在测试环境中启动轨道

Question

我正在尝试使用ruby脚本在测试环境中加载rails.我试过谷歌搜索,发现这个建议:

require "../../config/environment"
ENV['RAILS_ENV'] = ARGV.first || ENV['RAILS_ENV'] || 'test'

这似乎加载了我的环境,但我的开发数据库仍在使用中.难道我做错了什么？

这是我的database.yml文件...但我不认为这是问题

development:
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: BrianSite_development
  pool: 5
  username: root
  password: dev
  host: localhost

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: BrianSite_test
  pool: 5
  username: root
  password: dev
  host: localhost

production:
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: BrianSite_production
  pool: 5
  username: root
  password: dev
  host: localhost

我不能用

ruby script/server -e test

因为我在加载rails后试图运行ruby代码.更具体地说,我要做的是:运行.sql数据库脚本,加载rails然后运行自动化测试.一切似乎都运行良好,但无论出于何种原因,rails似乎在开发环境而不是测试环境中加载.

这是我试图运行的代码的缩短版本:

system "execute mysql script here"

require "../../config/environment"
ENV['RAILS_ENV'] = ARGV.first || ENV['RAILS_ENV'] || 'test'

describe Blog do
  it "should be initialized successfully" do
    blog = Blog.new
  end
end

我不需要启动服务器,我只需要加载我的rails代码库(模型,控制器等),这样我就可以对我的代码运行测试了.

谢谢你的帮助.

更新:

我现在正在加载我的rails环境.现在我正在尝试在我的rake任务中运行我的测试文件.这是我的代码:

require"spec"
require "spec/rake/spectask"
RAILS_ENV = 'test'

namespace :run_all_tests do
  desc "Run all of your tests"

  puts "Reseting test database..."
  system "mysql --user=root --password=dev < C:\\Brian\\Work\\Personal\\BrianSite\\database\\BrianSite_test_CreateScript.sql"
  puts "Filling database tables with test data..."
  system "mysql --user=root --password=dev < C:\\Brian\\Work\\Personal\\BrianSite\\database\\Fill_Test_Tables.sql"

  puts "Starting rails test environment..."
  task :run => :environment do
    puts "RAILS_ENV is #{RAILS_ENV}"
    require "spec/models/blog_spec.rb"
  end
end

我认为要求"spec/models/blog_spec.rb"文件会这样做,但它似乎没有运行测试......

感谢迄今为止的帮助.

Answer 1

这个命令为我做了.我能够用它的数据库加载测试env aloong.

$rails s -e test

Answer 2

要启动测试环境,您应该使用-eparam 运行脚本/服务器:

ruby script/server -e test

并且在你的config/database.yml中必须是测试env数据库的defenition,即:

test:
  adapter: sqlite3
  database: db/test.sqlite3
  pool: 5
  timeout: 5000

Answer 3

你知道你可以运行Rake的单元,功能和集成测试,对吗？查看输出,rake -T test看看如何.

如果您需要更多自定义内容,您可以创建自己的Rake任务.把这样的东西放在一个文件中lib/tasks:

namespace :custom_tests do
  desc "Run my custom tests"
  task :run => :environment do
    puts "RAILS_ENV is #{RAILS_ENV}"
    system "execute mysql script here"
    # Do whatever you need to do
  end
end

该=> :environment载荷为你当前的环境.然后,您可以在测试环境中运行您的任务,如下所示:RAILS_ENV=test rake custom_tests:run
