    Re: Examples of black and white box testing

    White-Box-Testing: this is done by the developer himself.
    Eg. Imagine a program function that that contains the programming constructs like conditional blocks, iterative blocks etc. A developer has to test if these programming constructs are placed correctly and carries out the required action or not. This kind of testing at the detailed level is called white-box-testing.

    Black-Box-Testing: this is done by a test engineer.
    Eg. Imagine that the above program function is implemented. The tester has to check if this program function works fine in coordination with other parts of the s/w and works correctly on the input arguments and gives correct output.

    Lack of WILL POWER has caused more failure than
    lack of INTELLIGENCE or ABILITY.

    Sarnam, White box and black box both uncover different types of errors , so, need not to explain it.

    The question may be modified in a way give example of bugs which are same when uncovered by both type of testing.
