    - Black Box testing 
    - Done without looking at source code or internal structure. 
    - Used to make sure that software handles exceptions or edge cases seamlessly. 
    - Only input and output matters here.

    - Testing for security, 
    - Performance, 
    - Scalability and 
    - Availability

    - Unit Testing: Test an independent module of a code or function. Intended to eliminate error before integration
    - Integration Testing : Tested when multiplle independent modules are combined. Intended to eliminate bugs when modules interact with each other.
