Rails4：減少Rspec和Capybara錯誤輸出

Question

有沒有辦法禁用Rspce＆Capybara的錯誤輸出？ 我只想看看主要錯誤

   Delete an Article User Delete an Article
             Failure/Error: click_link "Delete Article"
             ActiveRecord::RecordNotFound:
               Couldn't find Article with 'id'=315

而不是完整的錯誤日志。

 Delete an Article User Delete an Article
         Failure/Error: click_link "Delete Article"
         ActiveRecord::RecordNotFound:
           Couldn't find Article with 'id'=315
         # /usr/local/rvm/gems/ruby-2.2.2/gems/activerecord-4.2.1/lib/active_record/core.rb:155:in `find'
         # ./app/controllers/articles_controller.rb:29:in `show'
         # /usr/local/rvm/gems/ruby-2.2.2/gems/actionpack-4.2.1/lib/action_controller/metal/implicit_render.rb:4:in `send_action'

         # /usr/local/rvm/gems/ruby-2.2.2/gems/activesupport-4.2.1/lib/active_support/callbacks.rb:117:in `call'
         # /usr/local/rvm/gems/ruby-2.2.2/gems/activesupport-4.2.1/lib/active_support/callbacks.rb:117:in `call'
         # /usr/local/rvm/gems/ruby-2.2.2/gems/activesupport-4.2.1/lib/active_support/callbacks.rb:555:in `block (2 levels) in compile'
        ....

我的寶石文件

group :development, :test do
  gem 'byebug'
  gem 'rspec-rails','3.2.3'
  gem 'guard-rspec',require: false
  gem 'spring-commands-rspec'
  gem 'web-console', '~> 2.0'
  gem 'spring'
end

group :test do

  gem 'capybara','2.4.4'

end

我想禁用它，因為我需要滾動很多才能看到真正的錯誤。 希望清楚。

Answer 1

我剛剛嘗試過，它在Rspec 3.4.0中可以正常工作，它阻止了延伸到gems中的回溯：

# spec_helper.rb
RSpec.configure do |config|
  config.backtrace_exclusion_patterns = [
    /\/lib\d*\/ruby\//,
    /bin\//,
    /gems/,
    /spec\/spec_helper\.rb/,
    /lib\/rspec\/(core|expectations|matchers|mocks)/
  ]
end

確保您使用的是config.backtrace_exclusion_patterns而不是config.backtrace_clean_patterns因為您使用的是Rspec3.x。

還存在另一種方法 ，您可以顯式列出要忽略的gem：

config.filter_gems_from_backtrace "ignored_gem", "another_ignored_gem"
