Arc Unit

What Is ArchUnit?

ArchUnit is a testing library used for defining and enforcing dependencies between classes, packages, and/or layers. It can also be used for establishing conventions, like class names, encapsulation or immutability. It supports JUnit 4 and JUnit 5 libraries; therefore, it is very easy to integrate these tests in any pipeline.

Simply put, ArchUnit is a test library that allows us to verify that an application adheres to a given set of architectural rules.

ArchUnit integrates nicely with the JUnit test framework, and so, they are typically used together.

<dependency> <groupId>com.tngtech.archunit</groupId>

<artifactId>archunit-junit4</artifactId> <version>0.14.1</version> <scope>test</scope> </dependency>

 

The first step is to create a set of Java classes that will be checked for rules violations. We do this by instantiating the ClassFileImporter class and then using one of its importXXX() methods:

JavaClasses jc = new ClassFileImporter() .importPackages("com.baeldung.archunit.smurfs");

 

Or by aanotation?

 

@AnalyzeClasses(
        packages = "com.fmr.ap165106.price_acquisition_service",
        importOptions = ImportOption.Predefined.DoNotIncludeTests.class)

Archunit test

  ArchUnit  integrates nicely with the  JUnit  test framework, and so, they are typically used together.  All we have to do is add the  archunit-junit 5  dependency to match our  JUnit  version: < dependency > < groupId > com.tngtech.archunit </ groupId > < artifactId > archunit-junit5 </ artifactId > < version > 0.14.1 </ version > < scope > test </ scope > </ dependency > Step 1: The first step is to create a set of Java classes that will be checked for rules violations . We do this by instantiating the  ClassFileImporter  class and then using one of its  importXXX()  methods: JavaClasses jc = new ClassFileImporter () .importPackages( "com.baeldung.archunit.smurfs" ); Step 2:  Let’s try to implement the first rule defined above using this API. We’ll use the  classes()  method as our anchor and add additional constraints ...

Hexagonal Architecture

Image
Hexagonal Architecture: Hexagonal architecture is a model of  designing software applications around domain logic  to isolate it from external factors. In the domain layer, we keep the code that touches and implements business logic . This is the core of our application. This layer should be isolated from both the application part and infrastructure part. Through  the application layer, the user or any other program interacts  with the application. This area should contain things like user interfaces, RESTful controllers, and JSON serialization libraries. It includes anything  that exposes entry to our application, and orchestrates the execution of domain logic. Finally, the  infrastructure layer is the part that contains anything that the application needs to work,  such as database configuration or Spring configuration. It also implements infrastructure-dependent interfaces from the domain layer.

visitor design pattern

Image
  The Visitor design pattern is a  behavioral pattern  that allows you to add new operations to a group of related classes without modifying their structures. Real-World Example of Visitor Design Pattern A simple example of the Visitor design pattern is in an online shopping cart. Imagine you have different items like books, electronics, and clothing. Each item can accept a visitor that performs actions like calculating the total price or applying discounts. This way, you can add new features without changing the item classes, making the system easier to maintain and update. UML Class Diagram of Visitor design pattern Components of Visitor Design Pattern The Visitor design pattern consists of several key components that work together to enable its functionality. Here’s a breakdown of these components: Visitor Interface : This interface declares a visit method for each type of element in the object structure. Each method is designed to handle a specific element type. Concr...
