无法覆盖 withFixture（测试：OneArgTest）

Question

import org.scalatest.fixture.Suite.OneArgTest

class PingPongActorSpec extends TestKit(ActorSystem("PingPongActorSpec")) 
  with ImplicitSender with FlatSpecLike with Matchers with BeforeAndAfterAll {

  override def withFixture(test: OneArgTest) = {}
}

当我试图用 'OneArgTest' 类型的测试覆盖 withFixture 方法时，编译器给我以下错误消息：

object Suite 不是包的成员 org.scalatest.fixture 注意：trait Suite 存在，但它没有伴随对象。
未找到：键入 OneArgTest

Answer 1

只需删除您的导入。 OneArgTest 是 Suite 特性中的内部保护特性，因此它可以在 Suite 的后代中使用而无需导入。这个应该工作：

class PingPongActorSpec extends TestKit(ActorSystem("PingPongActorSpec")) 
  with ImplicitSender with FlatSpecLike with Matchers with BeforeAndAfterAll {

  override def withFixture(test: OneArgTest) = {}
}

Answer 2

而不是混合特征“FlatSpecLike”：

class PingPongActorSpec extends TestKit(ActorSystem("PingPongActorSpec")) 
  with ImplicitSender with FlatSpecLike with Matchers with BeforeAndAfterAll  {
  override def withFixture(test: OneArgTest) = {}
}

我们需要混合特征 "fixture.FlatSpecLike":

class PingPongActorSpec extends TestKit(ActorSystem("PingPongActorSpec")) 
  with ImplicitSender with fixture.FlatSpecLike with Matchers with BeforeAndAfterAll
  override def withFixture(test: OneArgTest) = {}
}

这解决了问题。

Answer 3

您需要使用org.scalatest.flatspec.FixtureFlatSpecLike

import org.scalatest.flatspec.FixtureFlatSpecLike

class PingPongActorSpec extends TestKit(ActorSystem("PingPongActorSpec")) 
      with ImplicitSender with FixtureFlatSpecLike with Matchers with BeforeAndAfterAll { ...
