ruby - Minitest:如何测试方法

Question

我正在尝试在我的代码中测试该方法，但第二个测试返回错误 undefined local variable or method 'params'

测试方法的正确方法是什么？还是我需要对 main.rb 的设置方式进行更改？

代码:

require 'sinatra'
require 'sinatra/reloader'


def get_products_of_all_ints_except_at_index()
  @array = [1, 7, 3, 4]
  @total = 1
  @index = params[:index].to_i
  @array.delete_at(@index)
  @array.each do |i|
    @total *= i
  end
end



get '/' do
  get_products_of_all_ints_except_at_index
  erb :home
end

测试:

ENV['RACK_ENV'] = 'test'

require 'minitest/autorun'
require 'rack/test'

require_relative 'main.rb'

include Rack::Test::Methods

def app
  Sinatra::Application
end

describe 'app' do
  it 'should return something' do
    get '/'
    assert_equal(200, last_response.status)
  end

  it 'should return correct result' do
    get_products_of_all_ints_except_at_index
    assert_equal(24, @total)
  end
end

您没有通过 get 请求传递任何参数，请尝试:

get '/', :index => '1'
