Selenium Tutorial Tutorial Facebook Twitter LinkedIn Using @DataProvider we can create a data driven framework in which data is passed to the associated test method and multiple iteration of the test runs for the different test data values passed from the @DataProvider method. TestNG comes up with DataProvider to automate providing test-cases for implementation. Step 1: Open the Eclipse. Passing multiple parameters is just similar to the single parameters, but we will be providing multiple values in a single parameter. The data is currently stored in either flat files or in simple Excel spreadsheets. Index report contains the index-like structure of different parts of the report, such as failed tests, test files, passed tests, etc. DataProviders pass the different parameters on a single test in a single execution, whereas parameters pass the parameters just once per execution in TestNG. How do you give parameters in TestNG? Let us create separate classes for the DataProvider method and the test method, as shown below: We can see that all we did was create a DataProvider method in a Class and create a new class for Test Code. To jog your memory, Parameterization In TestNG helps us pass data through the code and prevent hard-coding. In our earlier posts, we learned about using TestNG parameters in our TestNG scripts.

TheDataProviderin TestNG is another way to pass the parameters in the test function, the other one being TestNG parameters. If you want to put your data provider in a different class, it needs to be a static method or a class with a non-arg constructor, and you specify the class where it can be found in thedataProviderClassattribute.
