Maven/Junit 并行执行 - Cucumber-JVM v4.0.0
Maven/Junit Parallel Execution - Cucumber-JVM v4.0.0
我正在努力获得 Cucumber-JVM v4.0.0 的新并行执行功能与 JUnit/Maven。
如指定的那样 here，如果您在 POM 中相应地配置 <parallel> 和 <threadCount>，并使用依赖注入来共享状态（我使用的是 Pico Continer），那么您的 Cucumber功能应该并行执行。
但是，当我 运行 Maven 时，它仍然一次只执行一个功能。
我在下面包含了完整的 POM - 有人可以帮忙吗？

如果有帮助，下面是我的 运行ner class（com.softwareautomation.world 是 DI class）
package com.evasoftwareautomation.runners;

@RunWith(Cucumber.class)
@CucumberOptions(
plugin = {"pretty", "html:target/cucumber", "junit:target/cucumber.xml"},

glue = {"com.softwareautomation.stepdefs", "com.softwareautomation.world"},
junit ={ "--step-notifications"},
monochrome = true)
public class CucumberTest {
}
请在下面的 Maven 运行ning 中查看失败的堆栈跟踪：

您正在使用 JUnit 4.12。然而，如上所述，堆栈跟踪告诉我们 surefire 正在尝试使用 JUnit 4.8 的集成。您的 surefire 版本于 2012 年发布，而 JUnit 4.12 于 2014 年发布。您是否考虑过更新您的 maven surefire 插件？
我设法通过显式添加测试框架的依赖项使其工作：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.2</version>
<dependencies>
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit47</artifactId>
<version>2.22.2</version>
</dependency>
</dependencies>
<configuration>
<parallel>all</parallel>
<threadCount>4</threadCount>
</configuration>
</plugin>
把它留在这里，因为它可能对其他人有帮助
以我为例
- maven 没有获取 Junit 5 测试
- 黄瓜测试不是运行并行
成功了
- 添加 junit-jupiter 5.5.2
添加 maven-surefire-plugin 2.22.2 并显式添加
surefire-junit47 2.22.2
