我试图模拟Scala单例对象.特别是,我需要模拟play.api.libs.ws.WS服务组件(被测试的类)中使用的对象.使用Mockito这是不可能的,测试执行失败的方式如下:

[error]    MockitoException: : 
[error] Cannot mock/spy class play.api.libs.ws.WS$
[error] Mockito cannot mock/spy following:
[error]   - final classes
[error]   - anonymous classes
[error]   - primitive types  (GeolocationSpec.scala:18)

在这里阅读,似乎Scalamock允许这样做:

要模拟独立的单例对象,请使用 org.scalamock.annotation.mockObject.

我的服务组件是这样的:

trait GeolocationService {
  def wsClient = WS
  def getPath(origin: Location, destination: Location): Future[Route]
}

class DefaultGeolocationService extends GeolocationService {

  val serviceProviderEndpoint = Play.current.configuration.getString("api.directions.endpoint")

  override def getPath(origin: Location, destination: Location): Future[Route] = {

    val params = Seq(
      "origin" -> s"${origin.lat},${origin.lon}",
      "destination" -> s"${destination.lat},${destination.lon}"
    );
    val resp …
