5 types of API testing

(explained in 2 mins or less):

API testing verifies whether APIs work correctly, reliably & securely.

1 Functional testing

↳ Validates whether API returns expected output for a specific request.

↳ Pro: Ensures API behavior matches requirements.

↳ Con: Might miss issues between connected systems.

2 Integration testing

↳ Verifies whether APIs & services communicate correctly together.

↳ Pro: Detects failures between systems or modules.

↳ Con: More complex & slower than isolated tests.

3 Regression testing

↳ Re-runs existing tests after changes to ensure old functionality still works.

↳ Pro: Prevents new updates from breaking existing APIs.

↳ Con: Test suites can become large and time-consuming.

4 Load testing

↳ Measures API performance & stability under expected traffic levels.

↳ Pro: Identifies bottlenecks before production issues occur.

↳ Con: Requires realistic traffic simulations for accuracy.

5 Security testing

↳ Identifies vulnerabilities, authentication flaws & potential attack vectors.

↳ Pro: Helps protect APIs from unauthorized access & exploits.

↳ Con: Cannot guarantee complete protection against all threats.
