The Selenium extension for Screenplay provides numerous Actions, each of which represents one of the smallest possible interactions with a web browser/page.
Broadly, these actions fall into the following categories:
Actions which work with HTML elements (targets), such as "click on a specified element" or "type some keys into an input box". These actions will always require a target as a parameter.
Actions which interact directly with the web browser, such as "take a screenshot" or "clear the cookies for the current domain".
Actions which represent waiting for something, such as "wait until the progress bar reaches 100%" or "wait until the shopping cart items are visible".
Recall that Screenplay Actions do something without getting any result.
To interrogate a web page (to observe it in some manner), use one of the Selenium extension's Questions.
Below is a summary of each of these actions' usage, with a link to their detailed documentation page.
