如何在测试 rails 中验证包含 true 或 false 的工作？

我正在使用 gem shoulda对于我的测试，如果我的模型中有这样的验证:

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

当我在模型测试中尝试此代码时，如何使此验证在测试中起作用:

require 'test_helper'

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

我得到这样的错误:

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

如何解决这个问题？

在 2.6.2 版本下，should-matchers 在测试 ensure_inclusion_of(:available).in_array([true, false]) 时发出以下警告:

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.

看来你应该只删除测试和验证。
