Web Testing & Client server testing

Server process:

 Server programs generally receive requests from client programs, execute database retrieval
and updates, manage data integrity and dispatch responses to client requests. The serverprocess acts as a software engine
 that manages shared resources such as databases, printers, communication links, or high
powered-processors.It is the backend process of the application.

Client process: 
        Client programs usually manage the user-interface portion of theapplication, validate data
entered by the user, dispatch requests toserver programs, and sometimes execute business logic.
The client-based process is the front-end of the application.It is the interaction between the user and the rest of the application
 system.

In client server testing test engineer are conduct the following testings:-

1.Behaviour testing(GUI TESTING)

2.Input domain testing

3.Error Handling testing

4.Backend testing

In Web testing test engineer are condut the following testings:-

1.Behaviour Testing

2.Static web testing

3.Input domain testing

4.Backend testing

5.Error handling testing

5.Frame Level testing

Difference between Application server and Web server:

Application server	Web server
Developers can create, test, and execute application components	It is designed to create and deploy Web site, serving up content more so than applications.
These are typically J2EE-based, running EJBs or other Java components.	It supports JSP,servlets and ASP
Application servers are designed to create true applications with complex business logic,	Web servers are technology designed to create and deploy Web site serving up content more so than applications, serving
Application Server supports HTTP,TCP/IP and many more protocols.	A Web Server understands and supports only HTTP protocol
