Abstracting away complexity with Atomic Page Objects


The atom level class for a button provides a single interface for getting text regardless of the underlying component structure


At the molecule level you create a means of interacting with a collection of atom level objects such as tabs in a tab bar


At the organism level you can provide interfaces for complex interactions across a number of molecule and atom level objects



At the page level you coordinate the lower level objects to interact or get the state of the page


These methods can really speed up development as they make it easier to have a consistent means of dealing with accessibility IDs

Interacting with UI elements

Because of the lack of control that Android has using touchAction you need to use the lower level performActions functionality

Enabling code re-use with TypeScript decorators

Thanks to the decorator the StorybookItem class gains the press() method without you needing to write any new code
