The document discusses the importance and techniques of API testing within software testing, covering types such as unit and functional testing. It outlines guidelines for API testers, challenges they face, and emphasizes the need for a unified testing framework and continuous testing integration. Additionally, it highlights tools and strategies to strengthen API management and testing effectiveness.

1. API Testing
A NICHE CATEGORY IN SOFTWARE TESTING

2. API testing
 Interfaces to the core application logic
 Becomes very important for testing

3. Types of API Testing
 Unit testing
 Functional testing
 Web UI testing
 Security testing
 Load testing
 Runtime error detection

4. API Tester Guidelines
 Prioritize API function calls
 Automate grouping of test categories &
priorities
 Analyze successful and failed outcomes
 Add stress to the testing environment
through load tests
 Check robustness in handling tricky issues
& loads

5. Challenges of
API Testing
 Tester requires detailed knowledge of the
interpretations
 The white-box approach pushes the
tester to be conversant with core logic

6. Making API Testing
Effective

7. Strategize for the Tests
 A unified framework can be put to use
for testing various protocols

8. Keep the Data Dynamic
 Validating results using data from a database,
file, or previous responses

9. Make the API Tests
Intuitive
 API descriptions like Swagger should be
imported to build API tests quickly

10. Automate testing
 Refactoring approaches to be designed to
update tests

11. Adopt a Continuous
Approach with Ease
 Integrate appropriately into continuous
and agile software development

12. Tools for
Continuous Testing
 Graphical API testing tools like
SoapUI NG
 Command-line support for
automated regression testing

13.  SDK and IDE support for
developer-first testing
patterns
Developer First

14. Strengthening the
API strategy
 API management platforms
 API description formats
 API Performance Monitoring
 Front-end functional testing
 Prompt Issue tracking
 SDK generation
 IoT and other protocols
adherence
