Cucumber-JVM: Cucumber's @After hook is executed twice

Question

I'm implementing Cucumber Testng for learning purposes. I've realized that the @After hook method is executed twice. I can confirm it with debugging set and a test report output. I only run 1 feature file and my test report shows two entries with identical class names.

Does anyone know why?

Code:

@After
    public void tearDown(Scenario scen) throws IOException {
        ExtentTest logger = reportMgr.getLogger();
        String feature = getClass().getName() + " Feature";    //+ "." + Thread.currentThread().getStackTrace()[1].getMethodName().toString();

        logger = reportMgr.getExtent().createTest(feature);

        String screenShot = CaptureScreenshot.captureScreen(WebDriverManager.driver, CaptureScreenshot.generateFileName(feature));
        if (!scen.isFailed()) {
            logger.pass("Pass");
            logger.addScreenCaptureFromPath(screenShot);
        } else {
            logger.fail("Fail");
            logger.addScreenCaptureFromPath(screenShot);
        }
    }

Feature File:

@Login_Valid Feature: Login to Volare Collector Description:  As a user, I want login to Volare Collector 

  Scenario: Valid Login
    Given Volare Collector Home Page opens in browser
    When I login to Volare Collector with Username and Password
    Then Page navigate to Volare Collector Home Page

There is warning in the feature file called Multiple Definitions "Volare Collector Home Page opens in browser".

Please download my source code from this link.

Add the feature file also. Are there two scenarios in this feature file? — Grasshopper, Apr 13 '18 at 08:10
Only one scenario in the feature file but there is warning about multiple definitions for "Volare Collector Home Page opens in browser". — nicholas, Apr 13 '18 at 09:44
You should only have an unique definition for a step. Strange you are not getting an exception also. — Grasshopper, Apr 13 '18 at 09:59
Are you sure that you only have one \@After hook defined? Each \@After hook is executed so if you have two, each one gets executed. Post all of your code. — MikeJRamsey56, Apr 13 '18 at 20:36

testng.xml calls the TestRunner class. In the cucumberoptions there is no tags option, therefore no filtering based on tags. Thus it will pick up all the feature files in the folder given in features option - "src/Features" ie. Login.feature and Logout.feature.

Each of the feature files has one scenario each. Therefore there are 2 scenarios in total and thus 2 tests will be run. This explains why you see 2 tests in the report.

When each scenario runs, they will run any present Before and After hooks. So for 2 scenarios, hooks will be run twice.

Also hooks are global in nature ie, as long they are present in any classes in the option defined in glue(glue = {"Step_Definitions"}) they will be picked up. In your case you have two Before hooks in Login and Logout classes, you may want to look at fixing that. Use a Before hook and pass it a tag filter in the value option.

In the single After hook defined in the Login class this piece of code

String feature = getClass().getName();          
logger = reportMgr.getExtent().createTest(feature);

This means that name of the test will always be the full class name ie. Step_Definitions.Login. Therefore it shows up as 2 tests with same names although they are different.

I assume that you are using TestNG 6.8 or higher

Use the following Test class template and check if you have the issue

import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

class PlaygroundTest {

  @BeforeClass
  public void setUp(){

  }

  @AfterClass
  public void tearDown() {

  }

  @Test
  public void test(){

  }
}
