Question

在Rspec 3中，包括spec/spec_helper.rb文件的首选方法是在.rpsec文件中添加标志：

--require spec_helper

无需在每个_spec文件的顶部添加引用：

# include 'spec/spec_heler'  <-- removed

describe FooController do
end

但是，当我尝试通过Rake运行Rspec测试时，出现错误：

$ rake test
Traceback (most recent call last):
/Users/<user>/Projects/sinatra/mod/spec/app/controllers/foo_controller_spec.rb:1:in `<top (required)>': uninitialized constant FooController (NameError)
rake aborted!
Command failed with status (1)

Tasks: TOP => test
(See full trace by running task with --trace)

建议不要读取.rpsec和spec_helper文件。

Rakefile的内容：

require 'rake/testtask'

Rake::TestTask.new do |t|
  t.pattern = "spec/**/*_spec.rb"
end

spec/spec_helper.rb的内容：

require 'rack/test'
require 'rspec'

require File.expand_path '../../app.rb', __FILE__

RSpec.configure do |config|

  # rack
  config.include Rack::Test::Methods

  ...
end

如何纠正此问题？

Answer 1

我需要更改Rakefile：

require 'rspec/core/rake_task'

task :default => :spec

RSpec::Core::RakeTask.new(:spec) do |t|
  t.pattern = "spec/**/*_spec.rb"
end

我还需要更改spec/spec_helper.rb文件：

# added
require 'rubygems'
require 'bundler/setup'

# existing
require 'rack/test'
require 'rspec'

require File.expand_path '../../app.rb', __FILE__

RSpec.configure do |config|

  # rack
  config.include Rack::Test::Methods

  ...

end

从rspec运行测试时：

$ rspec
...
Finished in 0.07952 seconds (files took 0.63445 seconds to load)
15 examples, 0 failures, 1 pending

从rake运行测试时：

$ rake
/Users/<user>/.rbenv/versions/2.3.3/bin/ruby -I/Users/<user>/.rbenv/versions/2.3.3/lib/ruby/gems/2.3.0/gems/rspec-support-3.8.0/lib:/Users/<user>/.rbenv/versions/2.3.3/lib/ruby/gems/2.3.0/gems/rspec-core-3.8.0/lib /Users/<user>/.rbenv/versions/2.3.3/lib/ruby/gems/2.3.0/gems/rspec-core-3.8.0/exe/rspec --pattern spec/\*\*/\*_spec.rb
...
Finished in 0.08885 seconds (files took 0.70133 seconds to load)
15 examples, 0 failures, 1 pending

但是不确定为什么要添加$LOAD_PATH。

在Rakefile中包含spec_helper
