我有以下课程
class GlobalFieldTitleMapper @Inject constructor() {
fun toTitleMap(rawApiResponse: List<Map<String, Any>>): HashMap<Any, Any> {
val titles = HashMap<Any, Any>()
val globalHashMap = rawApiResponse.findLast { it.containsKey("global") }
val globalValue = globalHashMap?.get("global") as Map<*, *>
val boxAttributes = globalValue["boxattributes"]?.let { it as Map<*, *> }
boxAttributes?.forEach { key, value ->
titles[key!!] = (value as Map<*, *>)["boxtitle"]!!
}
return titles
}
}
我想在单元测试中模拟此方法：
@Mock
private lateinit var globalFieldTitleMapper: GlobalFieldTitleMapper
@Before
fun setup() {
MockitoAnnotations.initMocks(this)
recoRepo = RecommendationsRepo(recommendationsApi, SALESLINE, sessionInfo, productModuleMapper, globalFieldTitleMapper)
whenever(globalFieldTitleMapper.toTitleMap(any())).thenReturn(hashMapOf())
}
但是Mockito抛出以下错误：
org.mockito.exceptions.base.MockitoException:
Mockito cannot mock this class: class com.mediasaturn.app.home.recommendations.GlobalFieldTitleMapper.
Can not mock final classes with the following settings :
- explicit serialization (e.g. withSettings().serializable())
- extra interfaces (e.g. withSettings().extraInterfaces(...))
You are seeing this disclaimer because Mockito is configured to create inlined mocks.
You can learn about inline mocks and their limitations under item #39 of the Mockito class javadoc.

我尝试了几种方法，例如设置显式类型（例如，代替参数中的Any），还临时将返回类型更改为String。一切都没有成功。我认为Mockito并不关心我的方法的实现，而仅关心函数的签名，但是我仍然不明白我在做什么。这是我定义模拟方法的方式-我也尝试设置一个显式对象而不是hashMapOf()。也没有成功。我为每次输入感到高兴。
编辑： mock-maker-inline 已启用，并且可用于其他Kotlin类
我也尝试在班级上使用open关键字-运行测试时，出现以下错误
org.mockito.exceptions.base.MockitoException:

答案 0 :(得分：0)
Mockito可以模拟非开放式Kotlin类（或最终的Java类），但是您需要打开此功能，因为它可能会改变行为并影响模拟性能（您可能不会注意到） This answer解释了如何在这种情况下启用模拟。
