1. Big Bang approach: Suppose we need to test integration between two modules. One module is already developed but the other is not yet developed. So we need to wait for the second module to ready and then start testing.

Disadvantage is: It is time consuming as it increases execution time and makes difficult to analyze the issue.

2. Incremental approach: Suppose one module is already developed but the other is not yet developed. In this case developers create dummy module (Stub or Driver) for module communications.

Note: Types of Incremental approach-
a. Up down approach (Stub is created)
b. Bottom Up approach (Driver is created).
