无法从maven运行testNG测试

Question

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main函数，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类在运行，而实际的测试并没有运行。以下是我的pom.xml文件：

testng.setXmlSuites(mySuites);

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

我想知道我错过了什么。

Answer 1

最后，我找到了一个解决方案，我只需要加上

<classpathScope>test</classpathScope>

到exec插件的配置，现在它按预期工作。
