MartinCostello.Logging.XUnit provides extensions to hook into the ILogger infrastructure to output logs from your xunit tests to the test output.
ℹ️ This library is designed for the Microsoft logging implementation of
ILoggerFactory. For other logging implementations, such as Serilog, consider using packages such as Serilog.Sinks.XUnit instead.
To install the library from NuGet using the .NET SDK run:
dotnet add package MartinCostello.Logging.XUnit
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Xunit;
using Xunit.Abstractions;
namespace MyApp.Calculator;
public class CalculatorTests(ITestOutputHelper outputHelper)
{
[Fact]
public void Calculator_Sums_Two_Integers()
{
// Arrange
using var serviceProvider = new ServiceCollection()
.AddLogging((builder) => builder.AddXUnit(outputHelper))
.AddSingleton<Calculator>()
.BuildServiceProvider();
var calculator = services.GetRequiredService<Calculator>();
// Act
int actual = calculator.Sum(1, 2);
// Assert
Assert.AreEqual(3, actual);
}
}
public sealed class Calculator(ILogger<Calculator> logger)
{
public int Sum(int x, int y)
{
int sum = x + y;
logger.LogInformation("The sum of {x} and {y} is {sum}.", x, y, sum);
return sum;
}
