Project Overview Review of Work for Phase I and Phase II Action items from phase II Assessment Evaluation Project Evaluation Lessons Learned Demo

Project Overview

The main objective of my MSE project was to design, code and test an Airline Reservation System website, which allows the users to purchase airline tickets and book motels and packages available to them.

This project is mainly developed for common people. General features provided by the website are:

register, Search and browsing, flight, package and hotel booking etc.

Review of work for phases I and II

Phase I Phase I of the vision document mainly was the

requirements specification phase where I have designed the vision document for the Airline Reservation System.

All the use cases planned in the vision document for the user have been implemented

Review of work for phases I and II continued..

Phase II The phase II of the project mainly consisted

of revising the documents from Phase I First working prototype was developed in this

phase Creation of Test Plan

Action Items from Phase II

The major action item from Phase II was the class diagram. I have corrected the class diagram and the correct diagram has been depicted in the Component Design document.

Action Items from Phase II

Assessment Evaluation

The Assessment Evaluation document is one of the Major deliverables of Phase III.

Two types of testing done on the Airline Reservation System application

- Manual Testing

- JMeter Performance Testing

Assessment Evaluation continued..

The manual testing was mainly performed to ensure correctness of the various parts of coding

Table: Customer pages test summary

TEST CASE # DESCRIPTION RESULTS/COMMENTS

TC # 1 User Login Passed

TC # 2 User Registration Passed

TC # 3 Search and Book Flights Passed

TC # 4 Search and Book Packages Passed

TC # 5 Search and Book Hotels Passed

Assessment Evaluation continued..

The sample test case for manual testing of customer pages is :

TEST UNIT TEST CASE RESULT

Flight booking Wrong format of information entered into the data fields of the flight booking page

The system generates an error message to the user indicating that the wrong format of data is entered and to re-enter the data.

Flight Booking Wrong date format, in the date of journey data field, wrong flight number in the Flight Number fields etc,

(similarly for all the other data fields of the Flight Search page)

The systems generates a message to the user saying that he has entered an invalid date format and incase of wrong flight number, indicates that his entry is invalid.

Flight Booking Correct format of data is entered into the data fields in the flight booking page.

The system allows the users to book the flight by providing details required and directs them to the booking confirmation page.

Assessment Evaluation continued..

The performance testing is mainly done to load test the web application.

The load is determined here in terms of the number of concurrent users of the website.

Determine the response time for the web page.

(Response time is the time taken by the server to bring up a requested page in the browser, beginning from the time it has been requested)

Assessment Evaluation continued..

The performance testing of the Airline Reservation System website was mainly done on three pages:

Home.aspx page Booking.aspx page FlightSearch.aspx page

Assessment Evaluation continued..

The tool used for performance testing is JMeter.

Input to the JMeter tool consist of :

Number of Threads/ Users Ramp-up period – time in seconds to load the total

number of users chosen Loop Count - number of times the test is to be repeated

Assessment Evaluation continued..

In my case I have tested the application for the following data:

No. of users = 100 No. of requests concurrently : 1000Ramp-up period = 10 Loop count = 10

Thread Count Ramp-Up Period Loop Count

100 10 10

Assessment Evaluation continued..

The throughput obtained for the three pages are:

WEB PAGE THROUGHPUT

Home page 100/sec

Login page 91.0/sec

Flight Search and Booking page 62.3/sec

Assessment Evaluation continued..

I also tested for heavy load on the application, where the database had about 5000 elements in the table.

Initially the response time for the page, when it had a less number of elements in the table was around 15 ms

But upon adding 5000 values to the table randomly and then repeating the same number of tests with J Meter the average response time for the Customer Details page shot up to 3699 ms.

The throughput for the page was also very less around 12.3 requests / sec

Assessment Evaluation continued..

Assessment Evaluation continued..

The environment used to performance test the application is as follows:

Operating System – Windows XP Professional Memory – 0.99 GB RAM 80 GB Hard Disk Intel® Pentium® M Processor 1.7 GHz

Project Evaluation

The actual duration of the project is :

Phase I – 61 hours

Phase II – 152 hours

Phase III – 225 hours

Total of 438 hours

BreakDown for each phase of the MSE project

Phase I14%

Phase II35%

Phase III51%

Phase I

Phase II

Phase III

Project Evaluation Continued..

Of the total hours spent on the project nearly 190 hours was dedicated to coding. Nearly 43.3% of the whole time was dedicated to coding the project.

Nearly 80 hours , that is nearly 20% of the time was spent on the documentation for the project.

Project Evaluation continued..

The total lines of code for the project is 4912 LOC.

Out of that

Lessons Learnt

I have had the chance to develop the project in a new technology.

I have come into touch with various tools like J Meter, SLOC count for counting the number of lines of code

I have developed a whole project, going through all the phases of the project.

To be ready for the unexpected
