运行Rails控制台时未初始化的常量测试

Question

I'm getting uninitialized constant Test when running rails console in terminal. I'm not sure why I just set it up and using the command rails server works.

This is the error I get:

/usr/lib/ruby/vendor_ruby/active_support/test_case.rb:12:in `<module:ActiveSupport>': uninitialized constant Test (NameError)

Answer 1

I ran into this same problem on my Ubuntu 14.04 desktop. Solved in the following way:

sudo apt-get install ruby-test-unit echo require 'test/unit' >> /usr/lib/ruby/vendor_ruby/active_support/test_case.rb

see this link: https://bugs.launchpad.net/ubuntu/+source/ruby-activesupport-3.2/+bug/1319101

Answer 2

I had this issue when copied and pasted the config from shoulda-matchers getting started guide . But I wasn't removing the unused tests frameworks.

To use with RSpec it will be as:

Shoulda::Matchers.configure do |config|
  config.integrate do |with|
    # Choose a test framework:
    with.test_framework :rspec
    # with.test_framework :minitest
    # with.test_framework :minitest_4
    # with.test_framework :test_unit

    # Choose one or more libraries:
    with.library :active_record
    with.library :active_model
    with.library :action_controller
    # Or, choose the following (which implies all of the above):
    with.library :rails
  end
end

the echo command above may not work on all installs of Ubuntu 14.04. You can do a sudo vi and physically edit the test_case.rb file and put the require 'test/unit' after the existing require(s).

First: Why are you not using rvm or rbenv ? You can mess your operational system!

Second: It is not finding any reference to a class named Test. Are you sure is this the name? Have you properly required it? Which Test Framework are you using?
