Extensions.Logging.ListOfString
**Extensions.Logging.ListOfString** logs to a list of string so you can test your logging. If your components depend on an `ILogger<T>` use `Microsoft.Extensions.Logging.LoggerFactory` to make one: ``` ILoggerFactory factory=new LoggerFactory.AddProvider(new StringListLoggerProvider()) var logger= factory.CreateLogger<Test1>(); ...tests... ; StringListLogger.Instance .LoggedLines .ShouldContain(x=>x.Matches("kilroy was here")); ``` or ``` var loggedLines = new List<string>(); var logger= new LoggerFactory().AddStringListLogger(loggedLines).CreateLogger("Test2"); ...tests... ; loggedLines.ShouldContain(x=>x.Matches("kilroy was here too.")); ``` Or if a component only depends on an `ILogger`, it's much simpler. You don't need the factory or provider: ``` var uut = new MyComponent( StringListLogger.Instance ); ... tests ... StringListLogger.Instance .LoggedLines .ShouldContain(x=>x.Matches("kilroy was here")); ``` Or if you are using `Microsoft.Extensions.DependencyInjection` in your test suite then: ``` public StringListLogger Log = new(); ... ServiceCollection.AddLogging( lb => lb /* .AddConfiguration(Configuration.GetSection("Logging")) */ .AddProvider(new StringListLoggerProvider(Log)) /* .AddConsole() */ ); ...tests... Log.LoggedLines.ShouldContain(x=>x.Matches("kilroy was here")); ``` For tests running in parallel, each one creating a new LoggerFactory and LoggerProvider, don't rely on the shared StringListLogger.Instance. Follow the above example, passing a known instance to the LoggerProvider. This is for Microsoft.Extensions.Logging.Abstractions. For Serilog, see https://www.nuget.org/packages/Serilog.Sinks.ListOfString/ Part of https://www.nuget.org/packages/TestBase . *TestBase* gives you a flying start to unit testing with fluent assertions that are easy to extend, and tools for testing with dependencies on AspNetMvc, HttpClient, Ado.Net, Streams and Loggers.
