rspec時出現 undefined method

昨天一直出現下面的錯誤

Failures:

1) PagesController :index home path

Failure/Error: visit '/pages/home'

NoMethodError:

undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1:0xbabf1d4>

# ./spec/controllers/pages_controller_spec.rb:17:in `block (3 levels) in <top (required)>'

...

 

在stackoverflow上面找到了答案,其實是需要一個simulated browser,解決辦法:

1.在Gemfile中添加 gem 'capybara'

2.bundle install

3.在spec_helper中添加 require 'capybara/rspec'

 

如果有其它問題,可以參見rspec的文檔:
