The difference between Unit testing and Integration testing:
|
Unit testing |
Integration testing |
|
The unit test is used to test a single module of a system for some sort of specific test. |
Integration testing ensures that module or program works together in a set. |
|
It is performed once the programmer builds the program, tests the code, and believes that there is no error in that code. |
It is conducted by the analyst or programmer and they take responsibility for the cause of the error. |
|
The unit test ensures that the program must perform the task or function that was originally defined to it. |
This testing ensures that the link and the interfaces between the programs work properly. |
|
First, the program is developed, the tester verifies that it is error free, and then the unit test is performed. |
The procedure for the integration testing is same as that of unit testing; here also, tests are developed and then according to the tests cases are developed. |
