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
以下是我使用的依赖项：

    <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cumber测试时，它只打印Before Scenario和After Scenario与此同时，我希望看到，This is before step和This is after step 在之前和在每个步骤之后

那么，为什么@AfterStep和@BeforeStep不起作用呢

• 你应该提供一个小例子，其他人可以用它来重现你的问题

看看这个小片段，它正在发挥作用

假设以下结构

pom.xml
src/test/java/TestRunner.java
src/test/java/stepdefs/StepDefinitions.java
src/test/java/stepdefs/Hooks.java
src/test/resource/features/demo.feature

pom。xml

...
<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.target>1.8</maven.compiler.target>
    <version.cucumber>4.2.0</version.cucumber>
</properties>

<dependencies>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-java</artifactId>
        <version>${version.cucumber}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-junit</artifactId>
        <version>${version.cucumber}</version>
        <scope>test</scope>
    </dependency>
</dependencies>

TestRunner。java

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

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

步骤定义。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()");
    }
}

钩子。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");
    }
}

演示。功能

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

产生以下输出
