Unit testing 模拟Kotlin类不可模拟

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
    }
}

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.

Underlying exception : org.mockito.exceptions.base.MockitoException: Could not modify all classes [class com.mediasaturn.app.home.recommendations.GlobalFieldTitleMapper]

我尝试了几种方法，如设置显式类型（例如，在参数中代替

Any

），还临时将返回类型更改为

String

。一切都没有成功。我认为Mockito并不关心我方法的实现，只关心函数的签名，但我仍然不知道我做错了什么。这是我定义mock方法的方式吗？我还尝试设置显式对象，而不是

hashMapOf（）

。也没有成功。我为每一个意见感到高兴

编辑： mock maker inline已启用，并可用于其他Kotlin类

我还尝试在我的类中使用

open

关键字-当我运行测试时，我得到以下错误

org.mockito.exceptions.base.MockitoException:

Mockito可以模拟非开放的kotlin类（或最终的java类），但您需要打开此函数，因为它可能会改变行为并影响模拟性能（您很可能不会注意到）

---

解释如何在这种情况下启用模拟。

您可能遇到模拟生成器内联功能的限制。签出。它比Mockito处理更多的Kotlin代码，所以它可能能够模拟它。这应该会有帮助。你有没有想过如何避开这个错误？谢谢。你解决这个错误了吗？我认为这不对。我有同样的问题，我有

mock-maker-inline

设置。这看起来像是一个Mockito限制。我在我的项目中用Mockito模拟非开放类，所以它可以工作。检查版本和配置以正确设置。
