    - Top down testing is conducted from main module to sub module. If the sub module is not developed a temporary program, it is called as 'stub', which is used to reproduce the submodule.

    - It takes place from top to bottom that follows the control flow. For example, starting from the GUI or main menu.

    Advantages of Top-down Integration Testing

    - Once the I/O functions are added, representation of test cases is easier.

    - Major decision points are tested early.

    - Stubs can be written with lesser time because when compared to the drivers stubs are simpler to author.
