Block 4 p5

Question 1

What is thr only way to ensure the web application is working

Answer 1

To test it

Question 2

The types of testing

Answer 2

Functionality testing: verify if the web pages are functional, check hyperlinks, data collection forms…

Usability testing: ensure that the application is easy to use

Accessibility testing: ensure the app is accessible to all users

interface testing : cooperation between app and database servers

Compatobility testing: working regardless of browser and os and hardware

performance testing: ability for servers to respond to jser demand

Sercurity testing: ensure app implements authentication and authorisation controls

Regression testing: software testing to uncover defects

Question 3

What is Unit test and what should it cover

Answer 3

verify small execution of small pieces of code

Should cover :
XHTML validation
CSS validation
Forms
Internela hyperlinks
Client side obj and funct
Server side obj snd funct
Database queries

Question 4

What is integration tests

Answer 4

verify that individual units work together (for typical web app testing functionality , usability, browser, compatibility, accessibility)

Question 5

What is usability tests and whay are the potential erros

Answer 5

conducted to identify usability issues in ui and content areas

Some errors include
navigation errors : fail to locste fucntions , too many keystroke
Presentation errors : failure to locate important information on the page
Control usage problems : incorrect use of buttons, tabs, toolbars failure to enter data in correct field

Question 6

What are functional tests

Answer 6

designed arround specific tasks, user registration , catalogue search and will highlight integration problems between the client and server

Question 7

What are system tests , what are its goal

Answer 7

verify performance of the app in its final configuration and verify integration with otherbhardware or software systems - it is conductiled on a dedicated set of equipment

the goal of these tests is to establish:
that the system meet planned response times for a given load
sydtem remains stable under high load

(load js the number if simultaneous users accessing web apps)

Question 8

What are the three types of system tests

Answer 8

load test: determine response time for a function

Stress test: assess performance of app when load exceedds the expexted usage - goal thay the system remains reliable

Capacity test: know the maximum number of users the app can support reliably

Question 9

what are aceptance tests

Answer 9

final phase of testing in v model lifecycle
verify the web browser fulfild thr user requirements that were established , the client should perform the acceptance test

Question 10

What are the critic areas for client involvmemt

Answer 10

function: app fulfils the functional requirements
Usability: confirm that end user can get information quickly and easily , onscreen instructions are understandable
Work flow: sequence of web pages of an application match the underlying process flow

HIGH risk functionality must be tezting but low risk ones can be skipped

Question 11

Manual testing and Automated testing

Answer 11

knowing the best way to perform the tests can be as important as the tests themselves

Manual testing: flexibility of the human operator

Automating: create a program to process the web page extract all the tags request the resource and record the outcome

Question 12

What are some automation tools

Answer 12

Selenium and Watir to test local files
JMeter requires that the target files are hosted on a web browser

Question 13

Advantages and disadvantages of manual testing

Answer 13

Advantages
-basic function tests can be completed with just a browser ,
-operators can process multi language applications
-find a wide range of errors by thinking outside of the box
-Quick to initiate tests by making use of operators intelligence

Disadvantages:
-op may restrict tests to those specified
-Slow to exexute all possible paths
-inconsistent results from user input errors
-Difficult to test performance of the server because real users cant generate sufficient load

Question 14

Advantages and Disadvantages of automatic testing

Answer 14

Advantages :
fast, repeatable
consistent result
can create high loads
extensive record keeping of test result
better management of complex test sets
Disadvantages:
Software licence
software instalation administration and maintenance
Time required to learn and test tools
Tests restricted to.whatever is contained in the program

Question 15

What are test environments

Answer 15

configuration of clients, servers, and network

Question 16

who is responsible of unit testingnand version control

Answer 16

developers

Question 17

what does isolating the network do

Answer 17

protects the test env from application and configuration errors and maximise the available bandwith

Question 18

Is the production env also a test env

Answer 18

No and it should never be used as one

Question 19

What is a test plan

Answer 19

document that sets out the objectives , respinsibilities and reporting methods related to testing

Question 20

What are the key sections of a test plan

Answer 20

Introduction: sumary about the web app

Obejctives: purpose of the tests to be conducted

Test methods: main ohases of testing, type of tests, how it will be conducted (automatoc, manual)

Responsibilitiea: details of the people and the tests theybare responsible of

Test env: resources required to test within tbe planned schedule

Error reporting: details aboug funct errors during testing

Schedule: planned testing acticity and risks that might delay

Appendices: references to other project documents

Question 21

When is preparation is started

Answer 21

as soon as the user req have been agreed
