这是我在Gemfile中的组测试开发部分
group :test, :development do
gem 'rspec-rails', '~> 3.0.0'
gem "factory_girl_rails", "~> 4.0"
end
这是我的behavior_spec.rb
require 'spec_helper'
require 'rails_helper'
Rspec.describe Behavior, :type => :model do
describe ".match_all?" do
it "should be true if pattern is nil" do
end
end
end
我搜索了有关获取0 example, 0 failures的其他帖子，但没有任何内容适用于这种情况。非常感谢你提前帮助。
