抑制Rspec 3的回溯

Question

我正在使用rspec 3.2.0和capybara 2.4.4，并在我的spec_helper.rb文件中有如下所示

config.full_backtrace=false

在大多数错误中，我得到了回溯。

Failure/Error: check 'un_student_3'
 Capybara::ElementNotFound:
   Unable to find checkbox "un_student_3"
 # /Users/115698/.rvm/gems/ruby-2.1.1@match_maker/gems/capybara-2.4.4/lib/capybara/node/finders.rb:41:in `block in find'

 # ./spec/features/students/student_spec.rb:56:in `block (2 levels) in <top (required)>'

我怎么才能关掉这个？

Answer 1

基于对这个问题( How do I shorten the backtrace for a test failure in RSpec 2? )的行(或注释)的阅读，这样做的方法放在您的spec_helper.rb文件中。

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