Test cases for API Testing

API testing is an important step in the development of any application. The need for this is that applications nowadays are connected through APIs and these APIs serve as the glue between applications.

Testing APIs is a critical part of maintaining and improving the quality of your product. It allows you to validate that all the endpoints are functional and in accordance with the documentation. It also gives you a chance to prevent errors, before they even occur.

Testing APIs is becoming a very common requirement. However, it is often too hard to find real and relevant use cases to test them against. In this article, we have collected some API testing tips which can help you deliver better tests faster.

Testing APIs is no longer a low-risk endeavor. In fact, it is becoming essential for any company’s IT department to ensure the security of its applications and web services. With the increasing number of exposed APIs, testing becomes even more important. This article will provide you with some tips and examples on how to test your APIs effectively and efficiently.

• Keys verification. If we have JSON, XML APIs we should verify it’s that all the keys are coming.
• Have a test case to do XML, JSON Schema validation.
• Verify the Parse the Response data
• Verify the JSON Schema validation, Verify the Field Type,Verify the Mandatory Fields
• Valid Response headers & Negative Testcases response
• Verify that how the APIs error codes handled.
• Verify the response HTTP status code.
• Valid Response payload
• Chaining Request verification.
• Verification of APIs with Data parameters.
• End to End CRUD flows
• Database Integrity Test Cases
• File Upload Testcases
