API testing can be performed manually or using automated testing tools. Some common tasks that are performed during API testing. API stands for Application Programming Interface which acts as an intermediate of communication between two applications.

Important type of Testing:

Functional testing: Testing the functionality of the API to ensure it behaves as expected.

Security testing: Testing the security of the API to ensure it is protected against common vulnerabilities.

Performance testing: Testing the performance of the API to ensure it can handle the expected load.

Tools such as Postman, SoapUI, and Runscope can be used to automate and simplify the process of API testing.

Types of API testing:

Unit Testing

Integration Testing

End to End Testing

Performance Testing

Functional testing

Security Testing

Load testing

Penetration testing

Reliability testing

Fuzz testing

Benefits of testing:

Earlier validation of correctness in response and data.

Earlier test maintenance.

Better speed and coverage of testing.

GUI independent testing.

Reduced testing cost.

Disadvantages of API:

There is a lot of conveniences and advantages to APIs, but business leaders should also be aware of the disadvantages. As a single point of entry, an API is a gateway and can become a hacker's primary target. Once the API is compromised, all other applications and systems become vulnerable.
