Robot pattern

Description:
The Robot design pattern is an advanced testing pattern commonly used in Android development to simplify and streamline UI testing. The core idea is to encapsulate the interactions with the UI components in a separate class, referred to as a "Robot," which then exposes high-level methods for test scripts to use. This promotes clean, readable, and maintainable test code by abstracting away the detailed interactions with the UI.

Main elements of the pattern:

1. Robot Class: This class handles UI interactions. It encapsulates the operations that can be performed on the UI, such as clicking buttons, entering text, or verifying text visibility.
2. Test Class: This class uses the Robot class to perform tests. It calls the high-level methods provided by the Robot class, making the test code cleaner and more readable.
3. Fluent Interface: The Robot methods are often designed to return the Robot itself, enabling method chaining for more concise and expressive tests.

Acceptance Criteria:

1. A Robot class is implemented encapsulating UI interactions.
2. A sample test class is provided demonstrating the use of the Robot class.
3. Documentation is updated to include a description of the Robot design pattern and usage examples.

Review the linked Robot pattern overview and the repository contribution guidelines first. Then identify the appropriate pattern package and existing test and documentation conventions; done means a Robot class, a sample test, and usage documentation satisfy all three acceptance criteria.
