I want to use FactoryGirl data to spin the RSpec description.

We are trying to commonize almost duplicate tests using each as shown below.

RSpec.describe Hoge, type::model do
  describe'describe1'do
    [create(:foo), create(:bar)].each do|v|
      describe"#{v.name}"do
        # Test with v
      end
    end
  end
end

In this case, the following error will not work.

How can each make it common?

ruby-on-rails rspec

Have you forgotten to write it? In addition, it is not a way to use each, but if you want to make it common, I think it is better to use shared_examples or shared_context.

In this case, would it be like the following?

RSpec.describe Hoge, type::model do
  shared_examples "describe1" do
    it do 
      # Test with v
    end
  end

  context "foo" do
    let(:v) {create:foo}
    it_behaves_like 'describe1'
  end

  context "bar" do
    let(:v) {create:bar}
    it_behaves_like 'describe1'
  end
end
