View the number of passed/failed tests in Java Junit

Question

I want to store the number of passed/failed tests in Java Junit and Cucumber. I have the following code:

public class CucumberE2ETest {

static int passedTest = 0;
static int failedTests = 0;

@Before
public void before() {
    System.out.println("Before tests");
}

@AfterEach
public void afterScenario(Scenario scenario) {
    if (scenario.isFailed()) {
        failedTests++;
    }
    else {
        passedTest++;
    }
}

@After
public static void teardown() {
    System.out.println("Passed: " + passedTest + " Failed: " + failedTests);
}

}

But I receive Passed: 0 Failed: 0, when I run my tests.

You can Implement an EventListener or ConcurrentEventListenerlike below in cucumber and then handle TestCaseFinished events. This example is handling TestCaseFinished and TestStepStarted events. TestCaseFinished event has getResult method . From there you can build up the logic to count pass/fail

    import io.cucumber.plugin.EventListener;
    import io.cucumber.plugin.event.*;
    
    import java.net.URI;
    import java.util.Map;
    import java.util.TreeMap;
    import java.util.UUID;
    
    public class    ReportPlugin implements EventListener {
    
     private final Map<String, UUID> startedSteps = new TreeMap<String, UUID>();
     private final Map<String, Status> finishedCases = new TreeMap<String, Status>();
    
       @Override
        public void setEventPublisher(EventPublisher publisher) {
            
            publisher.registerHandlerFor(TestStepStarted.class, this::handleTestStepStarted);
        publisher.registerHandlerFor(TestCaseFinished.class, this::handleTestCaseFinished);

        }
    
    private void handleTestStepStarted(TestStepStarted event) {
            startedSteps.put(event.getTestStep().toString(), event.getTestStep().getId());
            for (Map.Entry<String, UUID> entry : startedSteps.entrySet()) {
                    String location = entry.getKey();
                    UUID uuid = entry.getValue();
                    System.out.println(location + " ###fromTestStepStarted### " + uuid);
            
             //above prints
            //io.cucumber.core.runner.PickleStepTestStep@5a5c128 ###fromTestStepStarted### 7f964f1c-9442-43fc-97e9-9ec6717eb47f
           // io.cucumber.core.runner.PickleStepTestStep@77b919a3 ###fromTestStepStarted### a5d57753-aecb-40a0-a0cf-76bef7526dd8

                }
        }

      //If you would like to get each test step text you do this

    private void handleTestCaseFinished(TestCaseFinished event) {
        
        
        TestCase testCase = event.getTestCase();
        String scenarioName = testCase.getName();

        TestStep testStep = testCase.getTestSteps().get(0);
        if (testStep instanceof PickleStepTestStep) {
            PickleStepTestStep pickleStepTestStep  = (PickleStepTestStep) testStep;
            String text = pickleStepTestStep.getStep().getText();
            System.out.println("****Pickle Step TestStep*****"+  text);

           //above prints
          //****Pickle Step TestStep*****I open the site ""  
            }

      
        }

   }

To run the above class - put the class with your step defs or your supporting classes and then in junit-platform.properties (for Junit5) mention plugin like this

cucumber.plugin = com.test.support.ReportPlugin

For Junit4 you might have to add plugin to your runner class

When you run your tests you should see everything printed on console
