RSpec的3 RuntimeError： 「我們申報的'前訪問（：上下文）`掛鉤」

Question

這是我的錯誤

Failure/Error: @queue = FactoryGirl.create(model.to_s.underscore.to_sym) 
RuntimeError: 
    let declaration `model` accessed in a `before(:context)` hook at: 
    /var/www/html/SQ-UI/spec/support/user_queue/asterisk_serialize_spec.rb:7:in `block (2 levels) in <top (required)>' 

    `let` and `subject` declarations are not intended to be called 
    in a `before(:context)` hook, as they exist to define state that 
    is reset between each example, while `before(:context)` exists to 
    define state that is shared across examples in an example group.enter code here 

和這裏是它打破

let(:model) { described_class } # the class that includes the concern 

before(:all) do 
    @queue = FactoryGirl.create(model.to_s.underscore.to_sym) 
end 

我的代碼我試圖將它們移除並移動它們但沒有成功。

Answer 1

您不能在before(:all)/before(:context)鉤子中引用let變量（或subject）。這樣做是在2 RSpec的否定並取消從RSpec的3

在你的情況下，它看起來像你可以只內聯let可變進before(:all)塊：

before(:all) do 
    @queue = FactoryGirl.create(described_class.to_s.underscore.to_sym) 
end
