在 rspec 中运行 ruby​​ 调试? [英] Running ruby debug in rspec?

问题描述

我正在尝试让 Ruby 调试器在我的规范之一中运行:

I'm trying to get Ruby debugger running in one of my specs:

describe User do
  it "should be valid" do
    debugger
    User.new.should be_valid
  end
end

当我运行 rspec 时，我得到:

When I run rspec though, I get:

debugger statement ignored, use -d or --debug option to enable debugging

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/

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.

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.

谢谢，贾斯汀.

推荐答案

通过在规范顶部包含require 'ruby-debug'，您将得到您想要的:

You will get what you want by including require 'ruby-debug' at the top of your spec:

# 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

然后您将正常运行 rake spec 或 rspec

You would then run rake spec or rspec as normal

注意:我现在更喜欢 Ruby 2.0+ 和 pry.这几乎是相同的过程:

NOTE: I now prefer Ruby 2.0+ and pry. It is pretty much the same process:

require 'spec_helper'
require 'pry-debugger'

describe User do
  it "should be valid" do
    binding.pry
    expect(User.new).to be_valid
  end
end

此外，我通常在我的 spec_helper 文件中放置这样的需求，以便 pry-debugger 可用于我的所有规范.

Also, I generally put requires like this in my spec_helper file, so that pry-debugger is available to all of my specs.
