Unit Tests Not Appearing

Question

I'm using Visual Studio Express 2012 on the Windows 8 Release Preview and I can't seem to get my unit tests to appear in the test explorer.

I have a class called TestApp.Entity, and TestApp.EntityTest...

Here is my code:

namespace TestApp.Entity.Test
{
    using System;
    using System.Net.Http;
    using Microsoft.VisualStudio.TestPlatform.UnitTestFramework;
    using TestApp.Domain;

    [TestClass]
    public class EntityTests
    {
        [TestMethod]
        public async void TestObject1Deserialize()
        {
            Uri agencyUri = new Uri("*removed*");
            HttpClient httpClient = new HttpClient();
            HttpResponseMessage response = await httpClient.GetAsync(agencyUri);

            string responseBodyAsText = await response.Content.ReadAsStringAsync();
            List<Agency> agencyList = Deserializers.AgencyDeserialize(responseBodyAsText);

            CollectionAssert.Contains(agencyList, new Agency() { Tag = "*removed*", Title = "*removed*", ShortTitle = "", RegionTitle = "*removed*" });
        }

    }
}

I assume that's all I needed to do, but they still don't appear in the test explorer. Any advice would be helpful.

Answer 1

As per Stephen Cleary, "you need to make your unit tests async Task instead of async void for them to work correctly".

This fixed the problem and the tests appeared. It's odd that no errors appeared when I used void, but now I know. Thank you!

Answer 2

I have Visual Studio 2012 and i couldn't see the Tests in Test Explorer,

So I installed the following: NUnit Test Adapter

That fixed the issue for me !

Answer 3

Do a rebuild all on the application, including any projects that contain test classes and test methods. They should appear in Test Explorer soon after.
