似乎我想做与大多数人在测试 Rails 时要求的相反...
如何测试 FOR ActiveModel::MassAssignmentSecurity::Error。我已经明白了,只是想知道如何使它使我的测试用例变成绿色而不是红色。
当前测试:
describe Tag do
let(:tag) { FactoryGirl.create(:tag) }
subject { tag }
describe "when tag name is sent directly" do
before { tag = Tag.new(name: "New") } # <- what I want to raise the error
it { should_not be_valid } # <- doesn't make it to this line
end
end
我应该如何将其构建为适当的测试?我试过了:
lambda do
tag = Tag.new(name: "NEW")
end.should raise_error
但这对我也不起作用,我明白了
Exception encountered: #<NoMethodError: undefined method `raise_error' for #<Class:0x00000102525c08>>
