## What is Humble Object? The Humble Object pattern is a design pattern used in object-oriented programming. The main idea behind this pattern is to simplify the testing process by separating complex logic into a separate component that can be easily tested. This component is then decoupled from the environment, making it independent and easier to manage. - **Humble Container Adapter**: This refers to the creation of an adapter that helps in integrating with a container. It's humble because it does not contain any business logic and just acts as a bridge between the application and the container. - **Humble Transaction Controller**: This refers to an object that controls transactions but does not have any business logic itself. It simply starts, commits or rolls back transactions as needed. - **Humble Executable**: This is an executable program that contains no logic other than starting up the application. It's responsible for creating the main objects, connecting them together and starting everything up. - **Humble Dialog**: In GUI applications, this refers to dialogs that are stripped of all logic except for managing UI widgets. Any decisions based on user input are delegated to another class. Developers can isolate complex logic from its environment by using these humble objects to make it easier to test. This approach reduces dependencies and makes code more modular and maintainable. --- ## Tags #SoftwareDevelopment #Programming #DesignPattern #ObjectOrientedProgramming #HumbleObjectPattern --- ## Related Concepts - [[Unit Testing]]: Humble Object pattern is often used to facilitate unit testing. By separating complex logic into a testable component, developers can create more effective and efficient unit tests. - [[Dependency Injection]]: This is a technique where an object receives other objects that it depends on. Humble Object pattern can make use of dependency injection to decouple the logic from its environment. - [[Mocking]]: In testing, mocking is the act of replacing some dependencies of an object with 'mock' objects that simulate the behavior of the real ones. The Humble Object pattern facilitates mocking by making dependencies explicit and therefore easier to replace in tests. - [[Single Responsibility Principle (SRP)]]: This principle states that a class should have only one reason to change. The Humble Object pattern aligns with SRP by ensuring that each component has a single responsibility, thus making it easier to maintain and test. - [[Inversion of Control (IoC)]]: IoC is a design principle in which custom-written portions of a program receive the flow of control from a generic framework. The humble object can be seen as an application of IoC, as it involves separating concerns into different objects and controlling their interactions from a higher level. - [[Test Driven Development (TDD)]]: TDD is a software development process where developers write tests before writing the code itself. The Humble Object pattern can facilitate TDD by making components more testable and modular.
