How to get the name of a test method that was run in a TestNG teardown method?

TestNG supports native dependency injection. It allows to declare additional parameters in methods. At runtime, TestNG automatically fills these parameters with the correct values. Here's a set of native dependencies in TestNG:

• ITestContext
• XmlTest
• Method
• ITestResult

These dependencies help to retrieve the name of Test method. The name of a Test method can be retrieved before or after the execution of the test.

• If the user wants to get the name of a Test method prior to its execution, then @BeforeMethod can be useful to retrieve it.

• On the other hand, if the user wants to know which Test method is just executed, then @AfterMethod can be used. The actual code can be written in either of these methods to retrieve the name of a Test method.

@BeforeMethod and @AfterMethod support all these native dependencies. The full access of these dependencies is given below −

In this article, we will use Method dependency to show how to retrieve the name of a Test method. However, any of these dependencies can be used for @BeforeMethod or @AfterMethod. The only change will be in the import part where the corresponding library should be imported as per the native dependency used.

Suppose the user wants to retrieve the name of a Test method after its execution. In this case, the code will be written inside @AfterMethod to retrieve the name of the Test method. As @AfterMethod executes each time after the @Test method, the name of the Test method will be printed after its execution.

Approach/Algorithm to solve this problem

• Step 1 − Create a TestNG class NewTestngClass and write the @AfterMethod method.

• Step 2 − Write the following code inside @AfterMethod

public void tearDown(Method method) {
   System.out.println("Test name: " + method.getName());
}

Note − Instead of parameter Method, any of remaining three native dependencies can be used. For example, ITestContext or XmlTest or ITestResult.

• Step 3 − Write two different @Test methods in the class NewTestngClass.

• Step 4 − Create the testNG.xml as given below to run the TestNG classes.

• Step 5 − Finally, run the testNG.xml or directly testNG class in IDE or compile and run it using command line.

Example

Use the following code for the common TestNG class, NewTestngClass−

src/ NewTestngClass.java

import org.testng.annotations.AfterMethod;
import org.testng.annotations.Test;
import java.lang.reflect.Method;
public class NewTestngClass {
   @Test
   public void testCase1() {
      System.out.println("in test case 1 of NewTestngClass");
   }
   @Test
   public void testCase2() {
      System.out.println("in test case 2 of NewTestngClass");
   }
   @AfterMethod
   public void tearDown(Method method) {
      System.out.println("Test name: " + method.getName());
   }
}

testng.xml

This is a configuration file that is used to organize and run the TestNG test cases. It is very handy when limited tests are needed to execute rather than the full suite.

<?xml version = "1.0" encoding = "UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name = "Suite1">
   <test name = "test1">
      <classes>
         <class name = "NewTestngClass"/>
      </classes>
   </test>
</suite>

Output

in test case 1 of NewTestngClass
Test name: testCase1
in test case 2 of NewTestngClass
Test name: testCase2
===============================================
Suite1
Total tests run: 2, Passes: 2, Failures: 0, Skips: 0
===============================================
