eorules

Set of custom ArchUnit rules to ensure Elegant Objects principles respect.

eorules helps you design and craft code that respect strong object-oriented programming paradigm.

✨ Features

• Check that classes are abstract or final
• Check that classes have no static methods
• Check that classes have no getters and no setters
• Check that classes have no private methods
• Check that fields are final
• Check that public methods are defined in interface

📥 Installation

Add the dependency to your project:

<dependency>
    <groupId>com.github.roroche</groupId>
    <artifactId>eorules</artifactId>
    <version>${latest.version}</version>
    <scope>test</scope>
</dependency>

🚀 Usage

class ArchitectureTest {

    private final JavaClasses classes = new ClassFileImporter()
        .withImportOption(ImportOption.Predefined.DO_NOT_INCLUDE_TESTS)
        .importPackages("com.example");

    @Test
    void checksClassesAreAbstractOrFinal() {
        new ClassesAreAbstractOrFinalRule().check(this.classes);
    }

    @Test
    void checksThereAreNoStaticMethods() {
        new ClassesShouldHaveNoStaticMethodsRule().check(this.classes);
    }

    @Test
    void checksClassesDoNotHaveGettersOrSetters() {
        new ClassesShouldNotHaveGettersOrSettersRule().check(this.classes);
    }

    @Test
    void checksClassesDoNotHavePrivateMethods() {
        new ClassesShouldNotHavePrivateMethodsRule().check(this.classes);
    }

    @Test
    void checksFieldsAreFinal() {
        new FieldsShouldBeFinalRule().check(this.classes);
    }

    @Test
    void checksPublicMethodsAreDeclaredInInterfaces() {
        new PublicMethodsDeclaredInInterfacesRule().check(this.classes);
    }
}

To bypass the checks, you can annotate your class with @ExcludeFromArchUnit.
