Side Note : We are going to be working with functions that require actions to complete before moving on to subsequent steps. This allows time to render pages, execute interactions, etc before proceeding. Many of these steps are non-blocking so we need to rely on promises to pause execution.
Most important here is the Page object — we will be using this to access the content that is being rendered to the UI. This will also be where we specify where we are navigating to, what elements we are interacting with, and where we will be running our scripts.
Once we have our session initialized and our domains defined we can start navigating the site. We want to pick a starting point so we use the Page domain that we enabled above to navigate to:.
