[英]Maven - Failsafe plugin is not running cucumber tests in parallel
[英]Maven failsafe plugin doesn't run parallel Test
我有一个Maven POM文件,当我提供并行执行选项时,我没有在日志中看到任何并行执行的迹象。 XML调试让我疯狂。 有什么想法吗?

问题 - 当并行执行选项传递给failsafe插件时,日志应该如何确认并行执行测试?
UPDATE
我注意到当我为maven设置debug选项来执行时,我注意到parallelExecution被设置为false

任何想法为什么会这样?
谢谢
首先,确保您强制使用特定的jUnit提供程序,因为已知旧版本(<4.7)存在并发执行问题 。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<version>2.16</version>
<dependencies>
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit47</artifactId>
<version>2.16</version>
</dependency>
</dependencies>
</plugin>
您可以使用forkCount
进行并发执行选项而不是parallel
。 我发现它更灵活,并且由于每个测试都在自己的JVM中运行,因此您可能会遇到较少的并发问题,这可能会使您的测试结果不确定。 这些配置适用于maven-surefire-plugin
和maven-failsafe-plugin
。
<forkCount>8</forkCount>
<reuseForks>true</reuseForks>
您可以组合forkCount
和parallel
,但forkCount
, reuseForks
等的不同组合使事情变得更复杂。 请注意以下文档 :
当使用reuseForks = true且forkCount值大于1时,测试类将逐个移交给分叉进程。 因此,parallel = classes不会改变任何东西。 但是,您可以使用parallel = methods:在forkCount并发进程中执行类,然后每个进程可以使用threadCount线程并行执行一个类的方法。
我不确定报告是否会告诉您测试是否以并发模式运行,但我知道它们正在运行的方式是使用top
或htop
(在Linux或OS X上)。 这是我的测试运行的截图。 您可以看到多个JVM运行测试并消耗CPU。 我的测试也以这种方式运行得更快。
