测试单个包会跳过 TestNG 中的参数化测试

Question

总体描述

我有一个带有参数化 TestNG 测试的简单 Maven 项目。该参数是通过套件 XML 文件指定的。当我为整个项目运行测试时，会读取套件 XML 文件，使用参数并执行参数化测试。但是，当我尝试仅测试单个包时，显然没有使用套件 XML 文件，并且测试被跳过，并出现诸如“@Test on method ...需要参数'...'之类的投诉，但有未标记为@Optional 或已定义”。问题是如何运行单独的测试和带有参数的测试包。

更多详情见下文。

测试整个项目

这按预期工作。执行两种测试方法。一种测试方法是无参数的，另一种是参数化的，参数值取自套件 XML 文件。这相当于 NetBeans 中的 Run\Test 项目。

测试单个包

在这种情况下，只运行一种测试方法，即无参数的一种。参数化测试方法被跳过。这相当于在 NetBeans 中右键单击一个包并选择“测试包”。

对于单独的包，您需要单独的 XML 文件。当使用包作为参数运行 TestNG 时，TestNG 不会自动知道 XML 文件，就像它不存在一样。 所以你有多个选项，在属性文件中指定参数，或者硬编码它们，或者为每个包创建单独的 XML 文件，然后你可以作为参数传递。
