我正在为 Rails 3 开发一个 gem，在 travis-ci.org 在 Ruby 1.8.7 下运行它时遇到了一个错误：

/home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:874:in `_run_suite': undefined method `run' for #<TestActivist:0xb6936dd4> (NoMethodError)

这是失败工作的链接：https ://travis-ci.org/#!/pokonski/public_activity/jobs/2586051

在 Ruby > 1.8.7 中一切正常。

我的 .gemspec 的相关部分：

  s.add_dependency 'activerecord', '>= 3.0.0'
  s.add_dependency 'activesupport', '>= 3.0.0'
  s.add_dependency 'actionpack', '>= 3.0.0'
  s.add_dependency 'i18n', '>= 0.5.0'

  if RUBY_VERSION == "1.8.7"
    s.add_development_dependency 'minitest', '>= 3.2.0'
  else
    s.add_development_dependency 'simplecov', '>= 0.6.4'
  end

  s.add_development_dependency 'bundler', '>= 1.1'
  s.add_development_dependency 'rake', '>= 0.9'
  s.add_development_dependency 'sqlite3'
  s.add_development_dependency 'mocha', '>= 0.12.1'
  s.add_development_dependency 'rails', '>= 3.0.0' # generators test

和宝石文件：

source :rubygems

gemspec

gem 'yard'

有趣的是，当使用 ruby​​-1.8.7-p370 在本地运行测试时，使用不同的缺失方法会出现错误：

test_resolving_values(TestCommon):
NoMethodError: undefined method `mock' for #<TestCommon:0x7ffdc8a79388>
    /home/piotrek/projekty/public_activity/test/test_common.rb:85:in `test_resolving_values'

有人知道发生了什么吗？

原来是因为 test_generators.rb 使用了 Rails::Generators::TestCase，而后者又继承自 TestUnit。

因此，Mocha 错误地修补了 Test::Unit 而不是 MiniTest。解决方案是test_helper在 test_generators.rb 中要求并将 MiniTest gem 强制为 3.2.0 版本。
