如何使用测试单元生成HTML测试报告

Question

我有一个在test :: unit框架中开发的简单项目，它工作正常。我想生成一个HTML测试报告，说明我使用传递/失败状态和其他相关数据执行的测试。

我有三个文件：

Rakefile（调用runner.rb文件）：

task :default => :TestRunner
    desc "run suite test"
    task :TestRunner  do
      ruby "D:/TestUnit/runner.rb"
    end

runner.rb（执行测试套件）：

base_dir = File.expand_path(File.join(File.dirname(__FILE__), ".."))
test_dir = File.join(base_dir, "testUnit/suite.rb")

require 'test/unit'

exit Test::Unit::AutoRunner.run(true, test_dir)

suite.rb（包含所有测试）：

gem "test-unit"
require "test/unit"

class Test1< Test::Unit::TestCase
description "Test Case for adding two values..!!", :test_add
description "Test Case for subtracting two values..!!", :test_sub

  def setup
  puts "running the setup........."
    @number1 = 4
  @number2 = 2  
  end
  def test_add
  puts "asserting the add function: " + description
  numb1=@number1+@number2
    assert_equal(7, numb1 + 1, "added correctly")
  end

  def test_sub
  puts "asserting the subtract function: " + description
  numb2=@number1-@number2   
    assert_equal(2, numb2 - 0, "subtracted correctly")
  end

  def teardown
  puts "running teardown......."
    @number = nil   
  end
end

生成HTML测试报告还需要做什么？
