我运行Cucumber和RSpec测试的rake任务总是使用我的development环境。

# per-scenario basis by tagging a scenario or feature with the @allow-rescue tag.
#
# If you set this to true, Rails will rescue all errors and render error
# pages, more or less in the same way your application would behave in the
# default production environment. It's not recommended to do this for all
# of your scenarios, as this makes it hard to discover errors in your application.
ActionController::Base.allow_rescue = false
# If you set this to true, each scenario will run in a database transaction.
# You can still turn off transactions on a per-scenario basis, simply tagging

# tagging with @culerity or @javascript will also turn transactions off.
#
# If you set this to false, transactions will be off for all scenarios,
# regardless of whether you use @no-txn or not.
#
# Beware that turning transactions off will leave data in your database
# after each scenario, which can lead to hard-to-debug failures in
# subsequent scenarios. If you do this, we recommend you create a Before
# block that will explicitly put your database in a known state.

#
# You can declare fixtures for each example_group like this:
# describe "...." do
# fixtures :table_a, :table_b
#
# Alternatively, if you prefer to declare them only once, you can
# do so right here. Just uncomment the next line and replace the fixture
# names with your fixtures.
#
# config.global_fixtures = :table_a, :table_b
#
# If you declare global fixtures, be aware that they will be declared
# for all of your examples, even those that don't use them.
#
# You can also declare which fixtures to use (for example fixtures for test/fixtures):
#
# config.fixture_path = RAILS_ROOT + '/spec/fixtures/'
#
# == Mock Framework
#
# RSpec uses its own mocking framework by default. If you prefer to
# use mocha, flexmock or RR, uncomment the appropriate line:
#
# config.mock_with :mocha
# config.mock_with :flexmock
# config.mock_with :rr
#
# == Notes
#
# For more information take a look at Spec::Runner::Configuration and Spec::Runner

在RAILS_ROOT / Gemfile
上做的： 将特定的仅测试宝石添加到该组：
group :test do
gem 'cucumber-rails'
gem 'capybara'
gem 'database_cleaner'
end
而不是将它们设置为在开发和其他任何地方使用。 这应该有用。
P.S：编辑上面的代码来设置你将用于测试的宝石，我只是复制/粘贴我在目前打开的项目中使用的那些。作为一个例子。

当您升级到Rails 3时，您是否可以在RAILS_ENV上进行全局查找和替换？
test_helper.rb的第一行是否不是这个？
ENV [“RAILS_ENV”] =“测试”
在实际的环境变量中，它应该仍然是RAILS_ENV，而不是:: Rails.env，所以请确保您没有针对该行代码的ENV [“Rails.env”] =“test”。
确保它看起来像以前一样。不是因为我个人犯了这个错误而知道......： - ）
答案 2 :(得分：1)
配置文件不仅与设置rails环境有关。
检查您的lib/tasks/cucumber.rake文件，如果它不包含，请根据您的rails版本添加以下行之一（我在'begin'行后添加）：
ENV["RAILS_ENV"] ||= 'cucumber' #for rails2
Rails.env ||= ActiveSupport::StringInquirer.new('cucumber') #for rails3
请注意，例如，如果您直接在application.rb中将环境设置为开发，那么您的测试将在开发中运行。
还有另一种方法可以将环境设置为黄瓜。例如，如果你使用Passenger和Apache运行rails，那么可以通过在虚拟主机配置中添加"RailsEnv cucumber"行来在黄瓜环境中运行黄瓜测试。
