Rails/Rspec: How to specify a specific form when using "fill_in"

I have two forms on a page - one for login, one for signup, and both share a field called "user[username]"

When running integration tests in rSpec, how do I specify that I want actions to be run on a specific form?

You just need add some scope define by css selector. So you just need to say you want fill user[name] form in form #login_form or #signup_form
