Next we are going to setup an NUnit test project and using .NET WebApplicationFactory we will call the API endpoint and parse the resonse as an products array and compare the actual response to an expected json file embedded in our source code.…

Moq vs. NSubstitute vs. FakeItEasy

Today I though I would do some syntax comparison between a few of the biggest Mocking Framework in .NET: Moq, NSubstitute and FakeItEasy. Although these framework have slight functional differences they pretty much do the same thing but in different syntax and lingo.…

Loose vs. Strict mocking behaviour

I thought I would demonstrate the difference between Loose and Strict mocking behaviour when using the Moq Framework. By default when you create a new mock and don't specify a MockBehaviour it will be assigned MockBehaviour.Default, which equals to MockBehaviour.Loose.…

How to set TransactionScope timeout in code, application and server wide

The other day we got a bunch of these transaction exceptions logged on some of our production servers: "The operation is not valid for the state of the transaction".

Loading this assembly would produce a different grant set from other instances

The other day one of our legacy applications threw this strange error during a production deploy: "Loading this assembly would produce a different grant set from other instances". This .NET 4.6 application is a load balanced SOAP API and strangely this only occured on 1 of the 3 frontend servers so when browsing the frontend it initially seems healty but every other random request would fail and show this error.…

5th year teaching .NET Testing at local university college YRGO

Today I had the privilege of lecturing for the 5th year at Yrgo University college on the subject of .NET Testing. As always, the goal has been to give students a positive impression of testing early in their career and that writing tests is not something you "should" or "must" do but something you WANT to do because it is a fun and challenging part of being a developer.…

Logging HttpRequests using DelegatingHandler with a named HttpClient and HttpMessageHandlers in Umbraco

Using TestRunParameters in your NUnit tests using .runsettings

I've been getting a lot of traffic lately related to the google search phrase "nunit runsettings example" which at the moment leads to this blogpost I wrote on how to use Playwright with NUnit, which doesn't really cover how to set up .runsettings but rather how you can toggle headless mode in Playwright (totally different topic). So I thought I would share a little tutorial on how you can set up a new NUnit project and use .runsettings and TestRunParameters in your tests.…

C# 8.0 Default interface methods in under 60 seconds!

Integrating Papertrail logging in a .NET (NLog) application

Testing the untestable with the Adapter Design Pattern

During my session at last weeks Codegarden on ‘Getting started with Unit Testing in Umbraco’ I got a really good question in the Q&A afterwards, and I thought I would share the question and elaborate on my answer: -“What tips do you have for mocking services that are overly complex or have lots of dependencies that can't be null?”…

Showing a maintenance banner on your Umbraco site

Something we do for most of our sites is setting what we call a deploy flag during our deployments and then have our frontend render a maintenance banner at the top of the website. By showing a maintenance banner we can inform the visitor that at the moment we are performing planned maintenance and that they might experience disturbances.…

Starting to Unit Test: Not as Hard as You Think

I thought I would share a recommendation for a really great book that I think anyone who is new to Unit Testing should read: Starting to Unit Test: Not as Hard as You Think by Erik Deitrich. I read this book many years ago but I remember it to this day because it was an eye opener to what Unit Testing essentially is.…

Parallelism: NUnit vs. xUnit

Running your tests in parallel can significantly improve the speed of your test runs, but it could give you occasional problems especially if you're working on static implementations. Also turns out that depending on which testing framework you're using parallelism might be handled differently.…
