🧠Manual Testing Knowledge You Already Have
One of the biggest advantages for manual testers is that many API testing concepts are already familiar.
For example:
| Manual Testing Concept | API Testing Application |
|---|---|
| Test Scenario | API behavior to validate |
| Test Case | API request + expected response |
| Positive Testing | Valid request |
| Negative Testing | Invalid request |
| Boundary Testing | Minimum/maximum values |
| Validation | Response verification |
| Regression Testing | Re-running API tests |
| Defect Reporting | Reporting API failures |
So you are not starting from zero.
You are simply applying your existing testing knowledge to a different layer of the application.
