Rails - execute task before server starts

I want my app to execute a task (download CSV files from another website & parse them) just before the server starts.

In which file exactly should I put the code for this?(maybe db/seeds.rb?)

Also, any idea on how to test this with RSpec?

Inside initializers folder, can create any .rb file and can write any logical code in that file. It will be executed on start.

But it may slow down server start, because in your case csv download and parsing may take time to execute.

One solution, this may be not right

in lib/tasks/say_hello_rake.rake

namespace :sample do
  task :your_task_name do
    puts 'Hello my task ... '
  end
end

before rails s

rake sample:your_task_name

From the Rails Guides:

In the rare event that your application needs to run some code before Rails itself is loaded, put it above the call to require 'rails/all' in config/application.rb.

The initializers folder is the proper place to set this tasks.

Just create a file with .rb extension, and everything else will be performed on start.
