ruby-on-rails - 在 rspec : `formatted_backtrace' : undefined method `backtrace' 中运行所有项目规范时出错

Question

每当我在完成所有测试用例后尝试为整个项目(有超过 1000 个测试)运行 rspec 时，我都会收到以下错误:

当我只运行有限数量的测试用例时，比如一个文件或一个文件夹，一切正常。

这是我的.rspec 文件

--color
--require rails_helper

和spec_helper.rb

require "rack_session_access/capybara"
RSpec.configure do |config|
end

所以没有什么可疑的，至于我

关于如何解决这个问题有什么想法吗？

Answer 1

将此添加到您的 .rspec 文件中:

--require spec_helper

这保证在每个规范之前都需要您的 spec_helper。
