Clickable Actions
To test the counter app, we need to click the buttons and assert that the value increases and decreases.
Elements with "type": "clickable" also have access to click().
The page object declares a clickable element called buttons, which returns all the buttons in the component.
The page object also declares a count element, which selects the span element that holds the count.
The default value of the counter is 0. Because the buttons element is clickable, it has access to click() in test code.
The test code clicks the plus (+) button 3 times and the minus (-) button one time. It then calls the getText() basic action API to assert the value, which should be 2.
