Question

我正在尝试这样做：

  describe "should fail on create if the name is shorter than 5 characters" do
    group = Factory.build(:group, :name => "a")
    group.should be_invalid
    group.should have(1).error_on(:name)
  end

但是我收到以下错误：

/spec/models/group_model_spec.rb:22: undefined local variable or method `be_valid' for #<Class:0x105d13ed0> (NameError)

想法？感谢

Answer 1

这是正确的语法：

group.should_not be_valid

rspec - 为什么be_valid不起作用
