Separate sprint for testing user stories and tasks

Hi all, I am new to Scrum. I am not sure how to include the testing part of the stories in the sprint. The way we implement Scrum, we have many small tasks in the sprint backlog, and each of these tasks need to be tested for regression and quality control. I am not sure how to include the testing aspect in the sprint. Should it be a part of the current sprint, or should we design a separate sprint for testing activities? The sprints could run one after the other. Is this possible in Scrum? Many thanks.
