[MTP] Cannot stop running tests if parallel testing used
using System;
using System.Linq;
using System.Threading.Tasks;
using NUnit.Framework;
// without it, process stops
[assembly: Parallelizable(ParallelScope.Children)]
internal sealed class Tests
{
private static readonly int[] _cases = [.. Enumerable.Range(1, 100)];
[TestCaseSource(nameof(_cases))]
public async Task Test(int pause)
{
await Task.Delay(TimeSpan.FromSeconds(pause % 10));
}
}
When I want to stop my tests by pressing Ctrl-C in console, test process exists only when tests are not executed in parallel. For parallel execution it hangs and I need to terminate process

Canceling the test session...
NUnit Adapter 5.1.0.0: Test execution complete
Test run summary: Aborted - MTPIssues.dll (net9.0|x64)
total: 3
failed: 0
succeeded: 3
skipped: 0
duration: 8s 119ms
Summary is printed, but process is still running (unterminated rogue thread without IsBackground=true?)
Issue mentions that Ctrl+C works when parallelization is disabled, but not with enabled. This is likely suggesting an NUnit bug and probably unlikely to be an issue on MTP side as cancellation is most likely propagated to NUnit.
@MaceWindu So this works without MTP, and not with MTP ?
Do you have a csproj for this?
Attached. It works without parallelzation, but not with. In vstest mode it also works.
