Top-Down Integration Testing
An approach to integration testing where the component at the top of the component hierarchy is tested first, with lower-level components being simulated by stubs. Tested components are then used to test lower-level components. The process is repeated until the lowest level components have been tested. In this approach, testing is conducted from the main module to the submodule. if the submodule is not developed a temporary program called STUB is used for simulating the submodule. Advantages: * Advantageous if major flaws occur toward the top of the program. * Once the I/O functions are added, the representation…
