Enigmatry.Entry.SmartEnums.VerifyTests 9.1.1-preview.5

Smart Enums VerifyTests

A library that provides testing utilities for Smart Enums using the Verify testing approach, allowing for snapshot testing of Smart Enum behaviors and serialization.

Intended Usage

Use this library when you need to write tests for Smart Enum types using the Verify snapshot testing approach. It helps validate that your Smart Enums behave consistently and serialize correctly.

Installation

Add the package to your project:

dotnet add package Enigmatry.Entry.SmartEnums.VerifyTests

Usage Example

using Enigmatry.Entry.SmartEnums;
using Enigmatry.Entry.SmartEnums.VerifyTests;
using System.Reflection;
using Argon;
using NUnit.Framework;
using VerifyNUnit;

namespace YourProject.Tests
{
    [TestFixture]
    public class ProductCategoryTests

        private VerifySettings verifySettings;
        
        [SetUp]
        public void Setup()
        {
            // Create and configure VerifySettings for tests
            verifySettings = new VerifySettings();
            
            // Register SmartEnum converters for the Argon JSON serializer used by VerifyTests
            var converters = new List<JsonConverter>();
            converters.EntryAddSmartEnumJsonConverters(new[] { Assembly.GetExecutingAssembly() });
            
            // Add the converters to the serialization pipeline
            verifySettings.UseJsonSerializerSettings(settings => 
            {
                foreach (var converter in converters)
                {
