You can use it to specify an optional value for a parameter which is not available in the TestNG.XML file. Optional parameters are yet another type of parameter which kind of acts like the “default” attribute of the switch case in programming languages. Try doing public void searchByVisit(@Optional("Abc") String Visit) throws InterruptedException 2.1. TestNG Parameters and DataProvider Annotations – Parameter Testing . In the above example, we have defined two parameters in testng.xml file for two test methods. Your @Parameters do not have a corresponding name in testing.xml. Sorry here is the error: Parameter 'username' is required by Test on method printParametersFromTestNGXML but has not been marked Optional or defined – Sukhvinder Nov 13 '15 at 11:55 D you have another method called printParametersFromTestNGXML( )? Syntax to define Parameter : Syntax to define @Optional annotation Another interesting fact about the TestNG is that it allows passing optional parameters using the @Optional annotation. If defined parameter is not found in your testng.xml file, The test method will receive the default value which is specified inside the @Optional annotation. Through DataProviders. Code Line 30: Using @Parameters annotation to create a set of input data to run our test. HOME. To achieve this we will use @Optional annotation in the test method as an argument. We can use @Optional with method argument to provide a default value, when the parameter is missing from test suite xml file. Parameters in TestNG suite XML file can be defined at suite level or test level. -> We can give only one parameter value for one type of parameter. All Rights Reserved. This feature enables us to execute a single test method multiple times with different parameters. In this tutorial, we're going to explore parameterized tests in depth, so let's get started! Can anyone suggest me how to automate Web services using JAVA/Test NG. Viewed: 156,992 | +22 pv/w. To achieve this we will use @Optional annotation in the test method as an argument. Add test method parameterTest() to your test class. Users may be required to pass the values to the test methods during run time. TestNG Optional Parameters TestNG optional parameters option will provide optional values to a parameter, this value will be used if parameter value is not found or not provided in the xml configuration file.
