监视类的所有实例。我们要做的就是在创建实例之前调用mockkConstructor(MyObject::class)。现在我想在adnroid Views上做到这一点（在robolectric的帮助下）
像mockkConstructor(MyCustomView::class)
这是我们实例化自己的简单java对象的方法 不像系统实例化的Android视图
以下测试成功通过
@Test
fun mockingConstructor() {
//with
mockkConstructor(Car::class)
//from now all Car instances acts as if they are a <<spy>>
every { anyConstructed<Car>().wheelsCount() } returns 6
//assertions
assertEquals(Car("plate-number1").wheelsCount(), 6) //pass
assertEquals(Car("plate-number2").wheelsCount(), 6) //pass
assertEquals(Car("plate-number3").wheelsCount(), 6) //pass
//other functions work as implemented in their classes like :
assertEquals(Car("plate-number4").drive(), "now driving") //pass
}
问题
这就是我尝试监视失败
的android视图的方法@RunWith(RobolectricTestRunner::class)
class TestClass {
@Test
fun test2() {
mockkConstructor(MyCustomView::class)
//a simple empty activity that uses myCustomView in its layout.xml
val activity = Robolectric.setupActivity(NavTestActivity::class.java)
}
}
错误
这是我得到的错误::
