Every year I sign up to write a C# Advent post, and every year I wait until the last minute to do it.

I have just under 8 hours to get it done. Thankfully, the writing is coming easy today.

Inline Snapshot testing in .NET #csadvent #dotnet https://www.meziantou.net/inline-snapshot-testing-in-dotnet.htm?utm_medium=social&utm_source=mastodon

Inline Snapshot testing in .NET - Gérald Barré

In this post, I describe how to use Inline Snapshot testing in .NET. Inline Snapshot testing is a technique that allows you to write tests that assert the output of a method or function. The output is stored in a snapshot file. The next time the test is run, the output is compared to the snapshot file. If the output is different, the test fails. If the output is the same, the test passes."

Looking for a method to synchronize your lists of strings, integers, or even complex objects? In this post, I will explore an efficient syncing algorithm and demonstrate how it can be applied with .NET 8.0 features. This will enable you to easily keep your data in sync. Don't miss out on this valuable information! #aspnet #aspnetcore #csadvent
