本文介绍了一种测试Rails应用中Helper方法的方法。通过在测试文件中引入特定的类，并使用include关键字来包含Helper模块，可以实现对Helper方法的有效测试。
今天我们看看怎么测试我们的helper方法:
[code]
require File.dirname(__FILE__) + '/../test_helper'
class HelperTest < Test::Unit::TestCase
include ActionView::Helpers::UrlHelper
include ActionView::Helpers::TextHelper
include ActionView::Helpers::TagHelper
include ApplicationHelper
# include whatever helpers you want to test here, sometimes you'll need
# to include some of the Rails helpers, as I've done above.
def test_some_helper
end
end
[/code]
通过include ApplicationHelper，则该类里面定义的所有方法都可以作为本地方法得到
如果想测试其它类里面的helper方法，我们只需要将该类include即可
[code]
require File.dirname(__FILE__) + '/../test_helper'
class HelperTest < Test::Unit::TestCase
include ActionView::Helpers::UrlHelper
include ActionView::Helpers::TextHelper
include ActionView::Helpers::TagHelper
include ApplicationHelper
# include whatever helpers you want to test here, sometimes you'll need
# to include some of the Rails helpers, as I've done above.
def test_some_helper
end
end
[/code]
