Seamlessly integrate Xunit's ITestOutputHelper with Microsoft.Extensions.Logging using netstandard2.1, net6.0, net7.0 and net8.0. Capture logs from any layer of your application and send them to your test output, making debugging and integration testing a breeze. With minimal configuration, you can monitor log messages, helping to ensure your application runs smoothly.

Installation

Options

Colored Log Levels

Microsoft Visual Studio does not support colored log levels. However, JetBrains Rider does support colored log levels. If you want to enable colored log levels, you can use LoggerColorBehavior enum. If the value is set to LoggerColorBehavior.Default, the log levels will be colored in JetBrains Rider and will not be colored in Microsoft Visual Studio.

Usage

For simple testing:

public class UnitTest
{
    public UnitTest(ITestOutputHelper outputHelper)
    {
        _loggerFactory = new LoggerFactory().AddXunit(outputHelper, options =>
        {
            // ... options
        });
    }
}

For testing with Microsoft.Extensions.DependencyInjection:

public class IntegrationTest : IXunitLogProvider
{
    public IntegrationTest(ITestOutputHelper outputHelper)
    {
        var serviceProvider = new ServiceCollection()
            .AddLogging()
            .AddXunitLogger(message => OnWriteLine?.Invoke(message), options => 
            {
                // ... options
            })
            .BuildServiceProvider();
        this.OnWriteLine += outputHelper.WriteLine;
    }

    public event Action<string> OnWriteLine;
}
