问题
I'm developing a gem for Rails 3 and came across an error in my test suit when running it under Ruby 1.8.7 at travis-ci.org:
/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)

this is a link to the failing job: https://travis-ci.org/#!/pokonski/public_activity/jobs/2586051
Everything works just fine in Ruby > 1.8.7.
My relevant part of .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
and Gemfile:
source :rubygems
gemspec
gem 'yard'
What's interesting, when running the tests locally with ruby-1.8.7-p370 I get an error with a different missing method:
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'
More source code for the failing lines: https://github.com/pokonski/public_activity/blob/master/test/test_common.rb#L85
Anyone have a clue what's going on?
回答1:
Turns out it was because of the test_generators.rb which used Rails::Generators::TestCase, which in turn inherited from TestUnit.
Mocha was incorrectly monkey patching Test::Unit instead of MiniTest because of this. The solution was to require test_helper
in test_generators.rb and force MiniTest gem to the 3.2.0 version.
