Maven / Junit并行执行-Cucumber-JVM v4.0.0

时间：2018-10-25 21:35:27

标签： maven selenium junit cucumber-jvm cucumber-junit

我正在努力获得与JUnit / Maven一起使用的Cucumber-JVM v4.0.0的新并行执行功能。

按照指定的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（我正在使用Pico Continer），那么您的Cucumber功能应该并行执行。

但是，当我运行Maven时，它仍然一次仅执行一项功能。

我在下面包括了完整的POM-有人可以帮忙吗？

如果有帮助，下面是我的跑步者班（com.softwareautomation.world是DI班）

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 {
}

从下面的Maven运行时，请参阅失败的堆栈跟踪：

at org.apache.maven.surefire.common.junit48.FilterFactory$GroupMatcherCategoryFilter.shouldRun(FilterFactory.java:207)

您正在使用JUnit 4.12。但是，如上所述，堆栈跟踪告诉我们surefire正在尝试对JUnit 4.8使用集成。您的surefire版本于2012年发布，JUnit 4.12于2014年发布。您是否考虑过更新maven surefire插件？

答案 1 :(得分：0)

我设法通过显式添加测试框架的依赖关系使其工作：

<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>

将其留在此处可能会帮助其他人

就我而言

  • maven没有进行Junit 5测试
  • 黄瓜测试未并行运行

让它起作用

  • 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 

            <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>both</parallel>
            <threadCount>4</threadCount>
        </configuration>
    </plugin>

答案 3 :(得分：0)

就我而言，我使用的是surefire 2.12.4，并将其更新为2.22.2可以达到目的
