Serilog.Sinks.TestCorrelator 
A Serilog sink that correlates log events with the code that produced them, enabling unit testing of log output.
Usage
Just create a logger that writes or audits to the TestCorrelator.
Log.Logger = new LoggerConfiguration().WriteTo.TestCorrelator().CreateLogger();Then wrap the code that you would like to monitor with a context and get the log events emitted within that context using the TestCorrelator.
using (TestCorrelator.CreateContext())
{
Log.Information("My log message!");
TestCorrelator.GetLogEventsFromCurrentContext()
.Should().ContainSingle()
.Which.MessageTemplate.Text
.Should().Be("My log message!");
}You can also get a stream of log events as an observable, which can be useful for testing long running or asynchronous tasks.
using (TestCorrelator.CreateContext())
{
TestCorrelator.GetLogEventStreamFromCurrentContext()
.Subscribe(logEvent => logEvent.MessageTemplate.Text.Should().Be("My log message!"));
Log.Information("My log message!");
}For more examples check out the unit tests!
