TestNG - Parameter Test (XML and @DataProvider) In this tutorial, we will show you how to pass parameters into a @Test method, via XML @Parameters or @DataProvider. We can use itfor parameter testing. Causes the test method to be invoked once for each element of the iterator. This is particularly useful when several test methods use the same @DataProvider and you want it to return different values depending on which test method it is supplying data for. Passing multiple parameters is just similar to the single parameters, but we will be providing multiple values in a single parameter. DataProviders are separate methods used in test functions, which means that this annotation is not used on test functions like the testNG parameters. What is the use of DataProvider in TestNG? Before we proceed, lets understand the benefit of the data-driven/parametric testing. Note: TestNG comes up with DataProvider to automate the process of providing test-cases for execution. The preceding class file contains a single test method that takes one parameter as input. Rerun Failed test in Selenium Automation Framework. Similar to TestNG Parameters, DataProviders are a means to pass data to test scripts in TestNG. It is inheriting the dataproviders. As an upgrade to this situation, we can pass the same dataprovider to various test methods also. Go ahead and try out some login functionality with different sets of data all passed into a single DataProvider method on your own and see how efficient the execution becomes. How to execute parallel testing using methods & classes & suites in TestNG with Selenium WebDriver. TestNG provide two option that you can choose to pass test data to your test method. Since I told this method that my dataprovider class is DP.java, I will create another file DP.java and write my dataprovider code there. NOTE: The "parallel" parameter here will actually fork a separate TestNG process, without adhering to the "thread-count" parameter in your testng.xml file.For example, if thread-count specified 10, and each of your test cases has 10 rows of DataProvider input, you will actually run 100 tests in parallel!
