Are there any examples of unit tests with Multer ?

Hi everyone,

I've just finished adding Multer to my project, however, now I've got write some unit tests.

Is there any easy way to mock how Multer work's without adding a bunch of complexity ?

I want to be able to test the following:

• File type validation
• Successful upload
• Unexpected system errors

Can you provide a minimal code you want to test?
