Question 1

How to set up ArchUnitNET in a .NET Core project?

Accepted Answer

Install the appropriate NuGet package for your test framework (e.g., TngTech.ArchUnitNET.xUnit), use ArchLoader to load assemblies, and define rules in test classes as shown in the documentation example. Ensure tests run in Debug configuration for best results.

Question 2

ArchUnitNET vs. NDepend: which is better for C# architecture validation?

Accepted Answer

ArchUnitNET integrates directly with unit tests using a fluent API for custom rules, ideal for automated compliance checks. NDepend offers broader static analysis with a graphical interface but may be more complex and less focused on test-driven architecture validation.

Question 3

Does ArchUnitNET work with .NET 5 and above?

Accepted Answer

Yes, ArchUnitNET is compatible with .NET Core, .NET 5, 6, and later versions, as it analyzes compiled assemblies regardless of the target framework, making it suitable for modern .NET development.

Question 4

How to test layer dependencies in a clean architecture with ArchUnitNET?

Accepted Answer

Define rules using the fluent API to specify that classes in one layer (e.g., Application) should not depend on classes in another layer (e.g., Infrastructure), and integrate these into your test suite to enforce separation of concerns automatically.

Question 5

What are common pitfalls when using ArchUnitNET?

Accepted Answer

Common issues include not running tests in Debug configuration, leading to inaccurate results, and overlooking dynamic dependencies that aren't captured by static analysis. Also, maintaining many rules can become cumbersome as the codebase grows.

Question 6

Can ArchUnitNET enforce naming conventions across a solution?

Accepted Answer

Yes, you can create rules that check class or interface names against patterns, such as requiring interfaces to start with 'I' using methods like HaveNameContaining(), and integrate these into your test suite for consistent naming.
