Running a specific test with .NET Core and NUnit

1 minute read

I converted the Unit tests for the Auth0.NET SDK to .NET Core. Currently the unit testing framework being used is NUnit, and NUnit 3 comes with a test runner for .NET Core.

You can make use of it by configuring your project.json as follows:

    "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 configuration above is current as of the writing of this blog post. Please refer to the NUnit 3 Test Runner for .NET Core GitHub Page to obtain the must up to date informaton on how to configure it.

With this in place you can easily run your unit tests from the command line by simply running the command

dotnet test

This will however run all the tests in a particular assembly (except for the Explicit ones), but what if you want to run only a specific unit test?

Well for that you can refer to the documentation for the Console Command Line. According to that documentation, one of the parameters you can pass to the Console Runner is --test, which allows you to specify a comma-separated list of names of test to run.

You can also pass this --test parameter to the dotnet test runner, which it seems is then passing it on to the NUnit .NET Core Test runner. So for example, if I wanted to run the unit test Auth0.ManagementApi.IntegrationTests.UsersTests.Test_users_crud_sequence, I could execute the following command:

dotnet test --test Auth0.ManagementApi.IntegrationTests.UsersTests.Test_users_crud_sequence

And that will then only run that particular unit test:
