只需运行rspec，我的所有测试都会持续通过。我已经安装了Guard，现在我遇到了不一致的问题。具体来说，如果我对控制器进行了更改，其规范可能会失败1或3或6.它们似乎植根于数据库锁定，导致其他测试使用不一致的数据。
我试图找到类似的问题，但我想出的只是rspec和sqlite解决方案。我确信这是一个Guard配置问题，因为正如我所说，测试是从命令行运行的。
以下是我在同一个文件中进行一些更改并且每次都得到不同结果的示例：

我认为我的Guardfile就是你启动守卫时的例子：
require 'active_support/inflector'
# A sample Guardfile
# More info at https://github.com/guard/guard#readme
# Note: The cmd option is now required due to the increasing number of ways
# rspec may be run, below are examples of the most common uses.
# * bundler: 'bundle exec rspec'
# * bundler binstubs: 'bin/rspec'
# * spring: 'bin/rsspec' (This will use spring if running and you have
# installed the spring binstubs per the docs)
# * zeus: 'zeus rspec' (requires the server to be started separetly)
# * 'just' rspec: 'rspec'
guard :rspec, cmd: 'bundle exec rspec' do
watch(%r{^spec/.+_spec\.rb$})
watch(%r{^lib/(.+)\.rb$}) { |m| "spec/lib/#{m[1]}_spec.rb" }
watch('spec/spec_helper.rb') { "spec" }
# Rails example

watch(%r{^app/(.*)(\.erb|\.haml|\.slim)$}) { |m| "spec/#{m[1]}#{m[2]}_spec.rb" }

包括spec文件：
describe V1::PlayersController, type: :controller do
before :each do
controller.request.env['HTTP_AUTHORIZATION'] = ActionController::HttpAuthentication::Token.encode_credentials('asdfasdfasdfasdfasdfasdf')
end
after :each do
ActiveRecord::Base.subclasses.each(&:delete_all)
end

end
it 'fails when no token exists in client record' do
FactoryGirl.create :client, name: "joe"
get :index, format: :json
expect(response).not_to be_successful
end
end
describe "GET players with proper auth" do
let!(:player_before_transact_points) { FactoryGirl.create :player, name: "Sam", default_pull_rate: 105 }

let!(:client) { FactoryGirl.create :client, name: "joe", auth_token: "asdfasdfasdfasdfasdfasdf" }

expect(power_up_names).to match_array(["Sam", "Ma"])
end
end

end
it "should default score to 0" do

我有类似的问题，因为我没有意识到我有两个保护进程在运行。因此，请确保只有一个进程正在访问数据库。
答案 1 :(得分：0)
我创建了一个新的RAILS_ENV，名为“ci＆＃39;并在其中运行Guard。看起来这个问题可能是RubyMine特有的。请参阅@ justingordon更详细的答案：
