未定義的方法``有效的 「possimus」：字符串

Question

測試代碼：

context 'validations' do 
let(:super_campaign){FactoryGirl.create(:super_campaign)} 
    context 'package' do 
    it "Package should be present" do 
    expect(super_campaign.package).to be_valid 
    end 
    end 
end 

我收到錯誤，如undefined method "valid?" for "possimus":String

Answer 1

只能測試，整個模型是有效的。不過，您可以測試package屬性是否有錯誤。

context 'validations' do 
let(:super_campaign){FactoryGirl.create(:super_campaign)} 
    context 'package' do 
    it "Package should be present" do 
    expect(super_campaign).to be_valid 
    expect(super_campaign.errors[:package]).to be_nil 
    end 
    end 
end 

Answer 2

expect(super_campaign).to be_valid # AR object, not it's attribute
