Rails 4：如何测试控制器动作

Question

How do I actually test this Controller Action, I wrote in my PurchasesController:

protect_from_forgery except: [:hook]
def hook
    params.permit! # Permit all Paypal input params
    status = params[:payment_status]
    if status == "Completed"
        @purchase = Purchase.find(params[:invoice])
        @purchase.update_attributes(status: status, transaction_id: params[:txn_id], purchased_at: Time.now)
        @purchase.save!
        @user = @tool.user
        @user.earned_money += @tool.price
        @user.save!
    end
    render nothing: true
end

preferably with my Rails Console?

Routes:

post "/purchases/:id" => "purchases#show"
post "/hook" => "purchases#hook"

Answer 1

You don't test controllers through the rails console.

Controllers in Rails respond to HTTP requests - they are instantiated by the routing component when it matches an incoming request. So you would test controllers by sending a HTTP request and inspecting the response.

You can manually test your controller by using the command line tool cURL or the browser based Postman to send a request*. You can the use the rails console to check for side effects such as changes in the database.

However, you should consider using an automated testing tool such as Minitest or RSpec as manually testing your application is a flawed approach.

Answer 2

I'm not totally sure you can test this through your console, unless you decouple/abstract the other operations being performed and then you test the units independently. With RSpec/Minitest, though you just have to create the records and do a post request to the /hook route, passing the expected params: invoice , txn_id , payment_status .

Let me know if that helps.
