使用testng，mavensurefire插件和黄瓜jvm并行运行测试时获得异常

问题描述 投票：0回答：1

我试图通过使用cucumber-jvm插件自动生成测试运行器并使用maven-surefire插件并行运行来并行执行黄瓜功能文件。运行命令“mvn clean test”时，我收到以下错误

下面是我的POM.xml，testng.xml文件和testRunners。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite" parallel="tests">   <!-- how many scenarios we can execute at a time is mentioned bt data-provider-thread-count-->
    <test name="ChromeTest" thread-count="5">
        <!--  <parameter name="browser" value="chrome"/>-->
        <classes>
        <class name="Parallel02IT"/>
        <class name="Parallel01IT"/>
        </classes>

    </test> <!-- Test -->

        </packages>
    </test>-->

在https://github.com/temyers/cucumber-jvm-parallel-plugin你可以找到

至于cucumber-jvm：黄瓜本身支持4.0.0并行执行。因此，建议升级到Cucumber 4.0.0，不再维护此插件。

请注意，最新版本是4.3.0 https://mvnrepository.com/artifact/io.cucumber/cucumber-testng/4.3.0您的pom文件中有多个不同的版本 - 请统一。通常你的pom文件非常混乱。你需要的只是：

    <!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-server -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-server</artifactId>
        <version>3.141.59</version>
    </dependency>

    <!-- https://mvnrepository.com/artifact/io.cucumber/cucumber-java -->
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-java</artifactId>

    </dependency>

    <!-- https://mvnrepository.com/artifact/io.cucumber/cucumber-testng -->
    <dependency>
        <groupId>io.cucumber</groupId>

    </dependency>

对于并行执行检查https://github.com/cucumber/cucumber-jvm/blob/master/testng/README.md#parallel-execution
