TestNG Data Provider - Data Driven Automation Testing TestNg DataProvider is used for Data Driven testing in a Test Automation Framework. Specifying parameters in testng.xml might not be sufficient if you need to pass complex parameters, or parameters that need to be created from Java (complex objects, objects read from a property file or a database, etc…). As mentioned above, DataProvider in TestNG plays an essential role in writing codes for complex projects or objects. Our TestNG tutorial is designed for beginners and professionals. Right click the project name, click ” New —> Others…”, choose “TestNG class” in the popup dialog, click Next. After doing so we can simply pass the Data Provider in TestNG to our test method and our final code would look like below: Now on running this code you will see results like below-. When not working, you will either find her sketching or backpacking. It is always preferred to declare the test case in one class and define TestNG parameters like DataProviders in another class.

Passing multiple parameters is just similar to the single parameters, but we will be providing multiple values in a single parameter. Specifying parameters in testng.xml might not be sufficient if you need to pass complex parameters, or parameters that need to be created from Java (complex objects, objects read from a property file or a database, etc…). This is important because keeping everything in one place might become messy. Before discussing Data-driven framework, let's understand why do we need Framework for Test Automation? Examples of DataProviders. DataProviders are separate methods used in test functions, which means that this annotation is not used on test functions like the testNG parameters. Below we only show you how to add main and sub suite xml in it. TestNG provide two option that you can choose to pass test data to your test method.

DataProviders pass the different parameters on a single test in a single execution, whereas parameters pass the parameters just once per execution in TestNG. It means that even though we ran the file once, the test case method ran twice with different values. The DataProvider annotation has a single attribute called name, which you can select as per your convenience. dataProviderClass: This is the class from where we pass the data to data provider.
