else
# Wrong signature!
end

Tests

To pass the API tests, specify API keys in ENV['LIQPAY_PUBLIC_KEY'] and ENV['LIQPAY_PRIVATE_KEY'] or in spec/dummy/config.rb:

# spec/dummy/config.rb
::Liqpay.configure do |config|
  config.public_key = 'public_key'
  config.private_key = 'private_key'
end

To run local only tests(keys are not required), execute

rspec --tag ~@real

With real api test you can specify email to recive invoce from Liqpay:

LIQPAY_PUBLIC_KEY=real_public_key LIQPAY_PRIVATE_KEY=real_private_key TEST_EMAIL=real_email rspec --tag @real
