Queries inside you before start anything - Ask about it

Whenever we start to test the application include your question to overcome many issues. These are the question are rolled out inside my mind....

What is my domain?
Which domain u r going to work?
What is the limits and credits?
Is there anything available already?
In which language my app is going to run?
What are the advantages & disadvantages of language?
What is the requirement of app?
How my app got designed?
What is the customers need?
What to test?
Why to test?
How to Test?
When to start test?
When to finish test?
Which place to test?
What is the major functionality to test?
What's your methodology?
What’s the server name?

Is this true? Do you  really think it is true?
Is this something good about that "third" person?
Is this something that is useful in someway to me?
What if that person about whom we are talking is present right here and listening to you - will you still talk the same way?
