API Testing

Definitions

1. The practice of verifying that an API behaves correctly across success paths, edge cases, failures, authentication scenarios, and contract expectations. API testing often includes schema checks, integration tests, load tests, and negative cases around invalid input or rate limiting.

   In plain English: Testing an API to make sure it behaves correctly under different conditions.

   Example: "Their API testing caught a regression where the new auth middleware broke file uploads only on chunked requests."
