[Note] Rails 升級 4.2 後 assert_select 錯誤

升級 rails 後，執行 rspec。跳出了這個錯誤 NameError: uninitialized constant ActionDispatch::Assertions::SelectorAssertions 原因: ActionDispatch::Assertions::SelectorAssertions 在 4.2 版移至 ::Rails::Dom::Testing::Assertions::SelectorAssertions Ref: -fix for Rails »

[Note] Upgrade Ralis to 4.2.9

bundle update rails responders 兩個要一起更新，不然會發生錯誤 Bundler could not find compatible versions for gem "actionpack": In Gemfile: rails (~> 4.1.14) was resolved to 4.1.15, which depends on actionpack (= 4.1.15) responders (= 2.4.0) was resolved »
