NoMethodError：minitest和mocha的未定义方法`mock’
我正在为Rails 3开发一个gem，并在travis-ci.org的Ruby 1.8.7下运行它时遇到了我的测试套件中的错误：
/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 # (NoMethodError) 69 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:866:in `map' 70 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:866:in `_run_suite' 71 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:853:in `_run_suites' 72 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:853:in `map' 73 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:853:in `_run_suites' 74 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:826:in `_run_anything' 75 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:1015:in `run_tests' 76 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:1002:in `send' 77 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:1002:in `_run' 78 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:1001:in `each' 79 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:1001:in `_run' 80 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:990:in `run' 81 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/minitest-3.5.0/lib/minitest/unit.rb:748:in `autorun' 82 from /home/travis/.rvm/gems/ruby-1.8.7-p370/gems/rake-0.9.2.2/lib/rake/rake_test_loader.rb:21 83rake aborted! 84Command failed with status (1): [/home/travis/.rvm/rubies/ruby-1.8.7-p370/b...] 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。
我的相关部分.gemspec：
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Gemfile：
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，我遇到了一个错误，它有一个不同的丢失方法：
test_resolving_values(TestCommon): NoMethodError: undefined method `mock' for # /home/piotrek/projekty/public_activity/test/test_common.rb:85:in `test_resolving_values'

有人知道发生了什么事吗？
事实certificate，这是因为test_generators.rb使用了Rails :: Generators :: TestCase，后者inheritance自TestUnit。
由于这个原因，Mocha错误地修补了Test :: Unit而不是MiniTest。 解决方案是在test_generators.rb中要求test_helper并强制MiniTest gem到3.2.0版本。
