The benefits of this pattern

Most of the time, the Facade Pattern is adopted for implementation parts that have a relatively high degree of complexity and are used in several places of an application, wherein large pieces of code can be replaced with a simple call to the created Facade, leading not only to less code repetition, but also helping us to increase the readability of the implementation. Since the Facade methods are usually named by the higher-level application concepts that they encapsulate, the resulting code is also easier to understand. The simplified API that a Facade provides through its convenient methods, leads to an implementation that is easier to use, understand, and also write unit tests for.

Moreover, having Facades to abstract complex implementations proves its usefulness in cases where there is a need to introduce a change to the business logic of the implementation. In case a Facade has a well-designed API with a prediction for future requirements, such changes can...
