Integration Testing:
Integration testing (I&T) it called as Integration and Testing and it is important phase of software testing. In application or software integration testing, individual units are combined and tested as group. It is first step and the next step to system testing.

Reliability requirements
The collection of units is executed through their interfaces using black box testing. Error cases and success are being pretended via appropriate parameter and data.
Pretend usage of shared data areas and internal process tested and individual subsystems are executed via their interface.
Test cases are built to test that all components within collection interact correctly. This process is done after unit testing is completed. The whole idea is building blocks.
Types of Integration testing
-
Big bang
-
Top-down
-
Bottom-up
Big Bang
All coded modules are merging to form a complete software system or application and then used for integration testing. The Big Bang method is very effective for saving time in the integration testing process. Test cases and their results are not recorded properly; the entire integration process will be more complicated.
“Big Bang” Integration testing is called Usage Model testing.
Model testing can be used in both software and hardware integration testing.
To run user-like workloads in integrated user-like environments.
Bottom Up
Bottom or low-level modules, procedures or functions are integrated and then tested. After the integration testing of lower level integrated modules, the next level of modules will be formed and can be used for integration testing.
Helpful only when all or most have the modules of the same development level are ready. Determine the levels of software developed and make it easier to report testing progress.
