Dot Net Core Unit Testing using Xunit -> How to write initialization function for class

I've started work on Unit Testing in Dot Net Core 2.0. I've written a class to Unit Test controller class of my Web API.

Please find below the code of my Unit Test Class

public class ArticlesControllerTests
{
    private ArticlesController _articlesController;

    private Mock<IArticleRepository> _articleRepositoryMock = new Mock<IArticleRepository>();

    public ArticlesControllerTests()
    {
        _articlesController = new ArticlesController(_articleRepositoryMock.Object);
    }

    [ClassInitialize]
    public static void Init()
    {
        AutoMapperInit.Initialize();
    }
}

I want to write Init function that will call once and initialize AutoMapper configurations. But [ClassInitialize] is not there. I've searched online but I was not able to find that attribute.

What should I do to make it work for Dot Net Core 2.0.

Using a static constructor on the test class should provide the same behavior

public class ArticlesControllerTests {
    private ArticlesController _articlesController;

    private Mock<IArticleRepository> _articleRepositoryMock = new Mock<IArticleRepository>();

    public ArticlesControllerTests() {
        _articlesController = new ArticlesController(_articleRepositoryMock.Object);
    }

    static ArticlesControllerTests() { //<-- static constructor
        AutoMapperInit.Initialize();
    }

    //...
}

the static constructor will call once and initialize AutoMapper configurations
