Smoke Testing
This is done after API development is complete. Simply validate if the API's 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 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.
