API Testing Types:
===============
1. Unit Testing
2. Functional Testing
3. Integration Testing
4. End-To-End Testing
5. Performance Testing
6. Security Testing

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


1. Unit Testing:
============
- Testing single end point is called Unit Testing.

2. Functional Testing:
=================
- Testing specific functionality with in the code-base.
- To test function of API actually works with in the expected parameters.
- Return the expected output for the given input.
- Handles errors when the results are outside of the expected parameters.
- We need to perform positive and negative testing.
- Negative testing checks how an API response to every possible kind of wrong input.
- Positive testing checks the correct functionality of the API when user gives
proper input.
- If positive test cases fails, it is a bad sign. Means, the application can not
perform under ideal conditions.

3. Integration Testing:
==================
- Internal integration -- within the application.
- With third-party services

4. End-To-End Testing:
==================
- It validates the flow of the data and information between different APIs.

5. Performance Testing:
===================
- Need to test how API can handle expected or higher load.
- Validate its functionality and performance by artificially creating or simulating
API calls.

6. #Security Testing:
===============
- It validates whether security requirements are met or not?
- This includes authentication, permission and access control.
