Mocking proto.Message in Go
问题
我编写了一个函数，它接受一个proto.Message对象的列表。根据文档，似乎proto.Message包装了protoreflect.ProtoMessage，其中包含一个名为ProtoReflect() Message的函数。根据文档，Message实现了一些其他函数，这些函数返回protoreflect包引用的类型。
看起来创建一个模拟的proto.Message对象可能需要更多的工作，而且可能不值得，但我不想为了单元测试而经历创建protobuf文件、编译和引用的整个过程。
是否有其他方法可以创建一个模拟的proto.Message对象？
英文:
I wrote a function that takes a list of proto.Message objects. Looking at the documentation, it seems like proto.Message wraps protoreflect.ProtoMessage which contains a single function, ProtoReflect() Message. Looking at the documentation for Message, it implements a number of other functions that return types referenced by the protoreflect package.
It seems that attempting to create a mock proto.Message would be a lot more work that it's worth but I don't want to go through the whole process of creating a protobuf file, compiling it and referencing it just for unit testing.
Is there another way I can create a mock proto.Message object?

在进一步调查后，我决定最好的做法是创建一个实际的protobuf消息：
syntax = "proto3";
package my.package;
option go_package = "path/to/my/package"; // golang
message TestRecord {
string key = 1;
string value = 2;
}
然后将其编译为Golang文件，并根据我的需求进行修改：
$ protoc --go_out=./gopb/ --go_opt=paths=source_relative *.proto
一旦测试文件被创建，我可以删除它或将其保存为记录。

After looking into this further, I decided that the best thing to do would be to create an actual protobuf message:
syntax = "proto3";
package my.package;
option go_package = "path/to/my/package"; // golang
message TestRecord {
string key = 1;
string value = 2;
}
and compile it into a Golang file and then modify it for my own purposes:
$ protoc --go_out=./gopb/ --go_opt=paths=source_relative *.proto
Once the test file has been created, I can delete it or save it as a record.
