RSpec 2 的 RCov 无法正确检测覆盖范围？（不是铁轨！）

前言
我刚刚开始接触 Ruby，不仅尝试学习该语言，还尝试学习一些开发策略。作为初学者，我专注于测试和行为驱动开发。（是的，我这样做是为了进行比较）

在我的小型软件项目中，我使用

UnitTest (TDD)
Cucumber (BDD)
Rspec（TDD 和 BDD）

在不同的地方，我遇到了 RCov 作为一种工具来告诉我有多少我正在测试的实际代码。

我在 Rakefile 中设置了以下 RakeTask，用于 UnitTests 的协方差分析：

desc "Run RCov to get coverage of UnitTests"
Rcov::RcovTask.new(:rcov_units) do |t|
  t.pattern = 'tests/**/tc_*.rb'
  t.verbose = true
  t.rcov_opts << "--html"
  t.rcov_opts << "--text-summary"
  t.output_dir = "coverage/tests"
end

这工作正常，我在 coverage/tests 中得到了一个漂亮的彩色 HTML 报告。

问题介绍
类似地，我为 RCov 编写了以下 RakeTasks，用于我的规范的覆盖率分析：

desc "Run RCov to get coverage of Specs"
Rcov::RcovTask.new(:rcov_spec) do |t|
  t.pattern = 'spec/**/*_spec.rb'
  t.verbose = true
  t.rcov_opts << "--html"
  t.rcov_opts << "--text-summary"
  t.output_dir = "coverage/spec"
end

问题定义
然而，coverage/spec 中生成的 HTML 报告看起来不完整，几乎失败。

没有一个被测试的方法体被标记为被覆盖并因此被标记为红色。不过，我 100% 确定它们是在规范内执行的。只有 def method_name(args) 和 class ClassName 行标记为“绿色”。（以及带有 attr_reader :instance_variable 的行）

我错过了什么吗？

$: ruby --version  
ruby 1.8.7 (2011-02-18 patchlevel 334) [x86_64-linux]

$: rspec --version

$: rcov --version  
rcov 0.9.11 2010-02-28

$: rake --version  
rake, version 0.9.2

Preface
I've just started getting into Ruby and try to not only learn the language but also some development strategies. As kind of a beginner I'm concentrating on Test and Behaviour Driven Development. (yes, I'm doing both for comparison purposes)

With my small software project I'm using

UnitTest (TDD)
Cucumber (BDD)
Rspec (TDD and BDD)

On various places I encountered RCov as a tool for telling me how much of my actual code I'm really testing.

I set up the following RakeTask in my Rakefile for the covarage analysis of the UnitTests:

desc "Run RCov to get coverage of UnitTests"
Rcov::RcovTask.new(:rcov_units) do |t|
  t.pattern = 'tests/**/tc_*.rb'
  t.verbose = true
  t.rcov_opts << "--html"
  t.rcov_opts << "--text-summary"
  t.output_dir = "coverage/tests"
end

This works fine and I'm getting a nice coloured HTML report in coverage/tests.

Problem Introduction
Similar I wrote the following RakeTasks for RCov to be used for coverage analysis of my specs:

desc "Run RCov to get coverage of Specs"
Rcov::RcovTask.new(:rcov_spec) do |t|
  t.pattern = 'spec/**/*_spec.rb'
  t.verbose = true
  t.rcov_opts << "--html"
  t.rcov_opts << "--text-summary"
  t.output_dir = "coverage/spec"
end

Problem Definition
However, the generated HTML report in coverage/spec looks somehow incomplete and almost failed.

None of the tested method bodies are marked as covered and thus red. However, I'm 100% sure they are executed within the specs. Only the lines def method_name(args) and class ClassName are marked 'green'. (as well lines with attr_reader :instance_variable)

Am I missing something?
