Java:@AfterStep、@BeforeStep 在 cucumber 中不起作用

Question

在我的 Java 和 maven 项目中，我使用 Cucumber 进行 BDD 测试。
这是我使用的依赖项:

    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-java</artifactId>
        <version>4.2.0</version>
    </dependency>

我的 Hooks 类:

import cucumber.api.java.After;
import cucumber.api.java.Before;
import cucumber.api.java.AfterStep;
import cucumber.api.java.BeforeStep;


public class Hooks  {

    @Before
    public void init() {
        System.out.println( " Before Scenario " );
    }

    @After
    public void cleanUp() {
        System.out.println( " After Scenario " );
    }


    @BeforeStep
    public void beforeStep() {
        System.out.println("======>  This is before step  <======");
        //Do something before executing the step
    }

    @AfterStep
    public void afterStep() {
        System.out.println("======>  This is after step  <======");

    }
}

但是当我运行 Cucumber 测试时，它只打印 Before Scenario 和 After Scenario。 与此同时，我希望看到，这是在步骤之前，这是在步骤之后之前和之后每个步骤。

那么，为什么 @AfterStep 和 @BeforeStep 不起作用？

@RunWith(Cucumber.class)
@CucumberOptions(
        features = {"src/test/resource/features"},
        glue = {"stepdefs"}
         )
public class TestRunner {
}

StepDefinitions.java

package stepdefs;

import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;
import cucumber.api.java.en.When;

public class StepDefinitions {
    @Given("^a successful step$")
    public void aSuccessfulStep() {
        System.out.println("    aSuccessfulStep()");
    }

    @When("doing something")
    public void doingSomething() {
        System.out.println("    doingSomething()");
    }

    @Then("something happen")
    public void somethingHappen() {
        System.out.println("    somethingHappen()");
    }
}

Hooks.java

package stepdefs;

import cucumber.api.java.After;
import cucumber.api.java.AfterStep;
import cucumber.api.java.Before;
import cucumber.api.java.BeforeStep;

public class Hooks {
    @Before
    public void init() {
        System.out.println("@Before scenario");
    }

    @After
    public void cleanUp() {
        System.out.println("@After scenario");
    }

    @BeforeStep
    public void beforeStep() {
        System.out.println("  @BeforeStep");
    }

    @AfterStep
    public void afterStep() {
        System.out.println("  @AfterStep");
    }
}

Feature: Test cucumber reporting plugin

  Scenario: Run a non failing scenario
    Given a successful step
    When doing something
    Then something happen

运行测试

$ mvn clean test
