How to Write Tests in Postman | API Response Validation Step by Step | Part 12

In this video, we’ll learn how to write tests in Postman using JavaScript and validate an API response step by step. We will use the FakeStore API to understand how real-world API responses look and how we can validate them using Postman’s Tests tab. This video focuses on basic but very important API validations, which are commonly used in API automation and real-time projects. 🎯 What you will learn in this video: ✅ What is the Tests tab in Postman ✅ Is testing in Postman considered automation? ✅ Why Postman uses JavaScript for writing tests ✅ How to use Postman test snippets ✅ Understanding pm.test(), pm.response, and assertions 🧪 Validations covered in this video: 🔹 HTTP-level validations Validate HTTP status code (200 OK) 🔹 Response structure validations Validate response is a JSON Validate response is an array Understand square brackets [] as array Understand curly braces {} as objects Validate array contains multiple objects Validate total number of products in response 🔹 Mandatory property validations Validate each product object contains: id title price description category image rating 🔹 Nested object presence Validate rating exists Validate rating contains: rate count We also understand why we use loops (forEach) to validate multiple objects in a single response. #Postman #APITesting #PostmanTesting #AutomationTesting #APIAutomation #PostmanTutorial #JavaScriptTesting #SoftwareTesting #QALearning #FakeStoreAPI
