CHAPTER 4 Other Non-functional Requirements Non-functional requirements, as the name suggests, are requirements that are not directly concerned with the specific services delivered by the system to its users. They may relate to emergent system properties such as reliability, response time, and store occupancy. Alternatively, they may define constraints on the system implementation such as the capabilities of I/O devices or the data representations used in interfaces with other systems. Non-functional requirements, such as performance, security, or availability, usually specify or constrain characteristics of the system as a whole.

4.1Usability:  The system provides a help and support menu in all interfaces for the user to interact with the system.  The user can use the system by reading help and support.

4.2Security:  The system provides username and password to prevent the system from unauthorized access.  The staffs’ password must be greater than eight characters.

4.3Performance:  The system response time for every instruction conducted by the user must not exceed more than a minimum of 10 seconds.  The system should have high performance rate when executing user’s input and should be able to provide response with in a short time span usually 50 second for highly complicated task and 20 to 25 seconds for less complicated task.

4.4Availability:  The system should always be available for access at 24 hours, 7 days a week. Also in the occurrence of any major system malfunctioning, the system should be available in 1 to 2 working days, so that business process is not severely affected. .

CHAPTER 5 Other Requirements Bharati Sojitra:110570107007 Dishika Baraiya:110570107022

CHAPTER 6 Testing 6.1 Testing Methods: Testing programs to establish the presence of system defects. Testing is required:    

To understand testing techniques that are geared to discover program faults. To introduce guidelines for interface testing. To understand specific approaches to object-oriented testing. To understand the principles of CASE tool support for testing.

There are several types of testing: 6.1.1

Component Testing:



Testing of individual program components.



Usually the responsibility of the component developer (except sometimes for critical systems).



Tests are derived from the developer’s experience.

6.1.2 Integration Testing:  Testing of groups of components integrated to create a system or sub-system.  The responsibility of an independent testing team.  Tests are based on a system specification 6.1.3 Defect Testing:  The goal of defect testing is to discover defects in programs  A successful defect test is a test which causes a program to behave in an anomalous way.  Tests show the presence not the absence of defects. 6.1.4 Black-box Testing:  An approach to testing where the program is considered as a ‘black-box’  The program test cases are based on the system specification  Test planning can begin early in the software process

6.2

Test Cases:

6.2.1 White Box Test Cases:  Guarantee that all independent paths within a module have been exercised at least once.  Exercise all logical decisions on their true and false sides.  Execute all loops at their boundaries and within their operational bounds.  Exercise internal data structures to ensure their validity. Bharati Sojitra:110570107007 Dishika Baraiya:110570107022

24

Online Car Rental System 6.2.2 Black Box Test Cases:  Incorrect or missing functions,  Interface errors,  Errors in data structures or external data base access.  Behavior or performance errors,  Initialization and termination errors.  Test cases that reduce the number of additional test cases that must be designed to achieve 

reasonable testing (i.e minimize effort and time). Test cases that tell us something about the presence or absence of classes of errors.
