SignalR is part of the .NET Core framework that allows for real-time communication between a server and any number of clients. The traditional example is a JavaScript client that can receive updates directly from a web server asynchronously, but you can also connect to a SignalR hub with a C# client. via GIPHY HubConnectionBuilder To … [Read more…]
Last week I wrote about bit fields and how they can be used to easily track boolean values. Unit testing is pretty important to me, because I make mistakes a lot. By writing tests, I can have a little bit of confidence in the code that I wrote. via GIPHY Bit Fields Knowing how bit … [Read more…]
Every now and again I find it necessary to set up the request body manually (as opposed to using the [FromBody] tag). In the controller you can read from the request body easily enough: via GIPHY Testing How do you test this? Normally I would just create a controller, call the method, and check the … [Read more…]
Recently I had a situation where I had a class and interface to make a generic service which would do something based on whatever type is provided. (Obviously, it was not so contrived…) These would then get injected to other classes to be used as necessary: Which works fine… as long as you remember to … [Read more…]
XUnit has some cool stuff like Theory, which lets you write multiple test cases to run against the same test code. This lets you test multiple paths with different inputs without having to write multiple tests. This can save you a lot of time as you can cover a lot of ground with a single … [Read more…]
Imagine that you have a NuGet package containing a bunch of static strings. These fields are intended to be used instead of magic strings, making it so anything that takes a dependency on this NuGet package will all be on the same page about these unique keys. Now suppose that these keys also represent the … [Read more…]
In a C# console application, you can change the color of the text emitted by Console.WriteLine by setting Console.ForegroundColor and Console.BackgroundColor. It’s pretty straightforward, but if you want to make the output have different colors to denote different things, its kind of cumbersome to have to set the color and then write the output, and … [Read more…]
Recently I was trying to write a unit test testing to see if one object was equal to another. The objects themselves were simple, just a collection of built-in types, so it should be easy to test. .Equals However, since I didn’t implement .Equals, C# doesn’t natively know how to check if the objects are … [Read more…]
