Here is a little simplified version of my code:

frozen_string_literal: true
RSpec.describe MyObject do
  let!(:my_object)  { create(:my_object, name: 'This Name') }
  let!(:my_ojbect_2) { create(:my_object_2, obj: my_object) }

  describe '#my_data' do
    subject { my_object.my_data }

    context 'when a' do
      ...
      ...

      it { is_expected.to eq expected_value }
    end

    context 'when b' do
      ...
      ...
      it { is_expected.to eq expected_value }
    end

    context 'when' do
      ...
      ...
      it { byebug }
    end
  end
end

When the test stopped at the byebug, I noticed that my_object was created multiple times in the database. Is there a way to have my_object only create one time?

CodePudding user response：

If multiple copies of test objects are persisting between tests this creates huge problems for your tests, and they cannot be relied on.

You have to have a clean slate between tests. There are a number of ways to do this, but it can get complicated with factories, fixtures, transactional fixtures, etc.

I personally almost always end up using a database cleaner.
