BenchmarkDotNet Logger for Xunit

XunitTestOutputLogger.cs

namespace MartinCostello
{
    using BenchmarkDotNet.Loggers;
    using Xunit.Abstractions;

    /// <summary>
    /// A class that writes output to the test output for Xunit. This class cannot be inherited.
    /// </summary>
    public sealed class XunitTestOutputLogger : ILogger
    {
        /// <summary>
        /// The <see cref="ITestOutputHelper"/> in use. This field is read-only.
        /// </summary>
        private readonly ITestOutputHelper _helper;

        /// <summary>
        /// Initializes a new instance of the <see cref="XunitTestOutputLogger"/> class.
        /// </summary>
        /// <param name="helper">The <see cref="ITestOutputHelper"/> to use.</param>
        public XunitTestOutputLogger(ITestOutputHelper helper)
        {
            _helper = helper;
        }

        /// <inheritdoc />
        public void Write(LogKind logKind, string format, params object[] args)
        {
            _helper.WriteLine(format, args);
        }
    }
}

Obviously requires you to have BenchmarkDotNet and Xunit first:

Install-Package BenchmarkDotNet
Install-Package Xunit
