用Mockk模拟ObjectMapper扩展函数

  •  0
  • Dean  · 技术社区  · 6 年前

    我一直在尝试使用 Mockk 模拟Jackson的以下扩展函数 ObjectMapper :

    inline fun <reified T: Any> ObjectMapper.convertValue(from: Any): T = convertValue(from, jacksonTypeRef<T>())
    

    文档表明我需要这样做:

    mockkStatic("com.fasterxml.jackson.module.kotlin.ExtensionsKt")
    every {
       ObjectMapper().convertValue<SNSEvent>(any<Map<String, Any>>())
    } returns event  
    

    java.lang.AbstractMethodError: Method net/bytebuddy/renamed/java/util/Map$ByteBuddy$smykbfJj.isEmpty()Z is abstract

    另一个尝试是更改它,以便它接受将要传递的实际映射:

     mockkStatic("com.fasterxml.jackson.module.kotlin.ExtensionsKt")
        every {
            ObjectMapper().convertValue<SNSEvent>(map)
        } returns event
    

    这会产生另一个错误:

    再次阅读文档时,会发现类名可能是意外的:

    这是标准的Kotlin行为,对于mocking库的用户来说可能是不可预测的。使用工具->Kotlin->显示Kotlin字节码或检查JAR存档中的.class文件来检测此类名称。

    因此,我解压缩了jar并发现了以下类 com.fasterxml.jackson.module.kotlin.ExtensionsKt$convertValue$$inlined$jacksonTypeRef$1.class 我试着用它来代替:

       mockkStatic("com.fasterxml.jackson.module.kotlin.ExtensionsKt\$convertValue\$\$inlined\$jacksonTypeRef\$1")
        every {
            ObjectMapper().convertValue<SNSEvent>(map)
        } returns event
    

    这产生了相同的错误并记录了另一个错误:

    我知道一个可能的解决方案是不使用扩展函数,而是使用原来的Java convertValue 功能。如果可能的话,我可以在mock代码中使用它们。
