Parameterization In TestNG helps us pass data through the code and prevent hard-coding. However, TestNG parameters enable us to pass the values only once per execution cycle. To overcome this, we can use DataProvider in TestNG that allows us to pass multiple parameters to a single test in a single execution. Using DataProviders, we can easily pass multiple values to a test in just one execution cycle.
What is a DataProvider in TestNG?
Similar to TestNG Parameters, DataProviders are a means to pass data to test scripts in TestNG. Using DataProvider in TestNG, we can easily inject multiple values into the same test case. It comes inbuilt in TestNG and is popularly used in data-driven frameworks.
