我是黄瓜可扩展代码的新手，需要帮助。我正在使用Java 8和Maven，并希望生成黄瓜可扩展报告。但是每次我遇到以下错误时：

cucumber.runtime.CucumberException: Couldn't load plugin class: com.cucumber.listener.ExtentCucumberFormatter. It does not implement cucumber.api.Plugin

Pom.xml文件为：

2 个答案:

答案 0 :(得分：0)

POM分析说-

  • 您要保留不同范围的库来创建不建议也不希望的报告。我们将根据需求使用特定的一组集合。
  • 您正在使用黄瓜的相当老的依赖项（ info.cukes v1.2.5 ）
  • 您的pom.xml同时具有直接和传递依赖项

首先让我们对这些库的基本了解来创建范围报告

1。 Vimal Selvam库：以下是必需的maven依赖项和一个示例测试，以演示如何完成配置设置。

Maven依赖 

<dependency>
    <groupId>com.vimalselvam</groupId>
    <artifactId>cucumber-extentsreport</artifactId>
    <version>3.1.1</version>
</dependency>

请注意，必须使用 Java 8 + 并添加 ExtentReport v3.1.1 + 的依赖项。为此，请将以下内容粘贴到pom.xml中： / p> 

<dependency>
    <groupId>com.aventstack</groupId>
    <artifactId>extentreports</artifactId>
    <version>3.1.1</version>
</dependency>

黄瓜跑步者文件 

 @RunWith(Cucumber.class)
    @CucumberOptions(
            features = {"src/test/resources/features"},
            glue = {"com.cucumber.stepdefinitions"},
            plugin = {"com.cucumber.listener.ExtentCucumberFormatter:output/report.html"}
            )
    public class RunCukesTest {
        @AfterClass
        public static void teardown() {
            Reporter.loadXMLConfig(new File("src/test/resources/extent-config.xml"));
            Reporter.setSystemInfo("user", System.getProperty("user.name"));
            Reporter.setSystemInfo("os", "Mac OSX");
            Reporter.setTestRunnerOutput("Sample test runner output message");
        }
    }

以上设置将在输出目录中生成名为report.html的报告。

2。扩展适配器：美丽的是，您无需在任何以这种方式生成报告的地方编写任何代码，除非在下面的运行器中设置适配器。

Maven依赖 

<dependency>
    <groupId>com.aventstack</groupId>
    <artifactId>extentreports-cucumber4-adapter</artifactId>
    <version>1.0.6</version>
</dependency>

将 com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter插件添加到跑步者。

@RunWith(Cucumber.class)
@CucumberOptions(plugin = {"com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter:"})
public class RunCukesTest {
    // ..
}

报告输出目录--.. / Project目录/ test-output / HtmlReport

关键点：：我们不会混合使用直接和传递依赖，特别是它们的版本！这样做可能导致不可预测的结果。我们将要求您使用 Cucumber v> = 4.0.0 ，因为您正在使用Cucumber的相当老的依赖项（ v1.2.5 ）。

首先。您可以添加以下一组黄瓜最小依赖项。

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-junit</artifactId>
    <version>4.2.6</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-picocontainer</artifactId>
    <version>4.2.6</version>
    <scope>test</scope>
</dependency>

第二考虑到不使用扩展适配器的情况，在POM.XML **下添加了以下扩展依赖。

<dependency>
    <groupId>com.vimalselvam</groupId>
    <artifactId>cucumber-extentsreport</artifactId>
    <version>3.1.1</version>
</dependency>

<dependency>
    <groupId>com.aventstack</groupId>
    <artifactId>extentreports</artifactId>
    <version>3.1.5</version>
</dependency>

在此工作流程中，请勿将com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter插件添加到运行器中。

最后一个 Hooks类，我们在其中编写针对每种情况执行的扩展区代码。

公共类挂钩{

private final static Logger log = Logger.getLogger(Hooks.class);
static volatile int x = 0;

@Before
public void setUpScenario(Scenario scenario){
    ExtentTestManager.startTest("Scenario No . " + (x = x + 1) + " : " + scenario.getName());
    ExtentTestManager.getTest().log(Status.INFO, "Scenario No . "+ x + " Started : - " + scenario.getName());
}

@After
public void afterScenario(Scenario scenario){
    String videoFile= Utility.stopAUTTestRecorder();
    try{
        if(scenario.isFailed()){
           ExtentTestManager.addScreenShotsOnFailure();
            //------------------------- Attaching video in the Report -------------------------
            String failedTestVideo = "<a href=\"" + videoFile + "\">Download Failed Test Case Video</a>";
            ExtentTestManager.embedVideoLink(failedTestVideo);
            //scenario.write(failedTestVideo);
        }
        }
        ExtentManager.getReporter().flush();
    }
  }

答案 1 :(得分：0)

尝试在下面的相同版本中使用这2个依赖项 ：

<dependency>
    <groupId>com.vimalselvam</groupId>
    <artifactId>cucumber-extentsreport</artifactId>
    <version>3.0.2</version>
   </dependency>

    <dependency>
    <groupId>com.aventstack</groupId>
    <artifactId>extentreports</artifactId>
    <version>3.1.2</version>
   </dependency>
