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

[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

[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

01. Application runs in single memory (Front end and Back end in one place)
02. Single user only

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.

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.

#40 shruti

Hi all,

Can anybdy tell me how much importance is given to usability testing while testing websites.Moreover,which techniques r actually used.

#41 sate


In reply to your question usability is the one of most important part that we consider while testing any web application/site, there are numerous number of user can use a website/application so that we need to check the usability of the website for numerous number of users. Usability make sure that a website/application should be very easy to use for end user.

Techniques front, i would recommend that testing guy should test the website/application with end-user point of view, how easily a end-user can get the desire information within less time that really important.

i hope this helps….
please amend/add if anything missed…


#42 shruti

Thanx Sate,
CAn u pls tell me ur country n different methods used while testing usability.Actually,for research i need to know region wise.Like through different articles I’ve cm to know High tech labs are used to record the user’s expressions n all but as cost incurred is high so how many companies r using n which methods usually u ppl r using.

Thanx for ur reply.It is really a gr8 help.as i was wondering whether it is tested or not.
