scala - 如何通过 ScalaMock 使用受保护的抽象方法存根抽象 java 类？

Question

我正在尝试存根抽象java.nio.channels.ServerSocketChannel类但得到了

Error:(15, 18) object creation impossible, since:
it has 2 unimplemented members.
/** As seen from <$anon: java.nio.channels.ServerSocketChannel>, the missing signatures are as follows.
 *  For convenience, these are usable as stub implementations.
 */
  protected[package spi] def implCloseSelectableChannel(): Unit = ???
  protected[package spi] def implConfigureBlocking(x$1: Boolean): Unit = ???
    socket = stub[ServerSocketChannel]

当然我可以在测试子类中覆盖这些方法，但也许有更优雅的解决方案？

Answer 1

宏 Mocks 是要模拟的类型的子类。因此它们遵守与 Scala 中常规类层次结构相同的限制。除了直接依赖抽象类，您可以使用接口，例如NetworkChannel并模拟它吗？

扩大方法可见性的示例：

package java.nio.channels;

abstract class ServerSocketChannelSub extends ServerSocketChannel {
  def implCloseSelectableChannel(): Unit
  def implConfigureBlocking(x: Boolean): Unit
}

然后在你的测试中

val socketChan = mock[ServerSocketChannelSub]

构造这个子类的实例的所有副作用也将适用于每个模拟，没有办法解决这个问题。
