Simple Example (xUnit)

using Microsoft.Extensions.Logging;
using Xunit;
namespace Xunit.Abstractions;
// This class may be used as the base class for test classes.
public abstract class XunitTestBase
{
 private readonly ITestOutputHelper Output;
 protected readonly ILoggerFactory LogFactory;
 protected readonly ILogger Logger;
 protected void Write(string format, params object[] args) =>
 Output.WriteLine(string.Format(format, args) + Environment.NewLine);
 protected XunitTestBase(ITestOutputHelper output, LogLevel logLevel = LogLevel.Debug, string name = "Test")
 {
 Output = output;
 LogFactory = LoggerFactory.Create(builder => builder
 .AddMXLogger(output.WriteLine)
 .SetMinimumLevel(logLevel));
 Logger = LogFactory.CreateLogger(name);
 }
}

using Microsoft.Extensions.Logging;
using Xunit;
using Xunit.Abstractions;
namespace YourNamespace;
public class SimpleExample : XunitTestBase
{
 public SimpleExample(ITestOutputHelper output) : base(output) { }
 [Fact]
 public void Test()
 {

Dependency Injection Example (xUnit)

using Microsoft.Extensions.Logging;
using Microsoft.Extensions.DependencyInjection;
using Xunit;
using Xunit.Abstractions;
public class MyComponent
{
 private readonly ILogger Logger;
 
 public MyComponent(ILogger<MyComponent> logger)
 {
 Logger = logger;
 }
 
 public void Run()
 {
 Logger.LogCritical("Message");
 ...
 } 
}
public class DependencyInjectionTest
{
 private readonly MyComponent MyComponent;
 public DependencyInjectionTest(ITestOutputHelper output)
 {
 MyComponent = new ServiceCollection()
 .AddTransient<MyComponent>()
 .AddLogging(builder => builder
 .AddMXLogger(output.WriteLine)
 .SetMinimumLevel(LogLevel.Debug))
 .BuildServiceProvider()
 .GetRequiredService<MyComponent>();
 }
 [Fact]
 public void Test()
 {
 MyComponent.Run();
 ...
 }
}

Crit: MyNamespace.MyComponent
