我正在嘗試使用minitest來測試我的應用程序類,但我收到一條錯誤消息,指出undefined method image_path
。我怎樣才能解決這個問題?在minitest中使用幫助程序
app_test.rb
require 'test_helper'
class AppTest < ActiveSupport::TestCase
setup do
@app = apps(:app_one)
end
test 'should have icon_url' do
assert(@app.icon_url == image_path('icn-medium-norm.png'))
end
end
應用程序/模型/ app.rb
class App < ActiveRecord::Base
has_many :versions, dependent: :destroy
has_many :user_subscriptions, dependent: :destroy
has_many :users, through: :user_subscriptions
validates :name, uniqueness: { case_sensitive: false, scope: :app_type }
scope :since, ->(time) { where('created_at > ?', time) }
scope :ios, -> { where("app_type = 'ios' ") }
scope :android, -> { where("app_type = 'android' ") }
def icon_url
versions.last[:icon_url] || image_path('icn-medium-norm.png')
end
...
end
甚至當我這樣做
test 'should have icon_url' do
assert(@app.icon_url =~ %r{.png})
end
我得到的,因爲應用程序的同樣的錯誤模型
看看[這裏](http://guides.rubyonrails.org/testing.html#integration-testing),如果有幫助.. – 2015-04-03 17:52:51
