For the questions from 3 to 20 answers ahve given by Naresh.
I dont want to make comments on this further.

Here I am givign the answers for 1 and 2.

1)Diff. between Application server and web server?
A Web server serves pages for viewing in a Web browser,
while an application server provides methods that client
applications can call.A Web server exclusively handles HTTP
requests, whereas an application server serves business
logic to application programs through any number of
protocols.

The Web server
A Web server handles the HTTP protocol. When the Web server
receives an HTTP request, it responds with an HTTP
response, such as sending back an HTML page. To process a
request, a Web server may respond with a static HTML page
or image, or delegate the dynamic response generation to
some other program such as CGI scripts, JSPs (JavaServer
Pages), servlets, ASPs (Active Server Pages), server-side
JavaScripts, or some other server-side technology. Whatever
their purpose, such server-side programs generate a
response, most often in HTML, for viewing in a Web
browser.The Web server doesn't provide any functionality
beyond
simply providing an environment in which the server-side
program can execute and pass back the generated responses.
The server-side program usually provides for itself such
functions as transaction processing, database connectivity,
and messaging.While a Web server may not itself support
transactions or database connection pooling, it may employ
various strategies for fault tolerance and scalability such
as load balancing, caching, and clustering.

The application server
An application server exposes business logic to client
applications through various protocols, possibly including
HTTP. While a Web server mainly deals with sending HTML for
display in a Web browser, an application server provides
access to business logic for use by client application
programs. The application program can use this logic just
as it would call a method on an object.
The information traveling back and forth between an
application server and its client is not restricted to
simple display markup. Instead, the information is program
logic. Since the logic takes the form of data and method
calls and not static HTML, the client can employ the
exposed business logic however it wants.the application
server manages its own resources. Such gate-keeping duties
include security, transaction processing, resource pooling,
and messaging. Like a Web server, an application server may
also employ various scalability and fault-tolerance
techniques.Additionally, most application servers also
contain a Web server, meaning you can consider a Web server
a subset of an application server. While application
servers contain
Web server functionality, developers rarely deploy
application servers in that capacity. Instead, when needed,
they often deploy standalone Web servers in tandem with
application servers.

You must test a trouble report where the problem cannot be reproduced. You tried using various test data files and mutations from the data files the customer sent along with the trouble report. The software does not fail the way it did at the customer's site.

Hi, Can anyone suggest a test case writing technique for the below scenario. 1. User draws a lines on the image 2. User selects the lines and right clicks ( Measuremnts like distance between the start and the end point, coordinates of start point and coordinates of end point) 3. User selects one of the measurement Measurement is displayed Just want to highlight, i am looking for a test case writing technique for above scenario.

Our software designers use UML for modeling applications. Based on their use cases, we would like to plan a test strategy. Do you agree with this approach or would this mean more effort for the testers.
