Rspec检查ActiveModel ::错误

Question

有没有更好的方法来编写此规范？这可以 但是 我不喜欢我必须调用f.valid?来填充f.errors。

it "fails to save the record because the name is blank" do
  f = Foo.new
  f.valid?
  f.errors.include?(:name).should be_true
end

Answer 1

it "fails to save the record because the name is blank" do
  Foo.create.errors.should include :name
end
