如何在使用STRICT_STUBS ()时启用Mockito.mock

Question

我只发现了三种在Mockito中启用STRICT_STUBS的方法(见文献)

1. MockitoJunitRunner
2. MockitoJUnit.rule().strictness(Strictness.STRICT_STUBS)
3. Mockito.mockitoSession() .initMocks(this) .strictness(Strictness.STRICT_STUBS) .startMocking()

所有这些都需要通过注释(@Mock lateinit var api: MyApi )来声明存根。但是我使用莫奇托-科特林并像这样声明存根：

val api: MyApi = mock()

或者像这样：

val api:MyApi = mock{
  on { call("expected-param") } doReturn something
}

在遮罩下，它使用Mockit.mock方法。

问题1：当我使用Mockit.mock时如何启用STRICT_STUBS？

问题2：也许可以为所有东西启用STRICT_STUBS，而不管如何定义STRICT_STUBS？

更新1。测试实例

interface Foo {
    fun doFoo(value: String): String
}

class Boo(private val foo: Foo) {
    fun doBoo(value: String): String {
        return foo.doFoo("$value with Boo")
    }
}

class ExampleTest {
    @get:Rule val rule = MockitoJUnit.rule().strictness(Strictness.STRICT_STUBS)
    // doesn't work when replaced with var mockedFoo: Foo = Mockito.mock(Foo::class.java)
    @Mock lateinit var mockedFoo: Foo
    lateinit var booUnderTest: Boo

    @Before fun setUp() {
        booUnderTest = Boo(mockedFoo)
    }

    @Test fun withEmptyString() {
        `when`(mockedFoo.doFoo(" with Boo")).thenReturn("empty boo")
        // should fail, because this interaction is not used
        `when`(mockedFoo.doFoo("Foo with Boo")).thenReturn("complete")
        booUnderTest.doBoo("")
        verifyNoMoreInteractions(mockedFoo)
    }

    @Test fun withRealString() {
        `when`(mockedFoo.doFoo("Foo with Boo")).thenReturn("complete")
        booUnderTest.doBoo("Foo")
        // this test should pass because with STRICT stubbing no need to call verify
        verifyNoMoreInteractions(mockedFoo)
    }
}

当存根被定义为@Mock lateinit var mockedFoo: Foo时，严格的存根工作。当我用var mockedFoo: Foo = Mockito.mock(Foo::class.java)代替它时，严格的固执不再起作用了。

更新2。回答。。如果在启用严格模式后调用Mockito.mock，则可以工作。

class ExampleTest {
    @get:Rule val rule = MockitoJUnit.rule().strictness(Strictness.STRICT_STUBS)
    lateinit var mockedFoo: Foo
    lateinit var booUnderTest: Boo
    @Before fun setUp() {
        mockedFoo = Mockito.mock(Foo::class.java)
        booUnderTest = Boo(mockedFoo)
    }

    @Test fun withEmptyString() {
        `when`(mockedFoo.doFoo(" with Boo")).thenReturn("empty boo")
        // should fail, because this interaction is not used
        `when`(mockedFoo.doFoo("Foo with Boo")).thenReturn("complete")
        booUnderTest.doBoo("")
        verifyNoMoreInteractions(mockedFoo)
    }

    @Test fun withRealString() {
        `when`(mockedFoo.doFoo("Foo with Boo")).thenReturn("complete")
        booUnderTest.doBoo("Foo")
        // this test should pass because with STRICT stubbing no need to call verify
        verifyNoMoreInteractions(mockedFoo)
    }
}

Answer 1

STRICT_STUBS需要额外的逻辑来验证测试后已经调用和未调用的内容，这就是为什么在整个测试级别上对其进行配置的原因。尽管如此，这三种方法中的任何一种都应该使用普通的Mockito.mock方法(并给出示例，只要它在幕后使用Mockito.mock )。
