Keen to use Moq in your .NET Core project (i.e. ASP.NET Core and XUnit)? Here’s how to get setup.
Moq is a mocking framework for .NET. If you’d like to learn more about Moq, check out their GitHub page.
Adding Moq in your Test Project
I’m assuming you have a test project using your favourite unit test framework such as XUnit, NUnit, MSTest, etc. I’m using XUnit.
Step 1: Add the Moq NuGet package
As of this writing, only the pre-release version supports .NET Core and the current version is 4.6.38-alpha
Install-Package Moq -prerelease
Step 2: Add TraceSource package
This is an important step – one that caused me a lot of pain. It’s required but not set as a dependency. Without it you will get IO File exceptions when you try to use a mocked object.
Install-Package System.Diagnostics.TraceSource -version 4.0.0
Complete project.json File
The following is a complete example of the project.json.
Note that this project.json belongs to a project running .NET Core 1.1, hence the netcoreapp1.1 entry.
