我正在努力获取与 JUnit/Maven 一起使用的 Cucumber-JVM v4.0.0 的新并行执行功能。
作为指定here https://github.com/cucumber/cucumber-jvm/tree/v4.0.0/junit，如果您配置<parallel> and <threadCount>相应地在你的 POM 中，并使用依赖注入来共享状态（我正在使用 Pico Continer），那么你的 Cucumber 功能应该并行执行。
然而，当我运行 Maven 时，它仍然一次只执行一项功能。
我在下面包含了完整的 POM - 有人可以帮忙吗？

如果有帮助，下面是我的运行程序类（com.softwareautomation.world 是 DI 类）
package com.evasoftwareautomation.runners;
import org.junit.runner.RunWith;
import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
@RunWith(Cucumber.class)
@CucumberOptions(
plugin = {"pretty", "html:target/cucumber", "junit:target/cucumber.xml"},
features = "src/test/resources/com/softwareautomation/features",
glue = {"com.softwareautomation.stepdefs", "com.softwareautomation.world"},
junit ={ "--step-notifications"},
monochrome = true)
public class CucumberTest {
}
请参阅下面从 Maven 运行时失败的堆栈跟踪：
