cucumber - Cucumber 5.0.0 和 springboot 多个场景在一个特性文件中

问题描述

我对 springboot 的依赖：

    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-java8</artifactId>
        <version>${cucumber.version}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-java</artifactId>
        <version>${cucumber.version}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-junit</artifactId>
        <version>${cucumber.version}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-spring</artifactId>
        <version>${cucumber.version}</version>
        <scope>test</scope>
    </dependency>



Feature: Bag Functionality

  Scenario: Putting one thing in the bag
    Given the bag is empty
    When I put 1 potato in the bag
    Then the bag should contain only 1 potato

  Scenario: Putting few things in the bag
    Given the bag is empty
    When I put 1 potato in the bag
    And I put 2 cucumber in the bag
    Then the bag should contain 1 potato

当我运行此功能文件时出现异常

它成功运行一个场景并在第二个场景中崩溃。

如果我将黄瓜的版本更改为 4.8.1，这两种情况都可以运行。使用spring boot不可能从黄瓜5中的一个功能文件运行多个场景吗？

解决方案

看起来你遇到了 Cucumber 的错误。Cucumber 在您的步骤定义中找不到上下文配置，因此它回退到GenericApplicationContext无法在场景之间刷新的情况。

尝试将上下文配置添加到您的步骤定义中。例如：

├── pom.xml
└── src
    ├── main
    │   └── java
    │       └── com
    │           └── example
    │               └── Application.java
    └── test
        ├── java
        │   └── com
        │       └── example
        │           ├── RunCucumberTest.java
        │           └── StepDefinitions.java
        └── resources
            └── com
                └── example
                    └── example.feature


package com.example;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {
}

package com.example;

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

@RunWith(Cucumber.class)
@CucumberOptions(plugin = {"pretty"})
public class RunCucumberTest {
}

package com.example;

import io.cucumber.java.en.Given;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.ApplicationContext;
import org.springframework.test.annotation.DirtiesContext;

import static org.junit.Assert.assertNotNull;

@SpringBootTest
public class StepDefinitions {
    @Autowired
    private ApplicationContext applicationContext;

    @Given("an application context")
    public void anApplicationContext() {
        assertNotNull(applicationContext);
    }
}

因为StepDefinitions使用上下文配置 ( @SpringBootTest) 注释，所以黄瓜会将其传递给 Springs TestContextManager。这将创建应用程序上下文并确保场景执行类似于使用SpringRunner/SpringExtension.

您还可以在此处使用其他上下文配置。例如：

package com.example;

import io.cucumber.java.en.Given;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.test.annotation.DirtiesContext;
import org.springframework.test.context.ContextConfiguration;

import static org.junit.Assert.assertNotNull;

@ContextConfiguration("classpath:cucumber.xml")
public class StepDefinitions {
    @Autowired
    private ApplicationContext applicationContext;

    @Given("an application context")
    public void anApplicationContext() {
        assertNotNull(applicationContext);
    }
}
