所以，我刚刚开始使用Java，我的第二项任务是将涉及两个Java类(一个数据类和一个要运行的类(的程序组合在一起。然而，在我把代码放在一起并抽查错误后，我右键单击代码尝试运行它，但选项变灰了。顺便说一下，我的类使用Netbeans IDE，我正试图使用Maven构建代码。在无法运行代码后，我尝试测试它，但收到了以下错误：
Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12.2:test (default-cli) on project JavaProgramming-app: No tests were executed
运行"；调试测试文件"；期权产生了同样的结果。我试着浏览了这里的论坛，这些论坛提到了类似的问题，并找到了编辑pom.xml文件的常见解决方案，但我复制的大多数代码已经存在于文件中，或者根本没有帮助。下面首先是pom.xml文件，后面是数据类"；订单"；，最后将是运行类"；OrderTest"；。提前感谢您的帮助。

您似乎在使用JUnit测试框架。通常，测试框架依赖于各种机制来发现要运行的测试方法。
基于Netbeans x JUnit的文档：https://netbeans.apache.org//kb/docs/java/junit-intro.html，似乎您需要在测试方法的名称前加上test，以便测试框架运行它
尝试将OrderTests中的public void main(String[] args)方法更改为public void testMain()。
一年前，我在使用相同的Netbeans IDE时也遇到过类似的问题。尝试在pom.xml中添加以下依赖项。这实际上添加了JUnit所需的依赖项。
