how to make validates inclusion true or false work in testing rails?

i'm using gem shoulda for my testing, if i have some validates like this in my model :

class Draw < ActiveRecord::Base    
    validates :available, inclusion: { in: [true, false] }
end

how to make this validate work in testing?, when i try this code in my model testing :

require 'test_helper'

class DrawTest < ActiveSupport::TestCase    
  should ensure_inclusion_of(:available).in_array([true, false])
end

i get error like this :

DrawTest#test_: Draw should ensure inclusion of available in [true, false].  [/home/my_user/.rvm/gems/ruby-2.0.0-p451/gems/shoulda-context-1.2.1/lib/shoulda/context/context.rb:344]:
[true, false] doesn't match array in validation

Under version 2.6.2, should-matchers issues the following warning when testing ensure_inclusion_of(:available).in_array([true, false]):

Warning from shoulda-matchers:

You are using `ensure_inclusion_of` to assert that a boolean column allows
boolean values and disallows non-boolean ones. Assuming you are using
`validates_format_of` in your model, be aware that it is not possible to fully
test this, and in fact the validation is superfluous, as boolean columns will
automatically convert non-boolean values to boolean ones. Hence, you should
consider removing this test and the corresponding validation.

It seems that you should just remove the test and validation.
