Moq VS Shouldly

In terms of mocking there are several frameworks you can use, but I've mainly relied on Moq and NSubstitute. Within this demo, I'm going to use NSubstitute as I've found it a little easier to use.

Or you just run into bullshit like https://github.com/Moq/moq4/issues/173

Now to the real benefit of DI: If you are testing a method in your application that calls the ReservationRepository.GetReservation() method, you can use a library like Moq to simply "mock" a class that uses the IReservationRepository interface and define the return result of the GetReservation() method. Pass the mocked class into the constructor of the class you are testing.

Both projects use similar testing infrastructure. I write unit tests in C# using XUnit.net. I frequently use mock objects in testing, and MOQ is my tool of choice. I utilize continuous testing and coverage analysis through Rider. I do not have specific objectives for code coverage. When writing complicated algorithms, I frequently shoot for 100% coverage of the algorithm. I test simple properties inconsistently, and frequently do not test guard clauses.

But the reality is that I don't really write my tests with it. Toss on the MSTest attributes as needed of course. But all the testing code itself is FluentAssertions with a bit of Moq. (Though I find rarely need to use Moq/mocking anymore -- scandalous, I know.)

On a side note, something I would highly recommend NOT doing is using the built in assertion types for any of the test adapters. Without a doubt the hardest part of switching unit test frameworks is having to fix all your assertions which is why we use 3rd party assertions. The built-in assertions also tend to not be very feature rich and don't have the most helpful messages. We personally use FluentAssertions, but there are other options such as Shoudly or Should. I highly recommend picking one of them over the built in assertions. You will thank yourself later :)

Shouldly - More "fluent" way of writing assertions that I tend to like more personally. Example:

I use NUnit and Shoudly.
