我有 2 个测试，在一个 Maven 项目中，我有 Xvfb 从测试开始。我想要实现的是： - 启动 Xvfb 以便测试无头运行 - 运行测试。
但是，当我开始工作时会发生什么： - 测试运行并失败，因为它们找不到显示，因为 xvfb 没有运行 - Xvfb 启动 - 测试再次运行
这是我的 pom.xml

这是我的testng.xml（我不知道它在maven项目中是否有一些作用）：

我的 github 存储库由带有目标文件夹的整个 maven 项目组成，其中始终存储一些测试类的副本。
我的詹金斯工作设置：
- 要求一个 git 存储库，提供链接
- 每当构建 SNAPSHOT 依赖项时构建 - 这是打开的，但它是否打开或关闭都没有区别
- Maven 选项：-Xms256m -XX:MaxPermSize=256m -Xmx256m - 这也与任何事情无关
