Question

我正在使用Scalamock与ScalaTest，我正在尝试模拟Java接口。我目前有：

private val _iface = mock [MyInterface]

现在我想做

_iface expects `someMethod returning "foo" once

但编译器找不到expects。

我导入了org.scalatest._和org.scalamock.scalatest._。我还缺少什么？

Answer 1

首先，ScalaMock 3中不支持代理模拟，我认为它们将在ScalaMock 4中完全删除。你真的需要使用代理模拟代替宏模拟吗？

这应该有效：

package example

import org.scalatest.FlatSpec
import org.scalatest.Matchers
import org.scalamock.scalatest.proxy.MockFactory

trait MyInterface {
    def someMethod : String
}

class MyTest extends FlatSpec with Matchers with MockFactory {
  "MyInterface" should "work" in {
    val m = mock[MyInterface]
    m.expects('someMethod)().returning("foo")
    m.someMethod shouldBe "foo"
  }
}

如果没有，请查看ScalaMock proxy mocks unit tests了解更多示例。

Answer 2

我认为它应该更像是：

import org.scalamock.scalatest.MockFactory

class MyTest extends FlatSpec with Matchers with MockFactory {
  "MyInterface" should "work" in {
    val m = mock[MyInterface]
    (m.someMethod _).expects().returning("foo")
    m.someMethod shouldBe "foo"
  }
}

我认为期望arg期待arg到函数

Answer 3

我使用scalaMock版4.1.0，这对我有用：

对于某些特征：

trait MyInterface { def someMethod(n1: Int, n2: Int) }

应该对此进行测试

val myInterfaceMock = mock[MyInterface]

myInterfaceMock.someMethod _ expects (1,2)
