Rails控制器rspecs在規範/控制器中失敗，並且通過了RoutingError，但通過了單個測試

Question

當我將它們作爲控制器一起運行時，我的控制器規格在我逐一運行時傳遞，但都失敗。

$rspec spec/controllers 

22) SubjectsController GET index assigns all subjects as @subjects 
    Failure/Error: get :index, {} 
    ActionController::RoutingError: 
     No route matches {:controller=>"subjects"} 
    # ./spec/controllers/subjects_controller_spec.rb:13:in `block (3 levels) in <top (required)>' 

我的猜測是它必須與數據庫清理有關，但我不確定解決控制器規格中路由錯誤的最佳方法。

Answer 1

了它。

的的ActionController :: RoutingError是另一個控制器規範的結果是在呼喚：

routes.draw 

這一呼籲消滅後續規格的路由。對於現在的解決方案（以感謝：

http://pivotallabs.com/adding-routes-for-tests-specs-with-rails-3/）是添加：

after do 

    # be sure to reload routes after the tests run, otherwise all your 
    # other controller specs will fail 
    Rails.application.reload_routes! 

end 

也有利於爲：

希望這有助於和好運！
