Data Driven API Testing in Java with Rest-Assured and TestNG: Part 1

Data-driven testing , also known as parameterized testing , is a technique that uses a data table to drive test execution by defining inputs, expected outputs, and test environment settings. It separates test data from test logic. Rather than creating multiple test cases for different input values, a single test case is executed repeatedly using different data sets. The TestNG framework provides the @DataProvider annotation, which supplies data sets to tests. There are multiple ways to perform data-driven API testing using TestNG’s @DataProvider . In this article, we will learn how to pass test data using an  Object array .
