无法从 Maven 运行 testNG 测试

【问题描述】：

我有一个使用 testng API 动态创建 testng.xml 文件的项目，因此使用 java 的主要功能，我的项目按预期工作，但是如果我使用 'Run as->maven build' 通过 maven 运行我的项目看起来只有 BeforeSuite 和 BeforeTest 类正在运行，但实际测试没有运行。这是我的 pom.xml 文件：

这是我的 MainRunner.java 类：

package main;

import java.io.IOException;

import org.testng.TestNG;

import framework.CreateXml;

public class MainRunner {

    public static void main(String[] args) throws IOException {
        // TODO Auto-generated method stub
        TestNG testng= new TestNG();
        CreateXml createAndRun = new  CreateXml(testng);
        createAndRun.createAndRun();

    }

}

此 MainRunner 类调用创建 testng.xml 套件并运行测试的“createAndRun()”函数，如下所示：

testng.setXmlSuites(mySuites);

        testng.setListenerClasses(listenerClasses);
        testng.setVerbose(3);
        testng.run();

最后，这是堆栈跟踪：

我想知道我在这里错过了什么。

【问题讨论】：

    标签： java maven selenium testng maven-surefire-plugin


    【解决方案1】：

    将此添加到您的 Pom.xml 文件中，在您放置 testng 源位置的位置 src/main/java 或 src/test/java 或 src/test/resources

     <configuration>
 <suiteXmlFiles>
 <suiteXmlFile>src/test/resources/testng.xml</suiteXmlFile>
 </suiteXmlFiles>
 </configuration>

    【讨论】：

    • 我没有 testng.xml 文件，它是在运行时创建的，所以不知道如何处理
    • 您在创建 testng.xml 文件时犯了错误。等我发一下。
    • 实际上我的 testng.xml 文件是根据 excel 表中的值动态创建的。因此，一旦创建了 testng.xml 文件，我就使用“testng.run()”运行它。当我将它作为 java 应用程序运行时它可以工作，但在通过 maven 运行时会产生问题。
    • 其实我理解你在说什么。我以为你已经通过编写 java 代码来创建 testng.xml 来生成它。你试过吗？
    • 是的 testng.xml 是由 java 代码在内部生成的，如果我们作为 java 应用程序运行，项目可以工作，唯一的问题是 maven。试图弄清楚。
    【解决方案2】：

    终于找到了解决办法，只需要补充一下

    <classpathScope>test</classpathScope>

    到 exec 插件的配置，现在它按预期工作。

    【讨论】：

    • 您可能希望接受您的回答，以便问题结束。
    • 你忘了说，应该在哪里设置类路径范围。没有那个，你的答案是没有用的。编辑，我将删除反对票。
