使用scalamock部分模拟类

import org.scalamock.scalatest.MockFactory
import org.scalatest.{FlatSpec, Matchers}

class MyService {
  def getDataFromExternalService(): String = {
    // 调用外部服务获取数据
    // ...
    "Data from external service"
  }
  
  def processData(data: String): String = {
    // 处理数据
    // ...
    "Processed data"
  }
  
  def doSomething(): Unit = {
    val data = getDataFromExternalService()
    val processedData = processData(data)
    // 做一些其他操作
    // ...
  }
}

class MyServiceSpec extends FlatSpec with Matchers with MockFactory {
  "MyService" should "do something" in {
    val mockService = mock[MyService]
    (mockService.getDataFromExternalService _).expects().returning("Mocked data")
    (mockService.processData _).expects("Mocked data").returning("Mocked processed data")
    
    mockService.doSomething()
    
    // 验证结果
    // ...
  }
}
