In the Workflow Manager, you can configure a Check-in action that checks in a page toward specific publishing targets. By specifying publishing targets, you can select the environments to which you'll publish content. For example, you could check in an updated page to a test environment without sending it to production.

To define the publishing targets toward which a page will be checked in during workflow, click New or Edit in the Workflow Manager's Transitions pane. On the Actions tab, click the + button and select the Check-in action from the menu.

If you expand the Check-in action and click Change, you'll see the Check in pages to be published dialog, where you can select publishing profiles.
