API Testing

Overview

API Testing 9 Types

Smoke Testing

This is done after API development is complete. Simply validate if the APIs are working and nothing breaks.

Functional Testing

This creates a test plan based on the functional requirements and compares the results with the expected results.

Integration Testing

This test combines several API calls to perform end-to-end tests. The intra-service communications and data transmissions are tested.

Regression Testing

This test ensures that bug fixes or new features shouldn’t break the existing behaviors of APIs.

Load Testing

This tests applications’ performance by simulating different loads. Then we can calculate the capacity of the application.

Stress Testing

We deliberately create high loads to the APIs and test if the APIs are able to function normally.

Security Testing

This tests the APIs against all possible external threats.

UI Testing

This tests the UI interactions with the APIs to make sure the data can be displayed properly.

Fuzz Testing

This injects invalid or unexpected input data into the API and tries to crash the API. In this way, it identifies the API vulnerabilities.
