Testing asp.net core 2.0 project with Xunit how to test httpget

Question

I've got a asp.net core 2.0 project I'm building in Visual Studio 2017. I'm learning the ropes with testing a asp.net core project but I'm wondering how to test the HHTPGET methods within my controller.
Below is my initial controller.

public class ValuesController : Controller
{
    private Config MyConfig { get; }

    private Solr Solr { get; }

    private Voyager Voyager { get; }

    private Messages Messages { get; }

    public ValuesController(Config config, Solr solr, Voyager voyager, Messages messages)
    {
        MyConfig = config;
        Solr = solr;
        Voyager = voyager;
        Messages = messages;
    }

    // GET api/values
    [HttpGet]
    [Route("/api/[Controller]")]
    public IEnumerable<string> Get()
    {
        string version = ".NET Framework: " + Environment.Version.ToString();
        string vers = "ASP.NET Core Framework: " + typeof(Controller).Assembly.GetName().Version.ToString();
        return new string[] { version, vers };
    }

    [HttpGet]
    [Route("/api/[Controller]/config")]
    public JsonResult GetConfig()
    {
        return new JsonResult(MyConfig);
    }

    [HttpGet]
    [Route("/api/[Controller]/solr")]
    public JsonResult GetSolr()
    {
        return new JsonResult(Solr);
    }

    [HttpGet]
    [Route("/api/[Controller]/voyager")]
    public JsonResult GetVoyager()
    {
        return new JsonResult(Voyager);
    }

    [HttpGet]
    [Route("/api/[Controller]/messages")]
    public JsonResult GetMessages()
    {
        return new JsonResult(Messages);
    }

Just wondering if someone could give an example of how to test these routes or HTTPGets...

for each get method you wanna test what will be the result it is returning ?? — RJ-, Oct 11 '17 at 22:11
@RJ- To start with I'd like to test that those don't return errors. Something basic. — yams, Oct 11 '17 at 22:17

So I found that the first step is to setup a mock connection that is somewhat generic so I created a method to mock the connection to a server via the method below.

    private CollectionsController SetupController()
    {
        if (controller != null)
        {
            controller = null;
        }
        if (controllerContext != null)
        {
            controllerContext = null;
        }
        controller = new CollectionsController();
        controller.ControllerContext = new ControllerContext();
        controllerContext = controller.ControllerContext;
        controllerContext.HttpContext = new DefaultHttpContext();
        //The header below is generic don't really care what the device id is
        controllerContext.HttpContext.Request.Headers["device-id"] = "20317";

    }

Then as an example I've set up a test below that just checks the status code and asserts the object returning from the controller is not null.

    [Fact]
    public void TestPostCollectionName()
    {
        valData = new ValData();
        valData.value = "NewObject";
        controller = SetupController();
        var results = controller.PostCollectionName(valData, testCollecName);
        Assert.NotNull(results);
        Assert.True(controllerContext.HttpContext.Response.StatusCode == 200);

    }

Thank you, you saved me so much time – r.mirzojonov Jul 09 '18 at 09:00 — r.mirzojonov, Jul 09 '18 at 09:00
