what are the steps involved in writing a test case code example

Example: how to write effective test cases

To write effective test case I have few criteria
1- I put myself into customer shoes by writing
test scenarios by end users perspective
2-I am trying to be specific by using clear statements
to make it understandable by everyone
3-And I am aiming %100 test coverage by
planing my test cases to make sure covers each
component and functionality specified in SRS document
4-And also I actively use test case management tool
jiraxray which helps me not only write text effective 
test cases but also helps me in tracking the progress about them
5-Also I try to keep the description small
simple and informative. Nobody likes to read long stories :)
6-And most importantly I try to do things differently
I try to think exceptionally.
