我正在使用 springMVC 和 thymeleaf 使用 Intellij 在 kotlin 中开发一个 spring-boot 应用程序。很简单，在我尝试运行一些测试之前一切正常。测试甚至不相关。事实上，仅仅实例化一个测试似乎就足以让 thymeleaf 发疯。它抛出了数千行异常。

我已经创建了一个带有最小项目设置的 git 存储库，可以在此处重现该问题：https ://github.com/TheNewBob/kotlin-test-thymeleaf

这是我的两个版本的“测试”：

普通的 JUnit：

class ContentServiceTest {
    @Test
    fun test() {
    }
}

工作正常，Intellij 中的控制台输出：

Connected to the target VM, address: '127.0.0.1:45773', transport: 'socket'
Disconnected from the target VM, address: '127.0.0.1:45773', transport: 'socket'

Process finished with exit code 0

但是当我切换到 Kotlintest 时：

class ContentServiceTest :StringSpec()

混乱随之而来：

一遍又一遍地抛出这个错误。我将终端缓冲区重新配置为 10'000 行，但输出仍然不合适。

不过我注意到的是 gradlew 测试运行没有问题，所以 Intellij IDEA 似乎也在其中发挥了作用。

这基本上就是我的难题：spring-boot、thymeleaf、kotlintest 和 IDEA 都参与其中。删除其中任何一个，都没有问题。我不知道哪个是罪魁祸首，否则我可能只是在适当的地方提交问题报告。

以前有没有人遇到过这个问题，或者有预感问题可能出在哪里？
