Robot Pattern

What is the use case to use a robot pattern

• Consider a scenario where there is a check-box and we have a logic that sets it checked/not-checked based on logic.
• Now if we change the check-box to a image-view then a lot of things need to be modified.

Solution - Separate what from how

• By separating what and the how our tests are more maintainable.
• In above example,
  • What -> whether the checkbox needs to be checked.
  • How -> whether the widget is checked.

Robot Pattern

• This pattern exposes an API that separates what and the how.
