Retrieve parameter value from testNG.xml file

Question

I want to print the value \"iPhone5\" from the key parameter name =\"webdriver.deviceName.iPhone\" .

Answer 1

There are basically two ways in which you do this from within a Test Class (A test class is essentially a class that houses one or more @Test/configuration methods)

1. Via the ITestContext object. You can get access to the current method's ITestResult object by calling Reporter.getCurrentTestResult().getTestContext()
2. Using Native injection wherein you have TestNG inject a ITestContext object. For more details on native injection please refer to the TestNG documentation here

Here's a sample that shows both these in action.

import org.testng.ITestContext;
import org.testng.Reporter;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

public class SampleTestClass {

  private static final String KEY = "webdriver.deviceName.iPhone";

  @BeforeClass
  public void beforeClass(ITestContext context) {
    String value = context.getCurrentXmlTest().getParameter(KEY);
    System.err.println("webdriver.deviceName.iPhone = " + value);
  }

  @Test
  public void testMethod() {
    String value = Reporter.getCurrentTestResult().getTestContext().getCurrentXmlTest().getParameter(KEY);
    System.err.println("webdriver.deviceName.iPhone = " + value);
  }
}
