirement analysis relies on fact'finding techniques. hese include:

A feasibility study is conducted to select the best system that meets performance requirement. his entails an identification description, an evaluation of candidate system and the selection of best system for he +ob. he system required performance is defined by a statement of constraints, the identification of specific system ob+ective and a description of outputs.

he key consideration in feasibility analysis is:

. Economic Feasibility:

2. Technical Feasibility:

3. Operational Feasibility:

Economical feasibility

37

Department of Computer Science %t looks at the financial aspects of the pro+ect. %t determines whether the management has enough resources and budget to invest in the proposed system and the estimated time for the recovery of cost incurred. %t also determines whether it is worth while to invest the money in the proposed pro+ect. -conomic feasibility is determines by the means of cost benefit analysis. he proposed system is economically feasible because the cost involved in purchasing the hardware and the software are within approachable. he personal cost like salaries of employees hired are also nominal, because working in this system need not required a highly qualified professional. he operating'environment costs are marginal. he less time involved also helped in its economical feasibility. %t was observed that the organiation has already using computers for other purpose, so that there is no additional cost to be incurred for adding this system to its computers. he backend required for storing other details is also the same database that is /ql. he computers in the organiation are highly sophisticated and don0t needs e$tra components to load the software. "ence the organiation can implement the new system without any additional e$penditure. "ence, it is economically feasible.

"ere the /ystem testing involved is the most widely used testing process consisting of five stages as shown in the figure. %n general, the sequence of testing activities is component testing, integration testing, and then user testing.

"owever, as

defects are discovered at any one stage, they require program modifications to correct them and this may require other stages in the testing process to be repeated.

Department of Computer Science esting is the process of detecting errors. esting performs a very critical role for quality assurance and for ensuring the reliability of the software. he results of testing are used later on during maintenance also.

esting is vital to the success of the system. /ystem testing makes a logical assumption that if the parts of the system are correct, the goal will be successfully achieved. %n adequate testing or non'testing leads to errors that may not appear until months or even years later (&emember the >ew Dork three day power failures due to a misplaced Ereak0 statement).

his creates two problems: .

he time lag between the cause and the appearance of the problem.

3.

he time interval effect of the system errors on files and the records on the system.

A small error can conceivably e$plode into a much larger problem. -ffective testing early in the process translates directly into long term cost savings from a reduced number of errors.

Another reason for system testing is it0s utility as a user oriented vehicle before implementation. he best program is worthless if it does not meet the user requirements. Cnfortunately, the user0s demands are often compromised by efforts to facilitate program or design efficiency in terms of processing time or design efficiency.

62

Department of Computer Science hus in this phase we went to test the code we wrote. e needed to know if the code compiled with the design or not! hether the code gave the desired outputs on given inputs! hether it was ready to be installed on the user0s computer or some more modifications were needed!

hrough the web applications are characteristically different from there software counterparts but the basic approach for testing these web applications is quite similar. hese basic steps of testing have been picked from software engineering practices. he following are the steps, we undertook:

. he content of the %ntranet site is reviewed to uncover Bontent -rrors. Bontent -rrors covers the typographical errors, grammatical errors, errors in content consistency, graphical representation and cross referencing errors

3. he design model of the web application is reviewed to uncover the navigation errors. Cse cases, derived as a part of the analysis activity allows a web designer to e$ercise each usage scenario against the architectural and navigational design. %n essence these non'e$ecutable tests help to uncover the errors in navigation.

;. hen web applications are considered the concept of unit changes. -ach web page encapsulates content navigation links, content and processing elements (Forms, /cripts, and
63

Department of Computer Science 6. each of these individually. hus is the base of the web applications the unit to be considered is the web page. Cnlike the testing of the algorithmic details of a module the data that flows across the module interface, page level testing for web applications is driven by content, processing and links encapsulating the web page.

5.

he Assembled web application is tested for overall functionality and content delivery. he various user cases are used that test the system for errors and mistakes.

. he eb application is tested for a variety of environmental settings and is tested for various configurations and upon various platforms. he modules are integrated and integration test are conducted.

G. hread based testing is done to monitor the regression tests so that the site does not become very slow is a lot of users are simultaneously logged on.

8. A controlled and monitored population of end users tests %ntranet application, this all comprises of the Cser Acceptance esting.

ecause web applications evolve continuously, the testing process is an ongoing activity, conducted by web support staff in our case the *rganiation0s %/ people who will finally update and manage the application .

Department of Computer Science S45O'O64 OF TEST76

he aim of testing is often to demonstrate that a program works by showing that it has no errors. he basic purpose of testing phase is to detect the errors that may be present in the program. "ence one should not start testing with the intent of showing that a program works, but the intent should be to show that a program doesn0t work. esting is the process of e$ecuting a program with the intent of finding errors.

he main ob+ective of testing is to uncover a host of errors, systematically and with minimum effort and time. /tating formally, we can say, esting is a process of e$ecuting a program with the intent of finding an error. A successful test is one that uncovers an as yet undiscovered error. A good test case is one that has a high probability of finding error, if it e$ists. he tests are inadequate to detect possibly present errors. he software more or less confirms to the quality and reliable standards.

'E!E'S OF TEST76

%n order to uncover the errors present in different phases, we have the concept of levels of testing. he basic levels of testing are

Cnit testing focuses verification effort on the smallest unit of software i.e. the module. Csing the detailed design and the process specifications, testing is done to uncover errors within the boundary of the module. All modules must be successful in the unit test before the start of the integration testing begins. %n this pro+ect each service can be thought of a module. here are so many modules like 2ogin, "& #epartment, %nterviewer /ection, etc. -ach module has been tested by giving different sets of inputs. hen developing the module as well as finishing the development, the module works without any error. he inputs are validated when accepting them from the user. 66


nte0ration Testin0

After unit testing, we have to perform integration testing. he goal here is to see if modules can be integrated properly, the emphasis being on testing interfaces between modules. his testing activity can be considered as testing the design and hence the emphasis on testing module interactions.

%n this pro+ect the main system is formed by integrating all the modules. hen integrating all the modules % have checked whether the integration effects working of any of the services by giving different combinations of inputs with which the two services run perfectly before %ntegration.

Acceptance esting is performed with realistic data of the client to demonstrate that the software is working satisfactorily. esting here is focused on e$ternal behavior of the systemH the internal logic of program is not emphasied.

est cases should be selected so that the largest number of attributes of an equivalence class is e$ercised at once. he testing phase is an important part of software development. %t is the process of finding errors and missing operations and also a complete verification to determine whether the ob+ectives are met and the user requirements are satisfied.

his is a unit testing method, where a unit will be taken at a time and tested thoroughly at a statement level to find the ma$imum possible errors.

% tested step wise every piece of code, taking care that every statement in the code is e$ecuted at least once. he white bo$ testing is also called 7lass o$ esting.

% have generated a list of test cases, sample data, which is used to check all possible combinations of e$ecution paths through the code at every module level.

his testing method considers a module as a single unit and checks the unit at interface and communication with other modules rather getting into details at statement level. "ere the module will be treated as a block that will take some input and generate output. *utput for a given set of input combinations are forwarded to other modules. lack'bo$ test are designed to uncover errors functional requirement without regard to the internal workings of a program. lack'bo$ testing techniques focus on the information domain of the software, deriving test cases by partitioning the input and output domain of a program in manner that provides through test coverage. he black'bo$ test is used to demonstrate that software functions are operational, that input is properly produced, and that the integrity of e$ternal information are maintained. A black'bo$ test e$amines some fundamental aspect of a system with little or no regard for the integral logical structure of the software.

Department of Computer Science A strategy for software testing may also be viewed in the conte$t of the spiral. Cnit testing begins at the vorte$ of the spiral and, concentrates on each unit, component of the software as implemented in source code. esting progresses moving outward along the spiral to integration testing, where the focus is on designed the construction of the software architecture. aking another turn outward on spiral, Bonsidering the process from a procedural point of view, testing within the conte$t of software engineering is actually a series of four steps that are implemented sequentially. he steps are shown in Figure. %nitially, tests focus on each component individually, ensuring that it functions properly as unit. "ence, the name unit testing. Cnit testing makes heavy use of white'bo$ testing techniques, e$ercising specific paths in module0s control structure to ensure complete coverage and ma$imum error detection.
