Rspec极慢 [英] Rspec extremely slow
问题描述
即使使用后卫&,我的rspec测试似乎也运行得非常慢.孢子.
My rspec tests seem to run extremely slow even with guard & spork.
Finished in 5.36 seconds
13 examples, 2 failures
我知道我可以做一些优化我的测试的事情.减少与数据库的交互,但是我强烈怀疑spec_helper的设置不正确.我在与3.2版的Mongoid混在一起.每次运行后,数据库清理器都会清理.
I understand that there are several things I can do to optimize my tests & reduce interaction with the database, but I strongly suspect that the spec_helper has been improperly setup. I'm on rails 3.2.11 with mongoid. Database cleaner cleans up after every run.
spec_helper.rb
require 'rubygems'
require 'spork'
Spork.prefork do
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rspec'
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
DatabaseCleaner[:mongoid].strategy = :truncation
RSpec.configure do |config|
config.infer_base_class_for_anonymous_controllers = false
config.order = "random"
config.filter_run focus: true
config.filter_run_excluding :remove => true
config.run_all_when_everything_filtered = true
config.include Mongoid::Matchers
config.include Capybara::DSL
ActiveSupport::Dependencies.clear
end
end
Spork.each_run do
Fabrication.clear_definitions
RSpec.configure do |config|
config.before(:each) do
DatabaseCleaner.clean
end
end
end
更新:问题出在我的一项测试中.这花了3秒钟.请检查@Sam Peacey的答案以获取我用来获得以下结果的命令
UPDATE: The problem was with one of my tests. It was taking 3 seconds. Please check @Sam Peacey's answer for the command I used to get the below result
Dynamic Model should destroy collection when related source is destroyed
2.46 seconds ./spec/models/dynamic_model_spec.rb:10
Dynamic Model Validations should validate uniqueness
0.66357 seconds ./spec/models/dynamic_model_spec.rb:69
推荐答案
您可以通过使用-p
/--profile
标志运行rspec来配置您的规格:
You can profile your specs by running rspec with the -p
/ --profile
flag:
rspec spec -p [-drb, and whatever else]
这将列出10个最慢的示例及其执行时间.您可以通过为-p标志提供可选计数来更改默认值10.使用rspec --help
This will list the 10 slowest examples with their execution time. You can change the default of 10 by providing an optional count to the -p flag. More info by using rspec --help
