java - Cucumber-Java - Hook 类 - 退出驱动程序方法不起作用

Question

我是 Cucumber 的新手，我正在尝试实现一个 Hook 类...长话短说: driver.quit();方法无效。

这是我的钩子(Hook)类:

import cl.xxx.util.init.Initializer;
import cucumber.api.Scenario;
import cucumber.api.java.After;
import cucumber.api.java.Before;
import org.openqa.selenium.WebDriver;


public class ServiceHooks {

    protected WebDriver driver;

    @Before
    public void initializeTest()throws Exception{
        // Code to setup initial configurations
        Initializer.getInstance().init();
    }

    @After
    public void embedScreenshot(Scenario scenario) {
        if (scenario.isFailed()) {
            try {
                System.out.println("Test finished with error");
                 driver.quit();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
}

当场景步骤中出现问题时，控制台会显示消息“测试已完成，但有错误”，但不会关闭驱动程序。

如果有人可以帮助我，请。

提前致谢。

我不知道它是否有用，但这是我的 TestRunner:

假设以下文件结构

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

并使用您的pom.xml和TestRunner以及以下内容

演示.功能

Feature: Test Before and After hook

  Scenario: Test hooks for a non failing scenario
    Given a successfull step

  Scenario: Test hooks for a failing scenario
    Given a not successfull step

StepDefinitions.java

package stepdefs;
import org.testng.Assert;
import cucumber.api.DataTable;
import cucumber.api.PendingException;
import cucumber.api.java.After;
import cucumber.api.java.en.And;
import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;
import cucumber.api.java.en.When;

public class StepDefinitions {
    @Given("^a successfull step$")
    public void aSuccessfullStep() throws Throwable {
        System.out.println("a successfull step");
    }

    @Given("^a not successfull step$")
    public void aNotSuccessfullStep() throws Throwable {
        System.out.println("a not successfull step");
        Assert.fail();
    }
}

ServiceHooks.java——仅添加了一些日志记录

package stepdefs;

import cucumber.api.Scenario;
import cucumber.api.java.After;
import cucumber.api.java.Before;

public class ServiceHooks {

//    protected WebDriver driver;

    @Before
    public void initializeTest()throws Exception{
//        Initializer.getInstance().init();
        System.out.println("Before hook");
    }

    @After
    public void embedScreenshot(Scenario scenario) {
        System.out.println("After hook");
        if (scenario.isFailed()) {
//            try {
//                System.out.println("Test finished with error");
//                driver.quit();
//            } catch (Exception e) {
//                e.printStackTrace();
//            }
            System.out.println("action for failed scenario ...");
        }
    }
}

使用 mvn test 运行测试会产生以下输出

Results :

对于这两种执行的场景，您都可以找到字符串 After hook，而对于失败的场景，您还可以找到失败场景的操作 ...。

这意味着问题很可能出在您的另一段代码中。
