Once you have defined the steps you need to describe your high level tests, you need to implement these steps. In an automated web test, test steps represent the level of abstraction between your Page Objects (which are designed in terms of actions that you perform on a given page) and higher-level stories (sequences of more business-focused actions that illustrate how a given user story has been implemented). Steps can contain other steps, and are included in the Thucydides reports. Whenever a step is executed, a screenshot is stored and displayed in the report.
