并行执行没有发生在Cucumber JVM 4.0.0和Junit测试运行器上

Posted 2021-05-05

我无法使用黄瓜JVM 4.0.0和Junit testrunner并行运行功能。我只有一个浏览器实例打开，一旦执行完成，浏览器关闭并再次打开以执行下一个功能。根据我在Maven surefire中的3个线程数，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link，但仍然没有成功。功能一个接一个地运行。我使用Pico容器进行DI.I跟着这个link更新不同版本的Surefire插件但仍然没有运气。我为IO.cucumber Jars尝试了4.0.0和4.2.0。我已经尝试过从2.19到2.22的不同版本的surefire但仍然没有运气。我有3个功能文件，每个都有一个标记为“@Parallel”的场景大纲。我不知道哪里出错。我试过并行surefire插件中的“both”和“methods”。我的Junit版本是4.12。

我的pom如下。

glue={"Stepdef_new.stepdefinitions"},

}

Public class TestRunner{
}    

答案

这可能是无关紧要的。

我试图用Junit实现Cucumber，因为它在功能级别上是并行的限制，我转移到了Cucumber-TestNG。

TestNG它自己支持Junit。因此，只有当前设计需要改变跑步者类别

请看一下https://github.com/bhargavQA/selenium-java-cucumber-framewrok.git

这是使用Cucumber TestNG完成的，并支持场景级别的并行执行。

另一答案

我怀疑你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>

另一答案

你应该使用maven-failsafe-plugin，而不是万无一失。我将failafe与com.github.temyers -cucumber-jvm-parallel-plugin结合使用

另一答案

我有同样的问题（尝试在pom中启用并行，但功能似乎按顺序运行）。

在搜索时我发现这个bug https://github.com/cbeust/testng/issues/987声称在使用testng的maven中忽略了parallel和threadcount配置。然后我意识到我依赖于testng而我根本没有使用它（除了一些断言，我转而使用junit）。

我可以在你的pom中看到对testng的依赖。您可以尝试删除依赖项或确保使用一个修复了testng问题的版本，然后重试。
