Rspec run before block once before multiple it blocks

I have a context block in rspec with multiple it blocks inside it. I want to run a before block to set up data for the it blocks but this data takes a long time to set up and is being used to read only. rspec before(:each) creates and deletes this data after every it block which takes a long time. before(:all) creates the data at the start of all the tests and doesn't delete it.

Is there any way I can have this data created just within the context block and deleted after?

Since RSpec 3 these are officially named before/after(:{example,context}) (see docs).

What you want to accomplish can be done with a before(:context) where you set up the data and an after(:context) where you clean it up.

RSpec.describe Thing do
  before(:context) do
    @thing = Thing.new
  end

  after(:context) do
    @thing.delete
  end

  it "has 0 widgets" do
    expect(@thing.widgets.count).to eq(0)
  end

  it "can accept new widgets" do
    @thing.widgets << Object.new
  end

  it "shares state across examples" do
    expect(@thing.widgets.count).to eq(1)
  end
end
