Question

I’m trying to unit test a model called UserModel. My RSpec code is:

# user_model.rb
require 'user_model'

describe UserModel do
   result = UserModel.add("test","test")
   result.should eq(1)
end

The line require 'user_model' raises an error:

ERROR : `./user_model.rb:1: uninitialized constant ActiveRecord (NameError)`

Is that line for importing the class UserModel?

If you don’t include your Rails environment in your test system then the results will be unpredictable. A typical test includes test_helper at the very least, which by default loads in Rails and sets up the proper database connections.

Every model when created with rails generate model will come with a sample test you can customize.
