    In Black-box testing
    It attempts to find errors in following categories :
    a) Incorrect or missing functions

    b) Interface errors

    c) Errors in data structures or external database access

    d) Performance errors

    e) Initialization and termination errors.

    Whereas, white box testing attempts errors in following cases

    a) Internal logic of your program.

    b) Status of program.
