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! ⚡️

Introducing WireMock.NET: Master HTTP API Testing 🚀
WireMock.NET simulates HTTP API behaviors, enabling seamless integration and testing for developers.
👌 Ideal Use Cases:
• HTTP Dependencies Not Ready: Leap over the hurdle of incomplete HTTP APIs in microservice architectures by mimicking their behavior with WireMock.Net.
• Unit Testing HTTP-Dependent Classes: Test classes that rely on HTTP APIs as a cohesive unit, ensuring your code communicates effectively with the actual APIs.
• Integration/End-to-End Tests: Overcome the challenges of testing with external HTTP APIs—like variable data, slow responses, and network restrictions—by employing WireMock.Net for consistent and swift testing.
public class ExternalService(HttpClient httpClient)
{
public async Task<string> GetAsync()
{
var response = await httpClient.GetAsync("/ping");
response.EnsureSuccessStatusCode();
return await response.Content.ReadAsStringAsync();
}
}
public class ExternalServiceTests
{
[Fact]
public async Task GetAsync_WhenCalled_ReturnsString()
{
// Arrange
var fakeServer = WireMockServer.Start();
fakeServer
.Given(Request.Create().WithPath("/ping").UsingGet())
.RespondWith(Response.Create()
.WithStatusCode(200)
.WithBody("pong")
);
var fakeClient = fakeServer.CreateClient();
var externalService = new ExternalService(fakeClient);
// Act
var response = await externalService.GetAsync();

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:

{
builder.ConfigureAppConfiguration(configurationBuilder =>
{
// Override downstream service addresses pointing to WireMock address
configurationBuilder.AddInMemoryCollection(new Dictionary<string, string>
{

});
});
});
// Prepare stub for outgoing request
