由于database_cleaner故障导致Rails capybara测试失败

Question

我已经安装了database_cleaner并且对我的所有测试都有效，除非它遇到这个......

scenario "is coach, signs up, email not in const, requests admin status" do
  user_sign_in(user1)
  visit my_profile_users_path
  click_button "Request Admin Status"

  expect(ActionMailer::Base.deliveries.count).to eq(1)
end

Rails返回     失败/错误：期望（ActionMailer :: Base.deliveries.count）.to eq（1）        预期：1             得到：137        （使用==进行比较）

不确定为什么数据库清理程序在这个实例上失败或如何修复它。任何帮助，将不胜感激。

Gemfile.rb

group :test do
  gem 'coveralls', require: false
  gem 'database_cleaner'
  gem 'launchy', require: false
end

规格/支持/ database_cleaner.rb

# frozen_string_literal: true

RSpec.configure do |config|

  config.before(:each) do
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each) do
    DatabaseCleaner.strategy = :truncation
  end

  config.before(:each, js: true) do
    DatabaseCleaner.strategy = :truncation
  end

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end

  config.after(:each) do
  end
end

rails_helper.rb

require 'spec_helper'
require 'rspec/rails'
require_relative "../spec/support/database_cleaner"

spec_helper.rb

require 'database_cleaner'

我相信我通过改变测试来解决这个问题。

scenario "is coach, signs up, email not in const, requests admin status" do
  user_sign_in(user1)
  visit my_profile_users_path
  click_button "Request Admin Status"

  expect(ActionMailer::Base.deliveries.last.subject).to have_content("#{user1.username} requested admin")
end
