Question

如何在每次测试之后或之前使用inMemoryDatabase重置FakeApplication中的数据库？我希望每次测试后数据库的状态都返回到初始状态。回滚或清除数据库并再次运行SetupData（）就可以了。

我尝试了很多不同的东西。在每次测试之间永远不会重置数据库。我该怎么做呢？运行以下测试套件时，数据库的状态将继续从测试到测试。因此，如果我在Test2中修改了一些数据，那么它正在影响Test3。

trait TestUtil {
  /**
   * Executes a block of code in a running application.
   */
  def running[T](fakeApp: FakeApplication)(block: => T): T = {
    synchronized {
      try {
        Play.start(fakeApp)
        setup_data()
        block
      } finally {
        Play.stop()
      }
    }
  }

  def setup_data() = {
    //add data to the database
  }
}

我尝试使用上述特性让Play App在每次测试后停止，但它没有帮助。

@RunWith(classOf[JUnitRunner])
class ConditionTests2 extends Specification with TestUtil {
  sequential  // Make the tests run sequentially instead of in parallel

  // test1
  "element with id 1" should {
    "should have name PETER" in {
      running(new FakeApplication(additionalConfiguration = inMemoryDatabase("test"))) {
        // name should be "PETER"
      }
    }
  }

  // test2
  "renaming element with id 1" should {
    "successfully modify element 1" in {
      running(new FakeApplication(additionalConfiguration = inMemoryDatabase("test"))) {
        // Set Name = "John"
      }
    }
  }

  // test3
  "element with id 1" should {
    "should have name PETER" in {
      running(new FakeApplication(additionalConfiguration = inMemoryDatabase("test"))) {
        // name should be "PETER"
        // fails because name is now JOHN
      }
    }
  }
}
