Intellij IDEA私有构造函数测试范围

Question

这是我的实用程序类

public class LocationMapper {

@ lombok.experimental.UtilityClass批注创建私有构造函数

当我进行测试时，总是只覆盖75％的代码。剩下的25％是此行

IntelliJ IDEA 2020.2.3 (Community Edition)

我认为是因为代码无法访问，但Intellij应该在覆盖范围内忽略私有构造函数

这是我的IDE中的错误还是我做错了什么？

input=[ {key:"name", value:"John"}, {key:"city", value:"Chicago"}]

output = input.map( e => **magic here** );
>> output = [ {name:"John"}, {city:"Chicago"}]
