Big Bang mainly works for the small scale projects. There are numerous disadvantages too that are associated with thus type of testing. If you want to identify faulty localization then it will be really a tough job. Integration testing to be approached only when all modules are ready to be executed in program. Those modules that have high risk should be tested on priority basis.
Incremental approach in the Big Bang: in this one, logical relation is being found for two and more modules. After successful initial testing, other modules are also tested in parallel. This process of testing will go on until all modules do not get properly tested. This is how things to be carried on. Two poplar methods to be carried for the unit testing are bottom up and top down.
What is Stub and Driver?
Stub and driver are two very popular terms when we consider incremental approach of unit testing. There are some other approaches too that are used for the software testing and it all depends on requirement of the project. Check our other blogs for further information about services.
