Black Box Testing:- Black Box Testing is a System Testing.
Here we check the complete functionality of the application.
Here the tester does not examine the programming code and
does not need the knowledge of any coding standards. Here he
enters an input and check whether we are able to get the
exact output irrespective of what is happening in the code.
Here we have functional testing and non-functional testing.
Again both are of different concepts.
White Box Testing:- White Box Testing is non-system
testing. Here the tester should have the knowledge of coding
standards. Here we should review the entire coding part like
we should go through the statement coverage testing, branch
testing and loop testing, mean to say that we have to check
the complete coding standards and mainly here we do Mutation
testing (like we make some changes to the existing code and
run the code and check whether we are able to get any error
or not). This again has lot of subject to learn, can’t be
described but you have to refer to the books to get the
complete knowledge on it. For more clarification if you have
the book called “Art of Software testing” it will make u
clear on these topics.
