Unit Testing: Unit Testing is done to check whether the individual components of a software/ unit/modules of the source code are working properly.

Integration Testing: It is the process of testing the interaction between integrated units or data transfer between a couple of units tested modules. It is divided into Top-Down Approach, Bottom-Up Approach and Sandwich Approach.
