How to implement Retry on RSPEC Please?

Question

I would like to implement a retry for a number of times if the server is unavailable at that time!. Is possible?.

require 'httparty'
require 'pry'
require_relative '../../env.rb'

RSpec.describe 'Validar a api de usuários' do

  it 'Deve retornar 200 para API DRIVE THRU' do
    response = HttParty.get("#{URLS['drive_thru']}/v1/health/live")
    expect(response.code).to eql(200)
    expect(response.parsed_response).to be_nil
  end
end

It would be the same way you'd retry in regular code. E.g. a loop with a rescue or conditional. What is the error case you want to retry on? — max pleaner, Nov 03 '20 at 18:47
Hello my friend, I honestly don't know how to do it. I want that if the api fails to run for 3X and if the server is unavailable it will present the message: "Server unavailable" — Silvio Aulik, Nov 03 '20 at 19:08
But the specific details matter. What exactly happens right now when the server is unavailable? Do you get a SocketError raised? Or just a different response code? — max pleaner, Nov 03 '20 at 21:34

A general purpose retry system might look like this:

tries_left = 3
loop do
  break if tries_left == 0
  begin
    result = do_thing
  rescue SomeError => e
    tries_left -= 1
  end
end

You have to replace do_thing and SomeError with your HTTParty call and whatever error is being raised.
