Test attachments are not appearing in the VS Test Explorer

Test attachments are not appearing in the VS Test Explorer.

When I use the API TestContext.AddTestAttachement I'm expecting to see these attachments appear in the VS Test Explorer like this:

But unfortunately the attachments are not shown.

• NUnit 3.7.1 and NUnit3TestAdapter 3.8
• Visual Studio 2017 15.2 26430.16
• Repro: in a new Class Library project add the NUnit and NUnit3TestAdapter packages. Then add this code and run the test from the test explorer.

using NUnit.Framework;
using System.IO;

namespace ClassLibrary1
{
    [TestFixture]
    public class Class1
    {
        [Test]
        public void Method1()
        {
            TestContext.AddTestAttachment(Path.GetTempFileName());
        }
    }
}

Running it using the console shows the attachment is in the TestResult.xml:

    <test-suite type="TestSuite" id="0-1003" name="ClassLibrary1" fullname="ClassLibrary1" runstate="Runnable" testcasecount="1" result="Passed" start-time="2017-08-02 16:11:28Z" end-time="2017-08-02 16:11:28Z" duration="0.025336" total="1" passed="1" failed="0" warnings="0" inconclusive="0" skipped="0" asserts="0">

Hmm, no repro on VS 2015. I don't have 2017 here to test it.

Just for the avoidance of any doubt - have you spotted you need to click the 'output' label to view the attachments?

On VS2015, the test initially displays as this:

And once you follow the 'output' link:

🤦‍♂️ ...how embarrassing. You are right, need to click output and then it can be seen in the resulting view.

😄 No problem!
