TestNG Data-Driven Testing

Master TestNG data-driven testing including DataProviders, Factory patterns, and parameterization for comprehensive test coverage. This skill covers techniques for testing with multiple data sets efficiently.

Overview

Data-driven testing separates test logic from test data, enabling a single test method to run against multiple inputs. TestNG provides powerful features for data-driven testing through DataProviders, Factory methods, and XML parameterization.

DataProvider Basics
