Question

When will the interface errors get detected in big bang integration appraoch?

Answer 1

The correct answer is - At a later stage.

Big Bang Integration Testing is a type of integration testing strategy in which all the units are linked at once that results in a whole system. When this strategy is adopted, it becomes difficult to isolate errors found as no attention is paid to verify the interfaces across the individual units.

The errors and defects that are present in interfaces of the components will be identified at a later stage when the components are integrated in a single shot. So, there are chances that these defects will pop up in the production time.
