我有带有黄瓜功能的Rails 4应用程序。在一些测试中，我有思考sphinx数据，如：
@javascript @sphinx
Feature: Edit a service
Scenario: Editing
Given I exist as an "individual"
And I have few services as individual user
And Sphinx indexes all models
...
Then I should see I18n translation for key "views.messages.notices.add.updated"
@sphinx hook包含此逻辑：
Before('@sphinx') do
self.use_transactional_fixtures = false
ThinkingSphinx::Test.start
sleep 2 # Give some time for sphinx to start.
end
After('@sphinx') do
ThinkingSphinx::Test.stop
self.use_transactional_fixtures = true
end
Sphinx indexes all models包含此内容：
Given(/^Sphinx indexes all models$/) do
ThinkingSphinx::Test.index
# Wait for Sphinx to finish loading in the new index files.
sleep 0.25 until index_finished?
end
以下是database.yml：
development:
adapter: postgresql
database: my-project_development
host: localhost
encoding: UTF8
pool: 5
test: &test
adapter: postgresql
database: my-project_test<%= ENV['TEST_ENV_NUMBER'] %>
username: my-project
password: my-project
host: localhost
encoding: UTF8
pool: 15
当我通过rake parallel:features（通过parallel_tests）规范运行我的规范时思考sphinx总是失败：
Can't connect to MySQL server on '127.0.0.1' (61) (ThinkingSphinx::ConnectionError)

但是如果我在非并行模式下运行这些失败的测试（我的意思是cucumber path/to/my/test.rb），它就可以工作（是的，parallel_tests适用于其他测试）。我该如何解决这个问题？
答案 0 :(得分：1)
您希望将config/thinking_sphinx.yml配置为在Sphinx文件的路径中包含该环境变量TEST_ENV_NUMBER - 文档的deployment page中列出的设置应为＆＃ 39; s required，以及端口号（mysql41设置）。也许是这样的？
test:
mysql41: <%= ENV['TEST_ENV_NUMBER'].to_i + 9307 %>
pid_file: /path/to/app/tmp/searchd.<%= ENV['TEST_ENV_NUMBER' %>.pid
indices_location: /path/to/app/db/sphinx/<%= ENV['TEST_ENV_NUMBER' %>
configuration_file: /path/to/app/config/test.<%= ENV['TEST_ENV_NUMBER' %>.sphinx.conf
binlog_path: /path/to/app/db/sphinx/<%= ENV['TEST_ENV_NUMBER' %>/binlog
我自己没有使用过这种方法（或parallel_test），所以这肯定是猜测，但值得一试。
