RSpec的自定義驗證

Question

我在鐵軌模型的定製驗證：

validate :custom_validation_method 

def custom_validation_method 
    # do stuff here 
end 

我怎樣才能讓RSpec的這個？謝謝！

Answer 1

爲了測試驗證（任意）

describe MyClass do 
    it '#custom_validation' do 
    expect(subject.valid?).to be_falsey 
    #do stuff to subject to make it valid 
    expect(subject.valid?).to be_truthy 
    end 
end
