There are a few different patterns that can be used when building components in an object oriented programming language to help make unit testing automation easier. The most common patterns are the Model View Controller (MVC) pattern, the Observer pattern, and the Model View ViewModel (MVVM) pattern.
The Model View Controller (MVC) pattern is often used to build components that ease unit testing automation because it separates the code that handles the data (the model) from the code that handles the user interface (the view). This separation makes it easier to test the model without having to worry about the view, and vice versa.
The Observer pattern is often used to build components that ease unit testing automation because it allows the code that handles the data (the model) to notify the code that handles the user interface (the view) of changes. This notification system makes it easier to test the model by ensuring that the view is always up-to-date.
The Model View ViewModel (MVVM) pattern is often used to build components that ease unit testing automation because it separates the code that handles the data (the model) from the code that handles the user interface (the view) and the user input (the view model). This separation makes it easier to test the model and the view model without having to worry about the view, and vice versa.

Which pattern should we follow in unit test?
There is no single answer to this question as there are many different approaches to unit testing, and the best approach for a given project will depend on the specific details of that project. However, some general tips for writing effective unit tests include:
-Making sure that each test is isolated from the others, so that changes to one test will not affect the others
-Keeping the tests small and focused on a single functionality
-Designing the tests in such a way that they can be easily run and monitored
-Using a tool like JUnit or TestNG to automate the running of the tests
