In this post I am gonna give answer to reader’s question.
There was one question asked by Srividya:
Q.What is difference between client server and Web Testing?
Vijay: Well Srividya I would like to add one more testing type i.e Desktop Testing in this discussion. So now we have three testing types Desktop application testing, Client server application testing and Web application testing.
Each one differs in the environment in which they are tested and you will lose control over the environment in which application you are testing, while you move from desktop to web applications.
Desktop application runs on personal computers and work stations, so when you test the desktop application you are focusing on a specific environment. You will test complete application broadly in categories like GUI, functionality, Load, and backend i.e DB.
In client server application you have two different components to test. Application is loaded on server machine while the application exe on every client machine. You will test broadly in categories like, GUI on both sides, functionality, Load, client-server interaction, backend. This environment is mostly used in Intranet networks. You are aware of number of clients and servers and their locations in the test scenario.
Web application is a bit different and complex to test as tester don’t have that much control over the application. Application is loaded on the server whose location may or may not be known and no exe is installed on the client machine, you have to test it on different web browsers. Web applications are supposed to be tested on different browsers and OS platforms so broadly Web application is tested mainly for browser compatibility and operating system compatibility, error handling, static pages, backend testing and load testing.
I think this will have an idea of all three testing environment. Keep in mind that even the difference exist in these three environment, the basic quality assurance and testing principles remains same and applies to all.

Hi,
interesting……..thanks keep us updated
Thanks… its a good one and more interesting
Can u give an example for client server application
thanks for valuable info
I am feeling very happy while readying web site testing and i got good knowledge on three different applications of desktop,client server and web.plz maintain updation which are very useful for freshers and experience candidates.
Thanx for valuable information.
i am Very glad to read the givem materail on web testing but want some more knowledge .
i am Very glad to read the givem materail on web testing but want some more knowledge plz send me some more info….
thank u very much…..
Thanx for giving these informations..
hi Vijay,
Thank U very much, for writing such a nice article.
Hi vijay,
There is no confusion in this article, every thing s fine. I would like to know what s a normal application,could u tell me a with a siple example.
hi vijay,
this is very good and and vey easy to understand .
thanx for giving this much good notes.
thanks for valuable info

How i can fill HTML hidden text box from my WinRunner?
Please help me.
Great Info
This site has answered to many questions I was looking for many days.
Thanks to author
Must say great collection…………….
I read some of the comments pposted on this website about tesing and principles. I think it is one of the better sites today.

Its nice,Thank u!!!!!!!
hi…
Iam very much thankfull to u.This answer wiil be help full for all those who want’s to try a job on testing.
Hi,
I am not convinced with your answer. so many flaws but a nice attempt. be clear in addressing, most people refer this site as a tool to enrich their knowledge.
How we approach V-Model in our development Project
DeskTop Application : Example Yahoo Messenger. Never updates automatically. U have to run the updates always.
Client Server Application : Its always connect to the server if any changes in application its automatically reflect in the application.
Thanks for valuable information.ok
byeeeeee
keepsmiling
what type of testing is genraly use in practical ?
anyone plz give me example for desktop application. is yahoo messenger so.but how?
@rahini..
MSPAINT.,,,tart–>program File–>Acceseries–>address book
all are example of desktop appication ..
@rahini..
MSPAINT.,,,start–>program File–>Acceseries–>address book
all are example of desktop appication ..
thanks rahul,
then yahoo messanger is desktop application or web application.plz explain me.
coz yahoo messenger application resides in client’s machine and also it will contact server also to exchange information packets. so here am confused whether its client-server or desktop application
@Rahini on
Destop app–exe reside on local pc..
C/S appll– —Application is loaded on server machine while the application exe on every client machine.
Web Appli—Application is loaded on the server whose location may or may not be known(Mainly at ISS or tom cat..or appache..) and no exe is installed on the client machine..
happy reading..
thanks rahul,
so yahoo messenger is nothing but thick client.i mean client needs to do everything here and is not dependent on any server.is it so.
so thats why its also desktop application.
but when v type some msg and press ok.first it goes to server or buffer. clarify me here. then from buffer or server that msg goes to respective user.
am i write or wrong.
i understood the concept u explained but still i need some more clarification regarding this example.
i hope am not creating mess.
Iam not able to understand what is this APACHE AND TOMCAT SERVER is all about..are they different ?
Some say they are not and they are called as webapplication servers.By the way do application server and web server reside on the same machine or in different machines.How they are configured.
How a application server contacts webserver or vice versa..again are they configured on differnet machines .I am totally confused please help me understand this.Respond me to this e mail with your answers norman_g40@yahoo.com
would any one tell me what is the difference between the designation software tester and test engineer.
Hi norman,
Basically servers are to two types :
1. Web servers ( Apache, IIS etc..)
2. Applications servers ( Tomcat, weblogic..etc)
1: A webserver is a computer that is running special software allowing people to connect to it from their browser.
2.An application server is a software engine that delivers applications to client computers .
HI viji,
software tester and test engineer both are same.
Hi All,
Hope this helps…
Q: What is the difference between client-server testing and web based testing and what are things that we need to test?
Ans: Projects are broadly divided into two types of:
2 tier applications
3 tier applications
CLIENT / SERVER TESTING
[a] This type of testing usually done for 2 tier applications (usually developed for LAN)
Here we will be having front-end and backend.
The application launched on front-end will be having forms and reports which will be monitoring and manipulating data
Eg : applications developed in VB, VC++, Core Java, C, C++, D2K, PowerBuilder etc.,
The backend for these applications would be MS Access, SQL Server, oracle, sybase, mysql, quadbase
The tests performed on these type of applications would be
- user interface testing
- manual support testing
- Functionality testing
- compatability testing & configuration testing
- intersystems testing
WEB TESTING
[b] This is done for 3 tier applications (developed for Internet / intranet / xtranet)
Here we will be having Browser, web server and DB server.
The applications accessible in browser would be developed in HTML, DHTML, XML, JavaScript etc.,
(we can monitor thru these applications)
Applications for the web server would be developed in Adv Java, ASP, JSP, VBScript, JavaScript, Perl, Cold Fusion, PHP etc.,
(all the manipulations are done on the web server with the help of these programs developed)
The DBserver would be having oracle, sql server, sybase, mysql etc.,
(all data is stored in the database available on the DB server)
The tests performed on these type of applications would be
- user interface testing
- Functionality testing
- security testing
- browser compatability testing
- load / stress testing
- interoperability testing/intersystems testing
- storage and data volume testing
A web-application is a three tier application.
This has a browser (monitors data) [monitoring is done using html, dhtml, xml, javascript]-> webserver (manipulates data) [ manipulations are done using programming languages or scripts like adv java, asp, jsp, vbscript, javascript, perl, coldfusion, php] -> database server (stores data) [data storage and retrieval is done using databases like oracle, sql server, sybase, mysql] .
The types of tests which can be applied on this type of applications are:
1. User interface testing for validation & user friendliness
2. Functionality testing to validate behaviors, i/p, error handling, o/p, manipulations, services levels, order of functionality, links, content of web page & backend coverage’s
3. Security testing
4. Browser compatability
5. Load / stress testing
6. Interoperability testing
7. Storage & data volume testing
a client-server application is a two tier application.
This has forms & reporting at front-end (monitoring & manipulations are done) [ using vb, vc++, core java, c, c++, d2k, power builder etc.,] -> database server at the backend [data storage & retrieval) [ using ms access, sql server, oracle, sybase, mysql, quadbase etc.,]
the tests performed on these applications would be
1. User interface testing
2. Manual support testing
3. Functionality testing
4. Compatability testing
5. Intersystems testing
Desktop:
01. Application runs in single memory (Front end and Back end in one place)
02. Single user only
Client/Server:
01. Application runs in two or more machines
02. Application is a menu-driven
03. Connected mode (connection exists always until logout)
04. Limited number of users
05. Less number of network issues when compared to web app.
Web:
01. Application runs in two or more machines
02. URL-driven
03. Disconnected mode (state less)
04. Unlimited number of users
05. Many issues like hardware compatibility, browser compatibility, version compatibility, security issues, performance issues, etc
see friend when we consider the security testing, both application should well secured to internal and external threat.
As per difference in both the applications come where, how to access the resources. In client server once connection is made it will be in state on connected, whereas in case of web testing http protocol is stateless, then there comes logic of cookies, which is not in client server.
More for client server users are well known, whereas for web any user can login and access the content, he/she will use it as per his intentions.
so, there are always issuses of security and compatibility for web application.
Regards,
Vijay
thanks….
any one tell me where server handling and administration will told us properly in vizag
Hi Shilpa,
I have mentioned Types of Testing generally use in Practical as below:
1.smoke and Sanity Testing.
2.functionality Testing
3.Compatibility Testing
4.GUI Testing
5.Regression Testing
6.Re-Testing
7.UAT
These are the basic Testing but so many testings is there but these are depending upon the application functionalities.
Thanks,
Suresh

Hi
Although I from travel field and try to stubborn in this field but this article and discussion helped me very much to understand the difference.
I have an image but illogical but I m happy to get it.
Thanks to all
Thnx buddy.
Good Collection man.
Keep updating us.
I came to know much thing by your blog.
Hi,
This is really too good.
Hi
Can anyone tell me wht is the diff bet smoke testing and sanity testing?
Example of Bugsheet,
Thanks Vijay for the valuable infromation
This blog is really good……Even complex terms are explained in a simpler way.
Anyways, I have a question on my mind.
What’s the difference between Test Engineer and Quality Engineer?
Are both the terms one and the same?
Hello Friends,
Can anyone let me know which tool i can use for Load testing while there is Desktop + Web based application?
