testing stripe with stripe.js in rails 3 - ruby-on-rails

Question

My app uses the stripe.js java library to generate the stripe_card_token same as ryan bates did here.
I'm trying to add unit tests to my controller and I'm getting troubles in the generation of the token. I couldn't find the function to generate the token anywhere in the Stripe API, as it seems to be available only in the javascript.
How can I generate the stripe_token in the test?
Here's the part of the controller dealing with stripe:
def save_with_payment!
if valid?
customer = Stripe::Customer.create(
description: "#{user.email} - #{user.id} - #{billing_name}",
email: billing_email,
plan: plan,
card: stripe_card_token)
self.stripe_customer_token = customer.id
plan = validate_actual_plan customer.subscriptions.data[0].plan.id
save!
end
rescue Stripe::InvalidRequestError => e
logger.error "Stripe error while creating customer: #{e.message}"
errors.add :base, "There was a problem with your credit card.
Your card wasn't charged. #{e.message}"
return false
end
Here's the controller:
def create
#subscription = Subscription.new(params[:subscription])
#subscription.user_id = current_user.id
#subscription.expiration_date = 1.month.from_now
#subscription.stripe_card_token = params[:subscription][:stripe_card_token]
respond_to do |format|
if #subscription.save_with_payment!
if current_user.upgrade_plan :premium
format.html { redirect_to user_trades_path(current_user), notice: 'Subscription was successfully created. Compliments you are now subscribed to the premium plan' }
format.json { render json: user_trades_path(current_user), status: :created, location: #subscription }
else
format.html { redirect_to home_pricing_path, notice: 'Error while upgrading your account, please contact us' }
format.json { render json: home_pricing_path, status: :created, location: #subscription }
end
else
format.html { render action: "new" }
format.json { render json: #subscription.errors, status: :unprocessable_entity }
end
end
end
This is the Coffeescript generating the token:
processCard: ->
card =
number: $(page.cardNumber).val()
cvc: $(page.cardCode).val()
expMonth: $(page.cardMonth).val()
expYear: $(page.cardYear).val()
Stripe.card.createToken(card, #handleStripeResponse)
Here's the test:
test "should create subscription" do
begin
StripeMock.start
card = {
number: "4242424242424242",
cvc: "123",
expMonth: 1.month.from_now.month,
expYear: 1.year.from_now.year,
}
token = Stripe.card.createToken(card)
assert_difference('Subscription.count') do
post :create, subscription: {
billing_email: #subscription.billing_email,
billing_city: #subscription.billing_city,
billing_country: #subscription.billing_country,
billing_name: #subscription.billing_name,
billing_street2: #subscription.billing_street2,
billing_street: #subscription.billing_street,
billing_zip: #subscription.billing_zip,
stripe_card_token: token,
plan: #subscription.plan }
end
assert_redirected_to subscription_path(assigns(:subscription))
ensure
StripeMock.stop
end
end

I figured that creating the token was indeed possible with the Stripe API, as described here:
https://stripe.com/docs/api#create_card_token
I had also found an issue with the plan I was going to subscribe, because I'm using StripeMock, there's no connection to the real/test stripe at all. this means that my mock doesn't know about the plans I try to subscribe.
I had to generate a little function to generate the plan as well.
here's its code:
def create_plan
plan = {
:amount => 1800,
:interval => 'month',
:name => 'premium',
:currency => 'gbp',
:id => 'premium'
}
response = Stripe::Plan.create plan
end
