我正在使用 rspec 3.2.0 和 capybara 2.4.4 并在我的 spec_helper.rb 文件中如下所示
config.full_backtrace=false
对于大多数错误，我都会得到回溯，例如
Failure/Error: check 'un_student_3'
Capybara::ElementNotFound:
Unable to find checkbox "un_student_3"

我怎样才能关闭它？
基于对这个问题的字里行间（或评论）的阅读：如何缩短 RSpec 2 中测试失败的回溯？ https://stackoverflow.com/questions/5048749/how-do-i-shorten-the-backtrace-for-a-test-failure-in-rspec-2%5D，执行此操作的方法是放入您的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)/
