Question

我正在尝试使用 Cucumber 和 ExtentReport 在我的 maven 项目中获取报告。我正在使用 java 8。这是我的依赖项：

<dependencies>
    <!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.4.0</version>
    </dependency>

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

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


    <!-- https://mvnrepository.com/artifact/com.vimalselvam/cucumber-extentsreport -->
    <dependency>
        <groupId>com.vimalselvam</groupId>
        <artifactId>cucumber-extentsreport</artifactId>
        <version>3.1.1</version>
    </dependency>


</dependencies>

然后我使用下面的运行ner class 到运行我所有的 *.feature 文件：

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

@RunWith(Cucumber.class)
@CucumberOptions(
        features            = {"src/test/resources/features" }, 
        monochrome          = true,
        plugin              = {"com.vimalselvam.cucumber.listener.ExtentCucumberFormatter:output/report.html"},
        glue                = {"stepDefinitions"}
        )
public class TestRunnerJUnit {


}

但是当我运行测试运行器时，它会抱怨：

更新：

当我添加以下依赖时：

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

我收到这个新错误：

Answer 1

我得到了答案。一切都很好，但我需要向 *.feature 文件中的 Feature 添加一个值。所以，在这里你可以看到 Feature 关键字应该存在，并且 exactly in前面应该是一段文字。如果您将文本写在下一行，您将面临错误。

Feature: Check Welcome-message
  As a user, I should find a welcome-message in my mailbox, and my age in my profile.

Answer 2

Answer 3

尝试替换这个

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

用这个

<dependency>
    <groupId>com.aventstack</groupId>
    <artifactId>extentreports</artifactId>
    <version>3.0.7</version>
</dependency>

组件“cucumber-extentsreport”和“extentreports”是不同的东西。我遇到了同样的问题，并通过使用“extentreports”3.0.7 版和“cucumber-extentsreport”3.1.1 版解决了祝你好运！
