NUnit 3 Test Runner for .NET Core


This project is deprecated. The test adapter API changed when .NET Core switched from project.json to the new csproj format. For newer .NET Core and .NET Standard projects, use the NUnit 3 Visual Studio Test adapter to run tests at the command line using dotnet test, in CI or in Visual Studio.

For more information on how to test .NET Core, see the .NET Core/.NET Standard documentation.

If you are reporting issues, we are no longer making updates to this project or the use of dotnet-test-nunit and project.json. Issues should be reported against the NUnit 3 Visual Studio Test adapter.

Build status Travis Build Status

dotnet-test-nunit is the unit test runner for .NET Core for running unit tests with NUnit 3.


dotnet-test-nunit is still an alpha release, so you need to select show prereleases if you are using Visual Studio.

Your project.json in your test project should look like the following;


    "version": "1.0.0-*",

    "dependencies": {
        "NUnit": "3.5.0",
        "dotnet-test-nunit": "3.4.0-beta-3"

    "testRunner": "nunit",

    "frameworks": {
        "netcoreapp1.0": {
            "imports": "portable-net45+win8",
            "dependencies": {
                "Microsoft.NETCore.App": {
                    "version": "1.0.0-*",
                    "type": "platform"

The lines of interest here are the dependency on dotnet-test-nunit. I have added "testRunner": "nunit" to specify NUnit 3 as the test adapter. I also had to add to the imports for both the test adapter and NUnit to resolve.

You can now run your tests using the Visual Studio Test Explorer, or by running dotnet test from the command line.

# Restore the NuGet packages
dotnet restore

# Run the unit tests in the current directory
dotnet test

# Run the unit tests in a different directory
dotnet test test/NUnitWithDotNetCoreRC2.Test


Note that the dotnet command line swallows blank lines and does not work with color. The NUnit test runner's output is in color, but you won't see it. These are known issues with the dotnet CLI and not an NUnit bug.


Deprecated test runner for .NET Core. For use with project.json only. For recent releases of .NET Core, use the NUnit 3 Visual Studio Adapter
