WireMock.NET 😮

WireMock.NET is a .NET library for stubbing and mocking HTTP services. With WireMock.NET, you can define the expected responses for particular requests, and the library will intercept and manage those requests for you. ✔️

This allows for easy testing of the code that makes HTTP requests, without having to rely on the actual external service being available and without hacking HttpClient. 🆒

Sample code snippet:

[Test]
public async Task sample_WireMock_usage()
{
  // Setup WireMock.Net server
  using var wireMock = WireMockServer.StartWithAdminInterface(port: 1080, ssl: false);
  
  // Setup WebApplicationFactory
  await using var appFactory = new WebApplicationFactory<Program>().WithWebHostBuilder(builder =>
  {
    builder.ConfigureAppConfiguration(configurationBuilder =>
    {
      // Override downstream service addresses pointing to WireMock address
      configurationBuilder.AddInMemoryCollection(new Dictionary<string, string>
      {
        ["ExternalServices:WeatherService"] = "http://localhost:1080"
      });
    });
  });

  // Prepare stub for outgoing request
  wireMock
    .Given(
        Request.Create()
            .WithPath("/api/v1.0/weather")
            .WithParam("lat", "10.99")
            .WithParam("lon", "44.34")
            .UsingGet()
    )
    .RespondWith(
        Response.Create()
            .WithStatusCode(200)
            .WithHeader("Content-Type", "application/json; charset=utf-8")
            .WithBodyAsJson(new
            {
                temp = 298.48,
                feels_like = 298.74,
                temp_min = 297.56,
                temp_max = 300.05,
                pressure = 1015,
                humidity = 64
            })
    );

    // Automate tested app
}

Check out new C# 12 preview features! ⚡️

Three new features for C# 12 😮 :

1️⃣- Primary constructors for non-record classes and structs :

public class Student(int id, string name, IEnumerable<decimal> grades)
{
    public Student(int id, string name) : this(id, name, Enumerable.Empty<decimal>()) { }
    public int Id => id;
    public string Name { get; set; } = name.Trim();
    public decimal GPA => grades.Any() ? grades.Average() : 4.0m;
}

2️⃣- Using aliases for any type:

using Measurement = (string, int);

public void F(Measurement x)
{ }

3️⃣- Default values for lambda expression parameters:
var addWithDefault = (int addTo = 2) => addTo + 1;
addWithDefault(); // 3
addWithDefault(5); // 6

.NET 8 - Keyed service dependency injection container support 🔝

Keyed services are useful when you have an interface/service with multiple implementations that you want to use in your app. What's more, you need to use each of those implementations in different places in your app. ☄️

Sample:
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddKeyedSingleton<INotificationService, SmsNotificationService>("sms");
builder.Services.AddKeyedSingleton<INotificationService, EmailNotificationService>("email");
builder.Services.AddKeyedSingleton<INotificationService, PushNotificationService>("push");

Bloom Filters 🆒

Imagine ensuring web safety by identifying malicious links without storing massive data. Traditional methods involve keeping a huge list of bad links, consuming substantial storage and bandwidth. Enter Bloom Filters - a genius method allowing us to significantly reduce storage needs (up to 82% smaller) with a minimal error rate. 👾

For instance, instead of a 20MB list for 1,000,000 links, a Bloom Filter achieves this with just 3.59MB, accepting a tiny error chance (0.0001%). Even more impressive, with a 0.1% error tolerance, the size shrinks to 1.8MB. This technique was even utilized by Google Chrome until 2012. ✔️

Bloom Filters offer a balance between efficiency and accuracy. For critical checks, it pairs with a database API for zero false positives. A practical, space-saving solution for modern web browsers! ⚡️
