Maven Tests Does Not Run Cucumber Scenarios with Spring Boot 2.2 and JUnit 5

Question

I am trying JUnit 5 and Cucumber at Spring Boot 2.2.6 and will need both BDD scenarios and unit tests at my application. I have created a dummy ping controller corresponding feature file which are OK.

Cucumber tests are not called when I run mvn clean test. Only JUnit test is called. However, I can run Cucumber scenarios from Intellij GUI when click on the Run Test button for CucumberTest.java.

Here are my classes:

DummyApplicationTests.java:

package com.a.dummy;

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.junit4.SpringRunner;

@SpringBootTest
@ActiveProfiles("test")
public class DummyApplicationTests {

    @Test
    public void contextLoads() {
    }

}

CucumberTest.java:

package com.a.dummy.bdd;

import io.cucumber.junit.Cucumber;
import io.cucumber.junit.CucumberOptions;
import org.junit.runner.RunWith;

@RunWith(Cucumber.class)
@CucumberOptions(features = "src/test/resources/features")
public class CucumberTest {
}

CucumberSpringContextConfiguration.java:

package com.a.dummy.bdd;

import com.a.dummy.DummyApplication;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.ContextConfiguration;

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ActiveProfiles("test")
@ContextConfiguration(classes = DummyApplication.class)
public abstract class CucumberSpringContextConfiguration {

}

PingTest.java:

package com.a.dummy.bdd.steps;

import com.a.dummy.bdd.CucumberSpringContextConfiguration;
import io.cucumber.java.en.And;
import io.cucumber.java.en.Then;
import io.cucumber.java.en.When;

public class PingTest extends CucumberSpringContextConfiguration {

    @When("^the client calls /ping")
    public void the_client_issues_GET_ping() {
        ...
    }

    @Then("^the client receives status code of (\\d+)$")
    public void the_client_receives_status_code_of(int statusCode) {
        ...
    }

    @And("^the client receives ping response")
    public void the_client_receives_ping_response_body() {
       ...
    }
}

What I am missing?

Answer 1

If you just upgraded to Spring 2.4.0 and maven doesn't run you integration tests, it's because:

Cucumber is based on JUnit 4. If you’re using JUnit 5, remember to include junit-vintage-engine dependency, as well. For more information, please refer to JUnit 5 documentation.
Cucumber documentation

From Spring Boot 2.4.0 reference you can fix it as follows:

If you have tests that use JUnit 4, JUnit 5’s vintage engine can be used to run them. To use the vintage engine, add a dependency on junit-vintage-engine, as shown in the following example:

<dependency>
    <groupId>org.junit.vintage</groupId>
    <artifactId>junit-vintage-engine</artifactId>
    <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>org.hamcrest</groupId>
            <artifactId>hamcrest-core</artifactId>
        </exclusion>
    </exclusions>
</dependency>

Answer 2

JUnit 5 support has not yet integrated and I had to include junit-vintage due to RunWith is a Junit 4 annotation.
