Here is a 1-paragraph summary of the text: Testing an API should be as rigorous as testing any end-user software, especially if it's a public-facing API intended for public use. To test an API thoroughly, ensure its JSON response payload validates against a provided JSON schema, and that HTTP status codes correctly identify the response or failure. Additionally, test each state change by using only the API to interact with the back-end system as a black-box, and have a testing plan in place to avoid leaving testing to individual developers. RapidAPI for Teams facilitates more robust API testing by providing a uniform interface to all developers/testers on a project, ensuring they have the same interface to test APIs and eliminating the need to instruct team members on where to locate an API or how to use tools like Postman or Curl.
