Parent group article by admin: Key aspects of API testing:

Direct interaction:

API tests send requests directly to API endpoints and analyze the responses to ensure they meet expected outcomes.This involves checking status codes, response times, and the structure and content of the data returned.
Focus on business logic:

API testing primarily validates the underlying business rules and data flow within an application, independent of the user interface.
Early defect detection:

By testing APIs early in the development lifecycle, issues can be identified and resolved before they become more complex and costly to fix in later stages.
Automation potential:

API tests are highly automatable, allowing for frequent and efficient execution, which is crucial for continuous integration and continuous delivery (CI/CD) pipelines.
Types of API tests:

This can include functional testing (verifying core functionality), performance testing (measuring response times under load), security testing (identifying vulnerabilities), and integration testing (ensuring seamless communication between APIs and external services).
