Play Scala：在測試中使用Nop Logger來禁止登錄

我想在我的Play框架測試用例中禁止日誌記錄。解決這個問題的一種方法是在類路徑中使用slf4j-nop jar，而不是像logback-classic這樣的其他實現。我能夠在sbt中做到這一點，如下所示。Play Scala：在測試中使用Nop Logger來禁止登錄

libraryDependencies += "org.slf4j" % "slf4j-nop" % "1.7.6" % "test" 

(dependencyClasspath in Test) <<= (dependencyClasspath in Test) map { 
    _.filterNot(_.data.name.contains("logback-classic")) 
}

但我仍然得到下面的錯誤，當我運行我的測試

爲什麼會有上的logback經典的LogbackLoggerConfigurator.scala硬依賴？

這是我的依賴狀態

我有slf4j-nop沒有經驗，但你可以提供test/resources/logback.xml爲測試一種特殊的logback的配置，將覆蓋在conf/logback.xml

一個呀這就是我如何解決了這個問題，但試圖理解爲什麼上述方法沒有，以及如何引入logback-classic的編譯時間依賴性 –
