我有一个使用 Typesafe Slick (v 1.0.1) 的 Play (v 2.2.0) 应用程序，我正在尝试编写一个为 PostgreSQL 数据库播种的测试 (specs2)，然后调用各种控制器操作以验证数据的存在。在我的测试中，我有：

 "Countries" should {
      "initialize" in {
        running(FakeApplication(additionalConfiguration = inMemoryDatabase())) {
          AppDB.database.withSession {
            implicit session: Session =>

              AppDB.dal.create
              AppDB.dal.seedForTests

              AppDB.dal.Countries.findAll().size must be_>=(1)
          }
        }
      }

就其本身而言，这很好用。但是，当我添加另一个测试操作时，例如：

  "respond to Index()" in {
    val result = controllers.Countries.index()(FakeRequest())

    status(result) must equalTo(OK)
  }

我的测试失败并显示以下消息：

SQLException: Attempting to obtain a connection from a pool that has already been shutdown.

堆栈跟踪的相关部分是：

[error]     SQLException: Attempting to obtain a connection from a pool that has already been shutdown. 
[error] Stack trace of location where pool was shutdown follows:
[error]  java.lang.Thread.getStackTrace(Thread.java:1503)
[error]  com.jolbox.bonecp.BoneCP.captureStackTrace(BoneCP.java:559)
[error]  com.jolbox.bonecp.BoneCP.shutdown(BoneCP.java:161)
[error]  com.jolbox.bonecp.BoneCPDataSource.close(BoneCPDataSource.java:143)
[error]  play.api.db.BoneCPApi.shutdownPool(DB.scala:414)

[error]  play.api.db.BoneCPPlugin$$anonfun$onStop$1.apply(DB.scala:262)
[error]  scala.collection.immutable.List.foreach(List.scala:318)
[error]  play.api.db.BoneCPPlugin.onStop(DB.scala:262)
...

我尝试将代码中的FakeApplication(...)和AppDB.database.withSession块都移到更高的位置，并将代码包装val result = controllers.Countries.index(...)在AppDB.database.withSession包装器中，但仍然没有运气。

谢谢你的任何指导。

您可以使用它AroundExample来初始化您的数据库并运行您的测试：

class CountriesSpec extends mutable.Specification with AroundExample {

  def around[R : AsResult](r: =>R) = 
    running(FakeApplication(additionalConfiguration = inMemoryDatabase())) {
      AppDB.database.withSession { implicit session: Session =>
        AppDB.dal.create
        AppDB.dal.seedForTests
        AppDB.dal.Countries.findAll().size must be_>=(1)
        // just AsResult(r) with the latest 2.2.3 specs2 
        AsResult.effectively(r)
      }
    }

  "Countries" should {
    "respond to Index()" in {
      val result = controllers.Countries.index()(FakeRequest())
      status(result) must equalTo(OK)
    }
  }
}
