'未定義的本地變量或方法'用於期望導出到助手的方法

Question

目標：嘗試提交空的註冊表單由於驗證錯誤而失敗。期望在場景中呈現爲單線（方法）。錯誤正在根據其位置進行非常精確的檢查。我不想使用經典計數，直到剩下唯一的方法。

def cant_be_blank_error_is_displayed(number_of_times = 1) 
    expect(page).to have_content t('errors.messages.blank'), count: number_of_times 
end 

---

require 'rails_helper' 
require 'email_helper' 

feature 'register organisation', type: :feature, js: true do 
    let!(:register_page) { RegisterPage.new } 
    let!(:login_page) { LoginPage.new } 
    let!(:organisation) { create :organisation, name: 'organisation_name' } 
    let!(:owner) { create :user, email: 'user@example.com', role: :owner } 
    let(:form) { register_page.register_form } 

    before { register_page.load } 

    context 'creation fails because' do 
    scenario 'mandatory fields were left empty' do 
     register_page.submit_empty_form 
     all_mandatory_fields_cant_be_blank_error_displayed 
    # expect(form).to have_content mail_blank_or_taken_error 
    end 

    scenario (...) 
    end 
    end 

方法：
1.定義在頁面的特定錯誤作爲元素

class RegisterPage < SitePrism::Page 
    set_url "/sign_up" 
    section :register_form, :xpath, "//*[@id='new_user']" do 
    element :email, :xpath, "//*[@id='user_email']" 
    (...) # other input fields 

# binding.pry confirms they appear on the page 
    element :mail_blank_or_taken_error, :xpath, "//*[@id='new_user']/div[2]/span" 
    element :blank_password_error, :xpath, "//*[@id='new_user']/div[4]/span" 
    element :password_too_short_error, :xpath, "//*[@id='new_user']/div[2]/div[3]/p" 
    element :mismatch_error, :xpath, "//*[@id='new_user']/div[2]/div[4]/span" 
    element :blank_name_error, :xpath, "//*[@id='new_user']/div[2]/div[5]/span" 
    element :name_taken_error, :xpath, "//*[@id='new_user']/div[2]/div[5]" 
    element :wrong_format_error, :xpath, "//*[@id='new_user']/div[7]/span 
    (...) 
    end 
end 

2.創建error_alerts.rb輔助存儲在一個方法期望

def all_mandatory_fields_cant_be_blank_error_displayed 
    [ 
    mail_blank_or_taken_error, 
    blank_password_error, 
    signs_limit_error, 
    blank_name_error, 
    blank_adress_line_error, 
    blank_city_error, 
    blank_country_error, 
    blank_zipcode_error, 
    blank_phone_number_error, 
    blank_website_error, 
    ].each do |validation_errors| 
    expect(form).to have_content validation_errors 
    end 
end 

障礙： 錯誤是默認的軌道的，所以他們都沒有定義爲翻譯，我在另一個規範使用相同的約定，一切都準確無誤地運行。

例如：

def invalid_email_or_password_error_displayed 
    expect(login_page).to have_content t("devise.failure.invalid", authentication_keys: "Email") 
end 

失敗：我收到以下錯誤。

1＃我的方式 - 同樣的問題發生從|validation_errors|

1) register organisation creation fails because mandatory fields were left empty 
    Failure/Error: mail_blank_or_taken_error, 

    NameError: 
     undefined local variable or method `mail_blank_or_taken_error' for #<RSpec::ExampleGroups::RegisterOrganisation::CreationFailsBecause:0x007fe56b336370> 
# ./spec/support/error_alerts.rb:63:in `all_mandatory_fields_cant_be_blank_error_displayed' 
# ./spec/features/organisation_registration_spec.rb:16:in `block (3 levels) in <top (required)>' 

2＃經典每個對象預計

1) register organisation creation fails because mandatory fields were left empty 
    Failure/Error: expect(form).to have_content 
mail_blank_or_taken_error 

    NameError: 
     undefined local variable or method `mail_blank_or_taken_error' for # <RSpec::ExampleGroups::RegisterOrganisation: :CreationFailsBecause:0x007ff02e7b9348>#./spec/features/organisation_registration_spec.rb:17:in `block (3 levels) in <top (required)>' 

問：是我的方式進行一些修改或之後技術上是可以實現唯一的解決辦法是使用經典的計數方法？循環可以迭代頁面的元素嗎？這是一個類似使用的例子，雖然期望是字符串，循環本身包含在spec的場景中，而不是在助手中被導出到外部方法。

scenario "is successful" do 
     all_ministry_memberships_page.create_new(ministry, cabinet, minister) 
     [ 
     t("flash.actions.create.notice", resource_name: "Ministry membership"), 
     "Ministry " + ministry.name, 
     "Cabinet " + cabinet.name, 
     "Minister " + minister.name, 
     "Start Date " + (cabinet.appointment_date + 2.days).strftime("%Y-%m-%d"), 
     "Created At " + ministry_membership.created_at.strftime("%B %0e, %Y %H:%M"), 
     "Updated At " + ministry_membership.updated_at.strftime("%B %0e, %Y %H:%M"), 
     ].each do |form_input| 
     expect(form).to have_content form_input 
     end 
    end 

Answer 1

這

[ 
    mail_blank_or_taken_error, 
    blank_password_error, 
] 

意味着 「調用方法mail_blank_or_taken_error()，然後blank_password_error()並把他們的結果在一個數組」。你沒有這種方法，這就是錯誤信息告訴你的。如果你想要那些字符串，讓他們成爲字符串。

[ 
    "mail_blank_or_taken_error", 
    "blank_password_error", 
] 

或

%w[ 
    mail_blank_or_taken_error 
    blank_password_error 
] 

Answer 2

我發現解決這個問題。

的方法需要適當的參數解析和page_object參考

def all_mandatory_fields_cant_be_blank_error_displayed_in(form) 
    [ 
    form.blank_password_error, 
    form.signs_limit_error, 
    form.blank_name_error, 
    form.blank_adress_line_error, 
    form.blank_city_error, 
    form.blank_country_error, 
    form.blank_zipcode_error, 
    form.blank_phone_number_error, 
    form.blank_website_error, 
    ].each do |validation_error| 
    expect(validation_error).to be_present 
    end 
end
