Java jvm4.0.0和Junit测试运行程序没有并行执行

我无法使用jvm4.0.0和junittestrunner并行运行特性。我只打开了一个浏览器实例，一旦执行完成，浏览器将关闭并再次打开以执行下一个功能。根据我在Maven surefire中的线程计数3，我希望同时打开3个浏览器实例以运行3个功能。我遵循了以下几点，但仍然没有成功。这些功能一个接一个地运行。我已经使用Pico容器进行DI。我按照这个更新了不同版本的Surefire插件，但仍然没有成功。我试过4.0.0和4.2.0来制作IO.cucumber罐子。我尝试过2.19到2.22的不同版本的surefire，但仍然没有成功。我有3个功能文件，每个文件都有一个场景大纲标记为“@Parallel”。我不确定哪里出了问题。我在surefire插件中尝试过并行作为“两者”和“方法”。我的Junit版本是4.12

我的pom如下

我怀疑您可能打算在配置中使用

maven-surefire-plugin

而不是

maven-surefire-report-plugin

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.22.0</version>
            <configuration>
                <parallel>methods</parallel>
                <threadcount>3</threadcount>
            </configuration>
        </plugin>

org.apache.maven.plugins
maven surefire插件
2.22.0
方法
3.

这可能无关紧要

我尝试用Junit实现Cucumber，因为它在特性级别上的并行限制，所以我转向Cucumber TestNG

TestNG it自身支持Junit。因此，在当前的设计中，只有runner类需要更改

请看一下这一次

---

这是通过Cucumber TestNG实现的，并且支持场景级别的并行执行。

您应该使用maven failsafe插件，而不是surefire。 我将failsafe与com.github.temyers-cucumber jvm并行插件结合使用，我也遇到了同样的问题（尝试在pom中启用并行，但功能似乎是按顺序运行的）

在搜索过程中，我发现了这个bug，它声称在maven with testng中忽略了并行和线程计数配置。然后我意识到我对testng有依赖性，而我根本没有使用它（除了一些我切换到使用junit的断言）

---

我可以在您的pom中看到对testng的依赖。您可以尝试删除依赖项，或者确保使用一个解决了testng问题的版本，然后重试。

您可以尝试删除testng依赖项，或者明确地说使用surefire junit 像

org.apache.maven.plugins
链接不起作用。请尝试此操作。此操作是否支持AppiumDriver for mobile？问题是针对Cucumber，JUnit提出的，您回答了Cucumber，TestNG。你有正确的答案吗？我在原来的问题中更改了surefire配置。我在Pom中只使用了surefire¬ report插件。Cucumber从v4.0.0开始就支持并行执行。不再需要并行插件。添加依赖项修复了它。感谢您解决了我1小时的调试问题
