Rails控制台返回有效语句，但测试失败

Question

对于使用定义的模型

belongs_to :municipal
validates  :name, presence: true
has_one    :gdstore, dependent: :destroy

在控制台中

Neighbourhood.new(name: 'red distrikt').valid?
=> false
Neighbourhood.new(municipal_id: 3272, name: 'red distrikt').valid?
=> true

但是运行这个测试

test "valid if name and municipal id defined" do
  neighbourhood = Neighbourhood.new(municipal_id: 3272, name: 'red distrikt')
  assert neighbourhood.valid?
end

返回

Failure:
NeighbourhoodTest#test_valid_if_name_and_municipal_id_defined [/Volumes/SJT/r/gd /test/models/neighbourhood_test.rb:20]:
Expected false to be truthy.

db模式确认：

create_table "neighbourhoods", force: :cascade do |t|
  t.bigint "municipal_id", null: false

那么这是怎么回事呢？注意:反向断言也会生成错误。我不期望has-one创建无效，因为它可能没有gdstore……

好吧..。带有id: 3272的municipal没有夹具，因此测试错误。
