在Rails 4上使用RSpec保护,发出很多警告

Question

我想知道如何在运行简单的测试时关闭所有这些警告:

[1] guard(main)>

16:59:46 - INFO - Running all specs

我正在运行Rails 4.1.1,Ruby 2.1.2p95,以及......

guard (2.6.1)
rspec (3.0.0)
guard-rspec (4.2.9)

我试过跑卫:

guard :rspec, cmd:"ruby -W0 bin/rspec" do

代替:

guard :rspec, cmd:"spring rspec" do

但它没有做任何事情.

这些警告非常烦人,我很确定我没有引起它们.救命!

Answer 1

rspec生成器rails generate rspec:install现在默认将--warnings选项放在.rspec文件中.删除该行,警告将消失.

Answer 2

您可以在测试环境中将警告设置为false,以强制Rspec禁用警告消息.

#spec/spec_helper.rb

config.warnings = false
