NullPointerException 与 json feeder 在测试范围内与 gatling 和 scalatest

Question

我正在尝试使用 scalatest 框架为我的 gatling 项目开发一些测试，但我无法加载我在该项目中使用的 jsonFile。

我总是遇到 nullPointerException。

我将我在主文件夹中使用的资源目录复制到了测试目录，但它从未被识别。我必须为这个范围指定一个数据文件夹吗？

这是我的 pom.xml 中的构建配置：

这是堆栈跟踪：

配置未设置。

我不知道你到底在做什么，但请注意你正在入侵 Gatling 的内部，这些内容可能随时更改，恕不另行通知。
