Environment data

dotnet --info output:

.NET Command Line Tools (1.0.4)

Product Information:
 Version:            1.0.4

Runtime Environment:
 OS Name:     debian
 OS Version:  8
 OS Platform: Linux
 RID:         debian.8-x64
 Base Path:   /usr/share/dotnet/sdk/1.0.4

VS Code version: C# Extension version: 1.12.1

omnisharp-vscode: 1.10.0-beta2

Steps to reproduce

Here is a repo which exactly reproduces this https://github.com/tomzo/bug-nunit-no-output-vscode

Just run

dotnet restore
dotnet test DefaultTests/DefaultTests.csproj

Then try the same in vscode by clicking on run test on one of the tests.

Expected behavior

There are tests which are failingand there is standard output printed in one of the tests.

[Test]
        public void Test1()
        {
			new Class1 ();
            Console.WriteLine("Test body running..");
        }

		[Test]
        public void Test2()
        {
            Assert.AreEqual(2,26);
        }

I would expect to see both the stdout and especially failed asserts from nunit test cases.

Actual behavior

In VsCode .NET Test Log output just counts the failed tests

The output when running with dotnet is fine:
