CHAPTER FIVE: SYSTEM TESTING AND MAINTENANCE

5.1Overview

The chapters describe the way the website was implemented from the point of view

of testing and then maintaining it. The search queries that are built based on the flowcharts

mentioned in chapter three. The chapter includes the testing methodology used to perform

functional, load and performance testing. A survey questionnaire is designed to conduct

testing of UAE Jobs function and reliability. The numbers of users testing UAE Jobs were

10 users and all were successful showing good performance from the website.

This chapter also discusses the maintenance phase of the project as well as the

system review. System maintenance term refers to the actions of measuring the system

performance and availability in using multiple system measures such as the database size,

program units’ performance, database queries performance and system response time.

System maintenance includes two types of maintenance corrective maintenance and

preventive maintenance. In corrective maintenance, the system issues are explored,

reported, analyzed and fixed. In preventive maintenance, the system evaluated is on regular

basis in order to analyze and prevent any possible problem.

During the system review, the system evaluated is to find the answer of the

question of “Does the system satisfy the need of users?” System review activities require

the reviewer to use the measures of the performance conducted in system maintenance and

compare them to the other systems including the automated and manual ones.

5.2.2. Load Testing

The system was tested using Microsoft Application test center where 10 virtual users

were created and operated to run as 10 in parallel. The system response time in the

advanced search page was found to be 5 seconds. The system response time was not

affected by increasing the parallel users to 10 instead of 5.

5.2.3. Performance Testing

The testing of performance covers the following type of testing1 where 10 users

have conducted it validating the performance of UAE Jobs functioning:

Module or unit testing: Individual modules are tested to ensure that they

function correctly for given inputs. Here, the users have tested each module of

UAE Jobs such as About US, Home, Career Services, Seeker, Employer and

Contact Us pages.

System testing: When all modules have been completed and their interactions

assessed for validity, links between all modules are assessed in the system test.

In system testing, interactions between all relevant modules are tested

systematically. The users of UAE Jobs were able to browse links showing and

proving connectivity of each of the modules in UAE Jobs. They were able to

interact assessing the validity of the links.

Regression testing: Testing performed before a release to ensure that the

software performance is consistent with previous test results, i.e. that the

outputs produced are consistent with previous releases of the software. The

expected output of UAE Jobs is consistent with users test results. 1 http://fjdoyle.dit.ie/Business%20Information%20Systems%20slides/BIS%2012%20Build,%20Implement,%20Maintain.ppt

access or modify another user of UAE Jobs information either employer or job

seeker.

5.5 Obtain maintenance request

During the first days of running the application, users reported that the validations

on the inputs are not working properly such that the experience field allows alphabet

characters to be entered which cause an error during saving the job seeker profile.

5.6 Transform requests into changes

The reported issue of validation was analyzed and verified. The issue is

documented in an issue tack record that is shown in table 5-5.1.

Issue Id ISU-01 Reported At 15 April 2012Issue Name Number of Experience

Years ValidationReported By Anonymous User

Issue Description The field of Number of years of experience in Seeker registration page allows the user to enter non-numeric characters which causes the system to crash and does not register the user.

Suggested Resolution Add regular expression validation of ASP.NET with the expression ^([0-9])+([0-9]*)$

Table 5.6-4: Validation Issue Tracking Record

5.7 Design changes

The reported issue resulted in a very minor design change as all pages free user

inputs are linked with ASP.NET regular expression validators and validation summary.

5.8 Implement changes

The minor design change was implemented as the fields validations are added to be

reported in red color to the user and does not allow the page to move to the database

function until all fields are valid which prevented the system crashes.
