我们使用 GuiceApplicationBuilder 通过 fakeApplication 设置 Playframework 测试
class BaseSpec extends AnyFunSpec/PlaySpec with GuiceOneAppPerSuite {
override def fakeApplication(): Application = new GuiceApplicationBuilder()
.disable[PlayModule]
.disable[JobSchedulerModule]
.build()
}
我们有（经过净化的）测试设置，例如
import BaseSpec
class SampleSpec extends BaseSpec {
"test suite" should {
"test case" in {
.....
}
}
}
每当我们运行测试时，我们都会得到：
A needed class was not found. This could be due to an error in your runpath. Missing class: play/Configuration

不需要假应用程序的测试不会抛出此异常。 此异常是我们尝试从旧版本升级应用程序的结果。 我们尝试更改 GuiceOneAppPerSuite 的逻辑，但它不起作用。 我们尝试升级PlayFramework的版本，仍然不行。 我们可以确认播放/配置是我们运行路径的一部分。
该错误让我认为您正在使用 Java 导入而不是 Scala 导入。 Play 的某些类在不同的包下可用于 Java 和 Scala。
