Question

我正在尝试使用Junit黄瓜为我的测试运行生成Extent报告，但我收到错误

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

我的错误跟踪如下 - ：

            Reporter.setSystemInfo("os", "windows OSX");
            Reporter.setTestRunnerOutput("Sample test runner output message");
        }

    /* @BeforeClass

         extentProperties.setProjectName("MyProject");

Answer 1

经过几天的寻找，我也遇到了这个问题的解决方案，我找到了原因（至少对我有用）。显然，pluggin com.cucumber.listener.ExtentCucumberFormatter或 com.vimalselvam.cucumber.listener.ExtentCucumberFormatter（适用于cucumber-extentreports版本3.1.1+）仅适用于info.cukes程序包的cucumber。

<! - https://mvnrepository.com/artifact/info.cukes/cucumber-java ->
<dependency>
<groupId>info.cukes</ groupId>
<artifactId>cucumber-java</artifactId>    
<version>1.2.5</ version>
</dependency>

要在最新的黄瓜版本（2.X.X及更高版本的io.cucumber软件包）中使用ExtentReports，您需要添加Cucumber-adapter插件。

对于每个X版本的黄瓜，都有一个适配器，例如对于4.X.X版本的黄瓜，需要extentreports-cucumber4-adapter依赖。

<dependency>
<groupId>com.aventstack</groupId>
<artifactId>extentreports-cucumber4-adapter</artifactId>
<version>1.0.7</version>
</dependency>

在Runner类中，您应该替换插件：

“ com.cucumber.listener.ExtentCucumberFormatter：”

作者

“ com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter：”

有关将黄瓜4与范围报告一起使用的示例，请遵循我发现的GitHub链接：

https://github.com/foursyth/extentreports-cucumber4-example

对于2.X.X和3.X.X版本，遵循与4.X.X相同的原则

所有版本的ExtentReport设置规范链接：

http://extentreports.com/documentation/

希望这会有所帮助。

Answer 2

建议是将您的黄瓜v升级到4.xx 。这样做不仅可以解决您的错误，还可以在并行执行期间生成合并的报告。无需手动创建跑步者。

在黄瓜中实现范围报告有两种方法：

1。将Cucumber-JVM 4适配器用于Extent Framework（extentreports-cucumber4-adapter）-美观，您不需要在任何位置编写任何代码来生成报告，除非从下面的运行程序中设置适配器。

在POM.XML下添加适配器依赖项

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

将com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter插件添加到运行器中。

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

报告输出目录-../项目目录/ test-output / HtmlReport

2。在POM.XML下添加aventstack依赖项

<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。

获取错误“cucumber.runtime.CucumberException：无法加载插件类：com.cucumber.listener.ExtentCucumberFormatter。”
