civiccc/db-query-matchers: RSpec matchers for database queries

RSpec matchers for database queries made by ActiveRecord.

Examples from the docs:

  context 'when we expect exactly 1 query' do
    it 'makes database queries' do
      expect { subject.make_one_query }.to make_database_queries(count: 1)
    end
  end

  # ...

  context 'when we only care about manipulative queries (INSERT, UPDATE, DELETE)' do
    it 'makes a destructive database query' do
      expect { subject.make_one_query }.to make_database_queries(manipulative: true)
    end
  end

  # ...

  context 'when we only care about queries matching a certain pattern' do
    it 'makes a destructive database query' do
      expect { subject.make_special_queries }.to make_database_queries(matching: 'DELETE * FROM')
    end
  end

Seems like this could simplify some specs by quite a bit, but still be just as expressive.
