check if something is a buffer

[leore]

Is there a way to check if something is a buffer?

expect(file).to.be.a('buffer') does not work.

Should has this functionality.

You can do file.should.be.instaceof(Buffer)

expect(file).to.be.a(Buffer)

This project wasn't being maintained so I forked this project and created expecting.js. It supports this kind of thing fully:

expect(file).to.be.a(Buffer)

Hope this can help!
