Week 11 Blog

This week’s blog will cover the main purpose of Object Oriented Testing and its usefulness. You most likely have heard the term “Object Oriented Programming”, which refers to a style of programming that utilizes classes, abstract classes, inheritance, polymorphism, concurrency, and more as a way of organizing code. These tools can be useful when dealing with multiple lines of code because it can be broken down into multiple files creating a more organized and readable product. Having a file with thousands of lines of code is a developers nightmare. Object Oriented Testing aims to test these systems and ensure they are behaving as expected. It is possible to have too much inheritance in a program, making it difficult to find where a piece of code is located, slowing down development. Unlike other test methods that primarily test function behavior, Object Oriented Testing analyzes the behavior of the entire class and its interactions with other files.

There are multiple techniques to Object Oriented Testing: Unit Testing, Integration Testing, Inheritance Testing, Polymorphism Testing, and Encapsulation Testing just to name a few. Unit testing refers to testing of individual components of the class before testing the interactions it has with other classes. Initially testing the classes functions will prevent scenarios where you can’t locate the bug in the program because there are too many inherited classes. An example is testing each function and ensuring the behavior. Integration testing refers to testing objects of different classes and ensuring they behave properly with all the components. Inheritance testing aims to test the relationship between parent and child classes. This technique of testing also tests overridden functions are properly implemented and are actually overriding the function. Polymorphism testing aims to verify that objects of different types can be used interchangeably. This type of testing ensures the behavior across all types of objects. Encapsulation testing tests access control and ensures the data being accessed is allowed to be accessed by the user.

The main benefits of running these tests is to detect defects early on rather than later in the development process. For this reason, it’s recommended to run tests throughout development. Object Oriented Testing ensures our project is modular, making it easier to maintain. In addition, it becomes easier to implement new features and classes without impacting existing code. Due to the never-ending demands of modern applications and the ever-evolving tech industry, the scalability of a program is crucial.
