[ruby] How do you run a single test/spec file in RSpec?

Although many great answers were written to this question, none of them uses the Rspec tags approach.

I use tags to run one or more specs in different files -- only those related to my current development task.

For example, I add the tag "dev" with the value "current":

it "creates an user", dev: :current do
  user = create(:user)
  expect(user.persisted?).to be_truthy
end

then I run

bundle exec rspec . --tag dev:current

Different tags/values can be set in individual specs or groups.
