Running ruby debug in rspec?
提问by Allyl Isocyanate
I'm trying to get Ruby debugger running in one of my specs:
我正在尝试让 Ruby 调试器在我的规范之一中运行：
describe User do
it "should be valid" do
debugger
User.new.should be_valid
end
end
When I run rspec though, I get:
但是，当我运行 rspec 时，我得到：
debugger statement ignored, use -d or --debug option to enable debugging
I've tried the following:
我尝试了以下方法：
rake spec --debug
rake spec --debug --trace
rake spec:models --debug
bundle exec rspec --debug
bundle exec rspec --debug spec/models/
bundle exec rspec --d spec/models/
bundle exec "rspec --debug" spec/models/
bundle exec rspec --debugger spec/models/
bundle exec --debugger rspec spec/models/
bundle --debugger exec rspec spec/models/
bundle --debugger exec rspec spec/models/
bundle exec --debugger rspec spec/models/
bundle exec rspec --debugger spec/models/
Any ideas on how to exec rspec in the right way? I'm on Rails 3.0.5, Ruby 1.9.2, RSpec 2.5.1, ruby-debug19.
关于如何以正确的方式执行 rspec 的任何想法？我在使用 Rails 3.0.5、Ruby 1.9.2、RSpec 2.5.1、ruby-debug19。
Thanks, Justin.
谢谢，贾斯汀。

You will get what you want by including require 'ruby-debug'at the top of your spec:
通过包含require 'ruby-debug'在规范的顶部，您将获得所需的内容：
# spec/models/user_spec.rb
require 'spec_helper'
require 'ruby-debug'
describe User do
it "should be valid" do
debugger
User.new.should be_valid
end
end
You would then run rake specor rspecas normal
然后你会跑rake spec或rspec像往常一样
NOTE:I now prefer Ruby 2.0+ and pry. It is pretty much the same process:
注意：我现在更喜欢 Ruby 2.0+ 和 pry。这几乎是相同的过程：
require 'spec_helper'
require 'pry-debugger'
describe User do
it "should be valid" do
binding.pry
expect(User.new).to be_valid
end
end
Also, I generally put requires like this in my spec_helper file, so that pry-debugger is available to all of my specs.
此外，我通常将这样的需求放在我的 spec_helper 文件中，以便 pry-debugger 可用于我的所有规范。

You can create an .rspecconfiguration file in the root of your project and include the line:
您可以.rspec在项目的根目录中创建一个配置文件并包含以下行：
--debug

For Ruby >= 1.9.2
对于 Ruby >= 1.9.2
You should install the debuggergem instead ofruby-debug19. It you use bundler, you just put this in your Gemfile:
您应该安装调试器gem而不是ruby-debug19。如果你使用bundler，你只需将它放在你的 Gemfile 中：
group :test do
gem "debugger"
end
After that you can just put
之后你可以把
rspec < 3.0
rspec < 3.0
--debug
rspec >= 3.0
rspec >= 3.0
-rdebugger
in your .rspecfile
在你的.rspec文件中
Then you can just run
然后你可以运行
bundle exec rake spec
without any additional arguments. There is no need to modify your source codeeither (not even your test source code)
没有任何额外的参数。有没有必要修改源代码是（甚至不是你的测试源代码）

For ruby 2.0 I use byebug: https://github.com/deivid-rodriguez/byebug
对于 ruby 2.0，我使用 byebug：https: //github.com/deivid-rodriguez/byebug
gem 'byebug'
Code:
代码：
# spec/models/user_spec.rb
require 'spec_helper'
require 'byebug'
describe User do
it "should be valid" do
byebug
User.new.should be_valid
end

The best way I have found to debug in rSpec is by adding the following to your 'spec_helper.rb' file
我发现在 rSpec 中调试的最好方法是将以下内容添加到您的“spec_helper.rb”文件中
def logger
Rails.logger
end
You can then access all the logger methods within your rSpec files and incorporate such things as tagged logging. This of course is for Rails 3 and up. If you have anything prior to Rails 3 then add this instead:
然后，您可以访问 rSpec 文件中的所有记录器方法并合并诸如标记记录之类的东西。这当然适用于 Rails 3 及更高版本。如果您在 Rails 3 之前有任何内容，请添加以下内容：
def logger
RAILS_DEFAULT_LOGGER
end
Once you have your logging statements in place you can enter
准备好日志记录后，您可以输入
tail -f log/test.log
in your terminal shell in order to watch your logging statements while the tests are run.
在您的终端 shell 中，以便在测试运行时查看您的日志记录语句。
Of course in your actual rspec test you would enter something such as
当然，在您的实际 rspec 测试中，您会输入诸如
logger.debug "#{1.class}" # => Fixnum
If you want to filter your debug statements from the rest of your test log simply prepend a random string on to your debug statement and pipe the output of the tail command to grep.
如果您想从测试日志的其余部分过滤调试语句，只需在调试语句中添加一个随机字符串，并将 tail 命令的输出通过管道传送到 grep。
Example:
例子：
logger.debug "random_string #{1.class}" # => Fixnum
tail -f log/test.log | grep random_string

I've changed my opinion on this. You should install pry, pry-doc, and pry-debug, pry-debugger, and pry-rails. Then use binding.pry in your code to open an interactive debugger console that rules the world!
我已经改变了我对这件事的看法。您应该安装 pry、pry-doc 和 pry-debug、pry-debugger 和 pry-rails。然后在您的代码中使用 binding.pry 打开一个统治世界的交互式调试器控制台！

The best and cleanest option is to use --requirein your .rspecfile. What you put depends on which gem you use for debugging.
最好和最干净的选择是--require在您的.rspec文件中使用。您放置的内容取决于您用于调试的 gem。
--color
--require pry
--require rails_helper
These correspond to command line options (-d or --debug is now deprecated).
这些对应于命令行选项（-d 或 --debug 现在已弃用）。
Feel free to use debugger, ruby-debugor pry(pry-rails in your Gemfile).
随意使用debugger,ruby-debug或pry（在你的 Gemfile 中撬轨）。
For your Gemfile:
对于您的 Gemfile：
group :test, :development do
gem 'pry-rails'
end
Putting require 'ruby-debug'etc. at the top of your spec is simply more tightly coupled -- especially since here the top voted comment suggests putting it individually in ALL your files. With the new .rspecfile you shouldn't need to put require 'spec_helper'or require 'rails_helper'at the top of your files anymore.
将require 'ruby-debug'etc. 放在规范的顶部只是更紧密地耦合 - 特别是因为在这里投票最高的评论建议将它单独放在所有文件中。使用新.rspec文件，您不再需要将require 'spec_helper'或require 'rails_helper'放在文件的顶部。
They make more sense as implicit command line arguments.
它们作为隐式命令行参数更有意义。
