harmony 做单元测试，打补丁非常灵活，可以绕过很多无法测试的代码

Harmony 方法补丁

Public、Privite 方法都可以进行补丁

	[HarmonyPatch(typeof(MyClass))]
    [HarmonyPatch(nameof(MyClass.Method))]
    public class HookMyClass
    {
        /// <summary>
        /// 前置拦截方法
        /// </summary>
        /// <param name="__result"></param>
        /// <returns></returns>
        [HarmonyPrefix]
        public static bool Prefix(ref string __result)
        {
            //这里可以自定义处理result

            //false不调用原方法，ture调用原方法
            return false;
        }

        /// <summary>
        /// 补丁方法
        /// </summary>
        /// <param name="__result"></param>
        [HarmonyPostfix]
        public static void Postfix(ref string __result)
        { 
        
        }

        /// <summary>
        /// 后置方法
        /// </summary>
        /// <param name="__result"></param>
        [HarmonyFinalizer]
        public static void Finalizer()
        { 
        
        }
    }

属性补丁

    [HarmonyPatch(typeof(MyClass), "MyProperty")]
    public class MyClassPatch
    {
        public static MethodInfo Original;

        [HarmonyPatch(typeof(MyClass), "MyProperty", MethodType.Getter)]
        [HarmonyPrefix]
        public static bool Prefix(ref string __result)
        {
            //Debug.Log("MyProperty: " + __result);
            __result = "替换get到的值";
            return false;
        }

        public static void Patch(Harmony harmony)
        {
            Original = AccessTools.PropertyGetter(typeof(MyClass), "MyProperty");
            harmony.Patch(Original, prefix: new HarmonyMethod(typeof(MyClassPatch), "Prefix"));
        }
    }
