Provide Dynamic Test Data To TestNG Tests At Runtime Using @DataProvider

TestNG DataProvider Tutorial | Dynamic Test Data in TestNG with CSV + Selenium Example In this step-by-step tutorial, you will learn how to provide dynamic test data to TestNG tests at runtime using @DataProvider. I've covered both runtime data generation and reading test data from CSV/Excel files, along with a real Selenium login test example. What you’ll learn in this TestNG tutorial: ✅ How TestNG @DataProvider works with examples ✅ Providing dynamic test data at runtime (Java logic) ✅ Using CSV file as DataProvider in TestNG ✅ Running tests multiple times automatically with different inputs ✅ Selenium + TestNG integration for login automation ✅ Complete Maven project setup with pom.xml and testng.xml 📂 Project Structure Covered: TestDataProvider.java → Generate data dynamically / read from CSV LoginTest.java → Test class using @DataProvider testdata.csv → Sample external data file pom.xml → Maven dependencies (TestNG + Selenium) testng.xml → TestNG suite configuration Run Commands for Maven TestNG Project: mvn clean install mvn test Demo site used for Selenium login automation: https://the-internet.herokuapp.com/login By the end of this video, you will be able to: 1. Write data-driven tests in TestNG 2. Use dynamic data with @DataProvider 3. Read data from CSV or Excel in TestNG 4. Automate real login tests with Selenium + TestNG If you found this video helpful: 👍 Like this video 🔔 Subscribe to the channel 💬 Drop your questions in the comments — I reply to everyone! #TestNG #DataProvider #Selenium #AutomationTesting #JavaForTesters #SDET #TestNGTutorial #DataDrivenTesting #CSVDataProvider #MavenTestNG #SeleniumFramework
