Deprecated as of September 19, 2024

fake_stripe has been deprecated in favor of stripe-ruby-mock.

fake_stripe, a Stripe fake

This library is a way to test Stripe code without hitting Stripe's servers. It uses Capybara::Server and Webmock to intercept all of the calls from Stripe's Ruby library and returns JSON that the Stripe library can parse.

Installation

Gemfile

Add the fake_stripe Gem to the :test group in your Gemfile:

# Gemfile
group :test do
  gem 'fake_stripe'
end

Remember to run bundle install.

Stripe settings

Set the STRIPE_JS_HOST constant in an initializer:

# config/initializers/stripe.rb
Stripe.api_key = ENV['STRIPE_API_KEY']

unless defined? STRIPE_JS_HOST
  STRIPE_JS_HOST = 'https://js.stripe.com'
end

Include the Stripe JavaScript in your application template.

For Stripe.js v1:

# app/views/layouts/application.html.erb
<%= javascript_include_tag "#{STRIPE_JS_HOST}/v1/" %>

For Stripe.js v2:

# app/views/layouts/application.html.erb
<%= javascript_include_tag "#{STRIPE_JS_HOST}/v2/" %>

For Stripe.js v3:

# app/views/layouts/application.html.erb
<%= javascript_include_tag "#{STRIPE_JS_HOST}/v3/" %>

When the test suite runs fake_stripe will override the address for STRIPE_JS_HOST and serve up a local version of Stripe.js.

In Tests

Require the library in your spec support:

# spec/support/fake_stripe.rb
require 'fake_stripe'

RSpec.configure do |config|
  config.before(:each) do
    FakeStripe.stub_stripe
  end
end
