Using TestNG, is it possible to dynamically change the test name? - junit

Question

Using TestNG, is it possible to dynamically change the test name with a method such as this one below?
#Test(testName = "defaultName", dataProvider="tests")
public void testLogin( int num, String reportName )
{
System.out.println("Starting " + num + ": " + reportName);
changeTestName("Test" + num);
}

Answer 1

No, but your test class can implement org.testng.ITest and override getTestName() to return the name of your test.

Answer 2

For anybody still facing this.
This can be done by implementing the org.testng.ITest class and overriding the getTestName() method just like as #Cedric mentions.
To make the test name dynamic you can use a locally created testName variable In addition. Below is all you need to do
import java.lang.reflect.Method;
import org.testng.ITest;
import org.testng.annotations.Test;
import org.testng.annotations.BeforeMethod;
public class MyTestClass implements ITest {
#Test(dataProvider = "/* yourDataProvider */")
public void myTestMethod() {
//Test method body
}
#BeforeMethod(alwaysRun = true)
public void setTestName(Method method, Object[] row) {
//You have the test data received through dataProvider delivered here in row
String name = resolveTestName(row);
testName.set(name);
}
#Override
public String getTestName() {
return testName.get();
}
private ThreadLocal<String> testName = new ThreadLocal<>();
}
This way you should be able to generate the testName dynamically

I'm getting the error below, about the two parameters of BeforeMethod, what is wrong?
Message:
org.testng.TestNGException:
Method initLog requires 2 parameters but 2 were supplied in the BeforeMethod annotation.
#Parameters({"method", "FinancialKeys"})
#BeforeMethod(alwaysRun = true)
public void initLog(Method method, Object[] FinancialKeys) {...}
