✅ Where does BenchmarkDotNet save my files?

I can run the following successfully but I cannot find where the files A.txt and B.txt are saved. Where are they saved?

using BenchmarkDotNet.Attributes;
using BenchmarkDotNet.Running;

BenchmarkRunner.Run<MyBenchmark>();


[MemoryDiagnoser]
public class MyBenchmark
{
    Guid Id = Guid.NewGuid();

    StreamWriter writerA = null!;
    StreamWriter writerB = null!;

    [GlobalSetup]
    public void GlobalSetup()
    {
        writerA = new("A.txt");
        writerB = new("B.txt");
    }

    [GlobalCleanup]
    public void GlobalCleanup()
    {
        writerA?.Dispose();
        writerB?.Dispose();
    }

    [Benchmark]
    public async Task A() => await writerA.WriteLineAsync(Id.ToString());

    [Benchmark]
    public async Task B() => await writerB.WriteLineAsync(Id.ToString());
}

using BenchmarkDotNet.Attributes;
using BenchmarkDotNet.Running;

BenchmarkRunner.Run<MyBenchmark>();

They are in a folder named BenchmarkDotNet.Artifacts\results inside the bin folder.

No. There are no A.txt and B.txt there.

Its a single text file for the class., not per test.

try and chuck in Console.WriteLine(Path.GetFullPath("A.txt"); after it's created probably gets put in a temporary folder that gets cleaned up after the run
