Three Essential Approaches for Passing Test Data in Automation Frameworks: JSON, Static DataProvider, and Excel In modern test automation frameworks, passing test data efficiently is crucial for making tests reusable, maintainable, and scalable. In this blog, we’ll cover three powerful ways to pass data in an automation framework using TestNG’s DataProvider feature. These methods offer flexibility to manage test data from various sources like JSON, Excel, or hardcoded data within the test suite. 1. Using DataProvider with JSON (External File) One of the most efficient ways to manage test data is by using JSON files. JSON files can store structured data in key-value pairs, which is easy to parse and pass into test cases. Here’s how to achieve this using TestNG’s DataProvider in combination with a JSON file. Steps: Read JSON file Convert JSON into a POJO Pass the POJO data using DataProvider 1.1 Sample JSON File ( testData.json ) { "users" : [ { "username...
