Create feature specs for Devise OAuth with different providers - ruby-on-rails

Question

I'm writing a Rails app with 100% test coverage. I have feature specs with Capybara for logging in with a username and password, but I don't have specs for logging in through Facebook or LinkedIn.
I didn't find an answer on the devise OmniAuth pages. Is this testable? Should I not be testing this?

Answer 1

I would take a look at https://github.com/plataformatec/devise/wiki/OmniAuth%3A-Overview
So what I’ve ended up creating 2 helpers in my support/omniauth.rb file:
def set_omniauth(opts = {})
default = {:provider => :facebook,
:uuid => "1234",
:facebook => {
:email => "foobar#example.com",
:gender => "Male",
:first_name => "foo",
:last_name => "bar"
}
}
credentials = default.merge(opts)
provider = credentials[:provider]
user_hash = credentials[provider]
OmniAuth.config.test_mode = true
OmniAuth.config.mock_auth[provider] = {
'uid' => credentials[:uuid],
"extra" => {
"user_hash" => {
"email" => user_hash[:email],
"first_name" => user_hash[:first_name],
"last_name" => user_hash[:last_name],
"gender" => user_hash[:gender]
}
}
}
end
def set_invalid_omniauth(opts = {})
credentials = { :provider => :facebook,
:invalid => :invalid_crendentials
}.merge(opts)
OmniAuth.config.test_mode = true
OmniAuth.config.mock_auth[credentials[:provider]] = credentials[:invalid]
end
With this sweet setup, I can now have multiple defaults in my tests, which makes changes very clean:
background do
set_omniauth()
click_link_or_button 'Sign up with Facebook'
end
Happy Hacking
