ILogger logger = XUnitLogger.CreateLogger();
ILogger<MyType> logger = XUnitLogger.CreateLogger<MyType>();

If you are using a WebApplicationFactory:

public class UnitTest1(ITestOutputHelper testOutputHelper)
{
    [Fact]
    public async Task Test1()
    {
        using var factory = new WebApplicationFactory<Program>()
            .WithWebHostBuilder(builder =>
            {
                builder.ConfigureLogging(builder =>
                {
                    // You can override the logging configuration if needed
                    //builder.SetMinimumLevel(LogLevel.Trace);
                    //builder.AddFilter(_ => true);

                    // Register the xUnit logger provider
                    builder.Services.AddSingleton<ILoggerProvider>(new XUnitLoggerProvider(testOutputHelper, appendScope: false));
                });
            });
    }
}
