如何使用Maven和小胡瓜并行运行黄瓜jvm测试方案？

Question

我正在尝试基于黄瓜标签在Maven中运行Junit黄瓜功能套件。 我可以让它们按顺序运行，但不能并行运行。 我找到了一个名为Courgette的程序包，该程序包应该可以解决我这个问题。

但是我无法运行测试，我在github上查看了示例maven项目。它与Cucumber.class一起运行良好，但与小胡瓜一起引发了错误。

任何帮助将不胜感激。

我在pom中包含以下内容

<repositories>
        <repository>
            <id>jcenter</id>
            <url>https://jcenter.bintray.com/</url>
        </repository>
</repositories>
<dependency>
    <groupId>io.github.prashant-ramcharan</groupId>
    <artifactId>courgette-jvm</artifactId>
    <version>2.4.4</version>
    <type>jar</type>
</dependency>

我正在这样调用跑步者。

import courgette.api.CourgetteOptions;
import courgette.api.CourgetteRunLevel;
import courgette.api.junit.Courgette;
import cucumber.api.CucumberOptions;
import org.junit.runner.RunWith;

@RunWith(Courgette.class)
@CourgetteOptions(
        threads = 1,
        runLevel = CourgetteRunLevel.FEATURE,
        rerunFailedScenarios = false,
        showTestOutput = true,
        cucumberOptions = @CucumberOptions(features="src/test/resources/Features/Online/Regression/",
        plugin={"html:target/OD.html","json:target/OD.json"
                },tags={"@Max"},
                glue="com.Online"
                ))
 public class ONLINE_Regression_RunnerTest {
}

我收到以下错误。

Answer 1

请注意，从v4.x开始，Cucumber-jvm提供了并行选项。

Answer 2

通过将依赖关系移到pom的顶部，我可以消除冲突。 似乎与测试ng依赖项存在冲突。

Answer 3

有N种方法（如下所述）可以实现并行执行，而最可取的方法之一是使用从V 4.0.0开始的Cucumber（特别是当我们必须仅在多个浏览器上实现并行执行时，而不是在多操作系统）

1. 黄瓜-JVM-并行插件
2. TestNG的
3. 硒网格
4. 搬运工人
5. 西葫芦，JVM

为了实现4.0.0，请使用以下一组黄瓜依赖项以及Maven配置，我们也将实现依赖项注入。
