Are you kidding me????  These are your answers?  No wonder 
our offshore testing in India is so abysmal.  You people

What a Joke "J"!!!

A testcase consists of different components -

objective
description
steps
checkpoint
pre-requisites (for executing the test case)
test result

Each of these sections should be clearly mentioned. While
writing test cases it is important to keep in mind that the
test case may even be executed by another person.

The test cases should cover both the equivalence partition
and boundary value conditions.

They should target each part of the application with an eye
for detail. For example, test cases for field validations
should be exhaustive.

Test cases should capture various scenarios that arise while
using the application. This is w.r.t the data flow in the
application. For example, in a web application cases should
cover both a logged in user (cookied user) and visitor
scenarios.
