我正在尝试合并一个 maven 插件 cucumber-jvm-parallel-plugin 进入我的 Cucumber-JVM 代码并遇到一些问题......我想我已经正确配置了我的 pom.xml，但是我的黄瓜 功能是仍然一个接一个运行，而不是并行运行.
I am trying to incorporate a maven plugin cucumber-jvm-parallel-plugin into my Cucumber-JVM code and am running into some problems... I think I have configured my pom.xml properly, but my cucumber features are still getting ran one by one instead of in parallel.
如何配置我的 pom.xml 以使我的黄瓜功能并行运行?我有一些功能文件会阻止执行，我不想等待它们完成为了开始测试其他功能.
How do I configure my pom.xml to make my cucumber features run in parallel? I have some feature files that block execution and I don't want to have to wait for them to finish in order to start testing the other features.
我遵循了两个教程，但找不到哪里出错了，或者如果这是预期的:
I followed two tutorials, and can't find where I am going wrong, or if this is expected:

Maven Pom 逻辑
我的pom配置方式如下:
Maven Pom Logic
The way I configured my pom is as follows:
我使用 Maven 资源插件
I copy ../../features/api/ to my build path using Maven Resources Plugin
<build>
<resources>
<resource>
<directory>../../features/api/</directory>
</resource>
</resources>
</build>
我告诉 cucumber-jvm-parallel-plugin我的 features 现在位于 target/classes/active/，因为我认为 ../../features/api/ 已复制到target/，所以 target/active/ 应该包含我的 .feature 文件.我认为.
I tell cucumber-jvm-parallel-plugin that my features are now located at target/classes/active/, because I think ../../features/api/ was copied to target/, so target/active/ should contain my .feature files.. I think.
<plugin>
<groupId>com.github.temyers</groupId>
<artifactId>cucumber-jvm-parallel-plugin</artifactId>
...
<configuration>
...
<featuresDirectory>${project.build.directory}/classes/active/</featuresDirectory>
...
</configuration>
</plugin>
然后，在我运行 maven test 之后，所有的 .feature 文件都会被编译成 target/test-classes/Parallel**IT.类.每个功能文件一个.
Then, after I run maven test, all .feature files are then compiled into target/test-classes/Parallel**IT.class. One per feature file.
所以我告诉 maven-surefire-plugin 并行运行所有<include>**/Parallel*IT.class</include>文件，即cucumber创建的特征文件-jvm-parallel-plugin.
So I tell maven-surefire-plugin to run all <include>**/Parallel*IT.class</include> files in parallel, which are the feature files created by cucumber-jvm-parallel-plugin.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<executions>
<execution>
<id>acceptance-test</id>
<phase>integration-test</phase>

<includes>
<include>**/Parallel*IT.class</include>
</includes>
</configuration>
</execution>
</executions>
</plugin>

黄瓜跑者
而我的黄瓜跑课是这样的:
Cucumber Runner
And my cucumber running class looks like this:
@RunWith(Cucumber.class)
@CucumberOptions(plugin={"pretty","json:../../results/api-json.json"}, glue={"com.mycompany.commonapps.queuemanager"}, features={"../../features/api/active"})
public class RunApiTest {
}
输出
当我运行 mvn test 时，我得到以下信息:

When I run mvn test, I get the following:

有人看到我做错了吗?
cucumber-jvm-parallel-plugin 的outputDirectory 正在正确创建并包含一堆 Parallel**IT.class 文件cucumber-jvm-parallel-plugin 的 featuresDirectory 正在正确访问.cucumber-jvm-parallel-plugin 的 cucumberOutputDir 根本没有在构建后创建.
cucumber-jvm-parallel-plugin's outputDirectory is getting created correctly and contains a bunch of Parallel**IT.class files
cucumber-jvm-parallel-plugin's featuresDirectory is getting accessed correctly.
cucumber-jvm-parallel-plugin's cucumberOutputDir is NOT getting created at all after a build.
推荐答案
我终于搞定了！为了让我的测试并行运行，我必须这样做:
I finally got it to work! Here's what I had to do to make my tests run in parallel:
我将 maven-surefire-plugin execution 标签中的一些字段移至 configuration 标签.我移动了这个部分:
I move some fields in the maven-surefire-plugin execution tag to the configuration tag. I moved this section:
<forkCount>5</forkCount>
<reuseForks>true</reuseForks>
<includes>
<include>**/*IT.class</include>
</includes>
所以我的 maven-surefire-plugin 现在看起来像这样:
So that my maven-surefire-plugin now looks like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<forkCount>5</forkCount>
<reuseForks>true</reuseForks>
<includes>
<include>**/*IT.class</include>
</includes>
</configuration>
</plugin>
由于 cucumber-jvm-parallel-plugin 现在正在运行该节目，我不得不删除我的 cucumber runner 类.我是这样评论的:
Since cucumber-jvm-parallel-plugin is now running the show, I had to remove my cucumber runner class. I commented it out like this:
/*
@RunWith(Cucumber.class)
@CucumberOptions(plugin={"pretty","json:../../results/api-json.json"}, glue={"com.mycompany.commonapps.queuemanager"}, features={"../../features/api/active"})
*/
public class RunApiTest {
}
就是这样.由于创建了 Parallel**IT.class，所以 maven-surefire-plugin 无法正常工作.
And that's it. Since Parallel**IT.class where getting created, it was maven-surefire-plugin that was not working right.
