Unit Testing And Integration Testing
# Unit Testing -
- Unit testing conducts on single program or single module.
- in unit testing small components or program test by the developer.
- Whenever the application is ready and given to the Test engineer, he/she will start checking every component of the module or module of the application independently or one by one, and this process is known as Unit testing or components testing.
- Unit testing is white box testing technique.
* Unit Testing techniques -:
- Basis path testing
- Control structure testing
- Conditional Coverage
- loops coverage
# Integration Testing -
- Integration testing performed between 2 or more modules.
- integration testing focuses on checking data communication between multiple modules.
- integrated testing is white box testing technique.
* Types of integration testing
- 1) incremental integration testing
- 2) Non- Incremental integration testing
(1) incremental integration testing - incrementally adding the modules and testing the data flow between the modules.
- in this 2 Appoches have
i - Top Down incremental integration testing :-
ii- Bottom- up incremental integration testing :-
(2) Non- Incremental integration testing - Adding all the modules in a single shot and test the data flow between modules.
