In big bang Integration testing, individual modules of the
programs are not integrated until every thing is ready. This
approach is seen mostly in inexperienced programmers who
rely on 'Run it and see' approach. In this approach, the
program is integrated without any formal integration
testing, and then run to ensures that all the components are
working properly.

Unfortunately, whilst it may be possible to get away with it
within some simple sequential programs, particularly if
sensible design methods and good Function and Module Tests
have been applied, the use of such an approach large
commercial applications is likely to be much less successful.

The application of this method often simply leads the
programmer to have to re-separate parts of the program to
find the cause of the errors, thereby effectively performing
a full integration test although in a manner which lacks the
controlled approach of the other methods.

Disadvantages

There are many disadvantages of this big bang approach
Defects present at the interfaces of components are
identified at very late stage.
It is very difficult to isolate the defects found, as it
is very difficult to tell whether defect is in component or
interface.
There is high probability of missing some critical
defects which might surfaced in production.
It is very difficult to make sure that all the cases for
integration testing are covered.
