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.

Answer / devki

it is a type of integration testing in which s/w elements,
h/w elements, or both are combined all at once, rather
than in stages

Answer / vijay bhaskar

big bang approach is nothing but system approach.after
completion of all the modules and integrate it, testing is
done.

Answer / anuradha

all the modules are integrated first at once and then
testing prformed . Disadvantage of this is we cannot point
out the origin of the bug , i mean to say if there is any
bug , then it is difficult to developer to find out which
part of application is not working or whether their is any
mistake while doing the integration of modules

Answer / raju

code for all the project modules is written first and no
testing is done till code for every module is written and
when code for all the modules is ready testing is done by
integrating all the modules at once.

here the problem is its difficult to find where the bug is
from whether it is from module level or interface level.

this approach is suitable for small sequential projects but
not for projects having many modules.

Answer / raju

in the answer #7 it was mentioned as no testing is done but
the unit tested modules are integrated to test finally

Answer / divya chavda

BIg bang model is one kind of SDLc life cycle model it is
h/w and s/f integration testing.it have little planig,and
sheduling process,and all form are combined in big bang
integration approach.

Answer / geetha j k

In Non-incremental method, we integrate all the modules at a time. This method is basically a "big-bang" approach. This method, while common, is not recommended because it makes it almost impossible to determine the cause of any errors or problems.

Answer / subhajit

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.
