Uninitialized constant while trying to include hel

问题:

The module that I am trying to include is located here: test/unit/helpers/test_helpers.rb

Looks like:

module TestHelpers
end

I am trying to include it in: test/unit/app/models/abc.rb

class Abc < ActiveSupport::TestCase
include TestHelpers
end

gives the following error:

Error executing test/unit/app/models/abc.rb uninitialized constant Abc::TestHelpers

Any ideas why this might be happening?

回答1:

To include a module into your class, you need to require that file.

require 'test_helpers'

Add this line at the top of your model class.
