👍 THX!

... do we really need this? Is it a good idea to talk about testing without even showing a test?

I think I'd rather either have nothing about this at all, or a full test case. What do you think?

[rafaelfranca]

I agree that we don't need this. If you want to test any object you can to call .new on the class.

[phoet]

@steveklabnik @rafaelfranca you are missing the point. there is NO example in the readme, that you can actually use .new with serializers.

that's not the readme

as @steveklabnik mentioned, it would be good to have something about testing in the readme. i did not provide an example because my RSpec code would be to specific for that.

[rafaelfranca]

Well, it is not the README but it is still part of the documentation of the project.

Really I don't think we need something to tell people that we can call .new in a class, but if want to write a section about testing go it will be great.

i will provide an example for RSpec and MiniTest, i hope that's enough
