maven - 为什么 TestNG 会多次运行这些测试类？

Question

我正在 CI 服务器 (Bamboo) 上运行构建和测试。我正在使用 TestNG 运行我的集成测试。

当我运行我的构建和测试(使用 Maven)时，我在日志中看到以下内容(这是一个示例，还有其他类也受到影响)

我感到困惑的是 c.v.p.i.c.MultiChannelContentServiceIntegrationTest$XX 的实例。

我没有故意或明确要求这些类运行多次，它们似乎也没有运行多次(因为它们报告 Test runs: 0 除了一个实例)。

谁能指出我这里可能发生的事情。这种现象并不真正适合谷歌搜索。大多数“使用 TestNG 进行多次测试运行”的搜索都解释了如何有意地进行。

Answer 1

你的测试类中有没有匿名内部类？就是这样MultiChannelContentServiceIntegrationTest$22 等似乎表明。

显然，模式

<include>c/v/p/integration/**/*.java</include>

包含这些匿名类，因此 Surefire 尝试将它们作为测试类运行。

试试 **/*Test.java 或简单地使用默认值。
