How to write the unit test to mock Metadata.getInfo call

[shitai-chen]

Hi folks,

I was trying to write an unit test for this piece of code.

const metadataData = new Metadata(
      accountAddress, // "6QALsbKrycLP13Pad2puZu2ohCtvcJh2yGy6N3dAFYJr" for example
      await Metadata.getInfo(connection, accountAddress),
    ).data;

because in the unit test, it's better not to do a real rpc call. So I want to mimic the call to return the metadataData. I used jest framework, but I don't know how to mimic this. Any ideas?

Thanks in advance.
