when(filterPredicates.shouldSendByTimePeriodFromLastMessage().test(any()).thenReturn(true)

when(filterPredicates.<anyMethodInvoked>().test(any())).thenReturn(true)

您可以注册应答以更改默认返回值。

例如（使用优秀的mockito-kotlin包装器）：

interface Thingy {
    fun foo() : Boolean
    fun bar() : Boolean
}

class ThingyTest {
    @Test
    fun test() {
        val t1 = mock<Thingy>(defaultAnswer = Answer { false })
        println(t1.foo())   // "false"
        println(t1.bar())   // "false"

        val t2 = mock<Thingy>(defaultAnswer = Answer { true })
        println(t2.foo())   // "true"
        println(t2.bar())   // "true"
    }
}

当然，在更复杂的情况下，您可能有返回不同类型的方法，在这种情况下，您需要在answer实现中做一些更聪明的事情！
