Data-driven testing is a robust testing methodology that focuses on testing the functionality of an application using multiple sets of data. Instead of hardcoding input values and expected results, this approach separates test logic from the test data, enhancing reusability and maintainability. Selenium, being a popular automation tool, supports data-driven testing seamlessly when integrated with testing frameworks like TestNG or JUnit. In this blog, we’ll delve into the concept of data-driven testing, explore its benefits, and demonstrate how to implement it using Selenium with detailed coding examples. What is Data-Driven Testing? Data-driven testing involves executing test scripts multiple times with different sets of input data. The test data is typically stored in external sources such as: Excel files CSV files Databases JSON or XML files This approach is particularly useful for validating applications where the same functionality needs to be tested with ...

TestNG is a popular testing framework for Java applications that enables developers to write automated tests for their code. It provides a rich set of features and annotations that help testers create efficient and comprehensive test suites.  If you are preparing for a TestNG interview, you may be asked a wide range of questions related to the framework. In this blog post, we will cover some of the most commonly asked TestNG interview questions along with their answers and coding examples. What is TestNG and what are its advantages? Answer: TestNG is a testing framework for Java that is designed to cover all categories of tests: unit, functional, end-to-end, integration, and more. TestNG offers several advantages over other testing frameworks, including: Flexible test configuration: TestNG allows testers to configure tests using XML files or Java code. This flexibility makes it easier to customize tests and run them in different environments.
