The Data Driven Framework is an automation testing framework that reads values from data files and stores them in test script variables. It allows testers to combine positive and negative test cases in one test.
Selenium frameworks assist manage test cases by separating the code from the data. Frameworks make code more reusable, legible, and cost-effective to maintain.
Data-driven testing is a key feature of TestNG. DataProviders is a component of data-driven testing that allows you to give different values to a test case in a single run. It implies you can only run a single test case at a time, but you can run a method multiple times with various data values.
An external data source is used to drive test cases and suites using the Data Driven framework. Data sheets such as xls, xlsx, and csv files can be used as the data feed. In Selenium, a Data Driven Framework is a method of separating the "data set" from the actual "test case" (code).
