Test execution hangs when using [SetUpFixture] with NUnit 3.8.x

[jairbubbles]

It hangs with console runner (3.7) and also with R# (2017.2).

Here are the log files when using --labels:before:
nunit_3_8_1.txt
nunit_3_7.txt

When running in R# we see that tests from other namespace never start:

It seems related to public class AssemblySetup which has the attribute [SetUpFixture].

Hi @jairbubbles can you also provide the InternalTrace-files when you add verbose logging (i.e. --trace=Verbose).

It seems highly related to my namespaces not being clean.

In TeaBox.Macros.Test assembly I have two main namespaces being tested:

• TeaBox.Macros in wich AssemblySetup is a SetUpFixture
• TeaBox.Scripting

I I move tests from TeaBox.Scripting tests to TeaBox.Macros.Scripting it works correctly.

(I'll try to make a simple repro case)

[jairbubbles]

Here we go:
BugNUnit.zip
It's pretty straight forward, run all tests and observe that the test in the exotic namespace will never run:

(You need VS2017).

Great, nice example @jairbubbles. To save other's having to download - here's the repro. (I haven't tried it myself.)

There were some changes in this area for 3.8 which introduced a few problems we've been rooting out. My guess is the particular specific things about your case we haven't seen before are a combination of:

1. A SetUpFixture for only some of your tests.
2. No parallelization attributes at all.

using NUnit.Framework;

namespace BugNUnit
{
    [SetUpFixture]
    public class AssemblySetup
    {
        public AssemblySetup()
        {
        }
    }

    [TestFixture]
    public class TestInNamespace
    {
    }
}

namespace OtherNamespace
{
    [TestFixture]
    public class TestInAnotherNamespace
    {
    }
}

[jairbubbles]

I can confirm you that adding [Parallelizable] on of the test fixture does fix the issue too.

Assigning this to myself for now so we don't duplicate one another. I'm adding this as a case to the suite of parallelization tests I'm working on.
