playframework迁移到2.4后在playframework中运行测试时出错。x（Java）

1 月，3 周 Questions & Answers

我刚从2.3迁移到2.4。应用程序本身似乎正在运行，但没有一个测试会运行。它们都会失败，并出现以下错误：

我正在使用InjectedRoutesGenerator和webjars play的2.4.0-M3-1版。让我知道，如果有任何其他细节，可能会有所帮助

有人知道会发生什么吗

编辑：

找到这个：https://github.com/sbt/sbt-web/issues/104

这似乎是一个众所周知的问题。我想我会在这期间找到一个创造性的解决办法

    我在测试中通过模拟WebJarAssets类解决了这个问题。测试类中扩展OneAppPerSuite或OneAppPerTest的基本伪应用程序创建代码如下所示：

    implicit override lazy val app: Application = new GuiceApplicationBuilder()
    .in(Environment(new File("."), this.getClass.getClassLoader, Mode.Test))
    .bindings(bind[WebJarAssets].toInstance(mock[WebJarAssets]))
    .build

    在这里，我还混合了org.scalatest.mock.MockitoSugar特征，以便使用mock方法。 我不确定功能测试是否需要完全构造的应用程序，其中可以使用WebJarAssets
