我正在尝试使用 Junit cucumber 为我的测试运行生成范围报告，但出现错误

"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-：

在寻找同样发生在我身上的这个问题的解决方案很多天之后，我发现了原因（至少对我有用）。显然，插件 com.cucumber.listener.ExtentCucumberFormatter 或 com.vimalselvam.cucumber.listener.ExtentCucumberFormatter （对于 cucumber-extentreports 版本 3.1.1+）仅适用于 info.cukes 包的黄瓜。

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

要将 ExtentReports 与最新的 cucumber 版本（从 2.XX 版本开始的 io.cucumber 包）一起使用，您需要添加 cucumber-adapter 插件。

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

<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：”

经过

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

有关将 cucumber 4 与范围报告一起使用的示例，请访问我找到的 GitHub 链接：

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

对于版本 2.XX 和 3.XX 遵循与 4.XX 相同的原则

所有版本的ExtentReport设置规范链接：

http://extentreports.com/documentation/

希望这可以帮助。

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

在 Cucumber 中有两种实现范围报告的方法：

1. 为 Extent 框架使用 Cucumber-JVM 4 适配器（extentreports-cucumber4-adapter） - 美丽之处在于，除了在下面的运行器中设置适配器之外，您不需要在任何地方编写任何代码来生成报告。

在 POM.XML 下添加适配器依赖

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

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

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

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

2.在POM.XML下添加aventstack依赖

<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。
