Question

我有这个规范，我想翻译成MiniTest。

describe User do
  subject { build(:user, provider: 'foo') }

  # don't validate presence of password when provider is present
  it do
    should_not validate_presence_of(:password)
  end
end

我试过这个。我收到undefined method 'should_not' for UserTest

错误

class UserTest < ActiveSupport::TestCase
  def setup
    @user = build_stubbed(:user)
  end

  test "responds to name" do
    assert_respond_to @user, :name
  end

  should validate_presence_of(:password)

  test "do not validate presence of password when provider is present" do
    build_stubbed(:user, provider: 'foo')
    should_not validate_presence_of(:password)
  end
end

我想更改一个测试的上下文，其中主题获得provider属性，该属性应该禁用密码字段上的状态验证器。

这是完整的错误：

UserTest#test_presence_of_password:
NoMethodError: undefined method `should_not' for #<UserTest:0x007feaa82c1c68>
    test/models/user_test.rb:45:in `block in <class:UserTest>'

我发现更好的方法是恢复旧的MiniTest：

  test "uniqueness of email with a different provider" do
    email_user = create(:user, email: "foo@bar.com")
    facebook_user = build_stubbed(:facebook_user, email: "foo@bar.com")

    assert facebook_user.valid?, "should be valid with same email if provider is different"
  end

看看minitest-rails-shoulda宝石。如果你使用它，我认为测试看起来像这样：

describe User do
  subject { build_stubbed(:user) }

  it { must validate_presence_of(:password) }

  describe "when a provider is present" do
    subject { build_stubbed(:user, provider: 'foo') }

    it { wont validate_presence_of(:password) }      
  end
end

如何用MiniTest / shoulda语法编写此规范？
