在Heroku上测试缓慢

Question

我可以理解这个问题很笼统，但是我遇到的一个问题是，我在Heroku上进行的测试非常慢（超过20分钟），而在本地运行它们大约需要9或10分钟。我想知道我是否可以针对这个问题指明正确的方向。这是我的rails_helper.rb：

require 'simplecov'
SimpleCov.start
# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)

# Prevent database truncation if the environment is production
abort("The Rails environment is running in production mode!") if Rails.env.production?

require 'spec_helper'
require 'rspec/rails'
require 'shoulda/matchers'

require 'sidekiq/testing'
Sidekiq::Testing.fake!

require 'public_activity/testing'
PublicActivity.enabled = false

# Checks for pending migrations before tests are run.
ActiveRecord::Migration.maintain_test_schema!

require 'capybara/rspec'


Capybara.asset_host = ENV['CAPYBARA_ASSET_HOST'] || "http://localhost:#{ENV.fetch('PORT', 3000)}"
Capybara.register_driver :headless_chrome do |app|
  chrome_bin = ENV.fetch('GOOGLE_CHROME_SHIM', nil)
  chrome_opts = chrome_bin ? { 'binary': chrome_bin } : {}
  capabilities = Selenium::WebDriver::Remote::Capabilities.chrome chromeOptions: { args: %w[headless disable-gpu disable-dev-shm-usage no-sandbox] }.merge(chrome_opts)
  Capybara::Selenium::Driver.new app, browser: :chrome, desired_capabilities: capabilities
end
Capybara.javascript_driver = :headless_chrome
Capybara.server = :puma, { Silent: true }

# NOTE: Running with sauce REQUIRES SAUCE CONNECT tunnel driver
# so that saucelabs instance can communicate with your test server.
# run with...

#   caps = Selenium::WebDriver::Remote::Capabilities.chrome()
#   caps['platform'] = 'macOS 10.12'
#   caps['version'] = '52.0'
#   sauce_endpoint = "http://obiefernandez:24e2ec72-ff16-4526-9a35-d7e8bd180d5a@ondemand.saucelabs.com:80/wd/hub"
#   Capybara::Selenium::Driver.new app, :browser => :remote, :url => sauce_endpoint, :desired_capabilities => caps
