3)what is the difference of approach for Testing Client/server and webappications.(wat is the main difference).
in case of web based testing we have test web browser and pages
but in case of client server testing we test icon of application
that is main difference
Web based Application follows the client Server Architecture.Since in web based, we have a client i.e. Browser itself and the server is at some remote location. There is no such difference between client server and web based but it can be said that applications that are based on the client server architecture are different. Eg. Window based application - in them we need to install the application at each of the client sor user interface server being common for all the clients. but in web based application for user interface there is no need for any installation. The browser is the client itself.
