Verify that, if the input
data is valid, the
application block can
log messages to the
MsmqTraceListener
trace listener.
Passed The following test uses Message Queuing and verifies that
the message is logged to the queue. Similar tests exist to
verify that all the other trace listeners are supported by the
application block.
[TestMethod]
public void LogToMsmq()
{
using (MessageQueue queue = new MessageQueue(@".\
Private$\EntlibTest"))
{
queue.Purge();
queue.Formatter = new XmlMessageFormatter();
string[] types = { "System.String" };
((XmlMessageFormatter)queue.Formatter).Target-
TypeNames = types;
Logger.Write(new LogEntry("To test Msmq listener
using Logger facade","MsmqCategory",1,1,TraceEven
tType.Critical,"",null));
Message message = queue.Receive(new TimeSpan(0,0,5));
Assert.IsNotNull(message);
string content = (string) message.Body;
Assert.IsTrue(content.
Contains("To test Msmq listener using Logger facade"));
}
}
Verify that trace
listeners can be created
directly, without
using a configuration
source.
Passed
The following test uses a constructor to create a database
listener and a custom object that is logged to the database.
[TestMethod]
public void LogToDbListenerUsingCustomObject()
{
FormattedDatabaseTraceListener listener = new
FormattedDatabaseTraceListener(DatabaseFactory.
CreateDatabase("SqlServer"), "WriteLog", "AddCategory",
new TextFormatter());
listener.TraceData(null, "Error : ",
TraceEventType.Critical, 1, new MyObject());
Database db = DatabaseFactory.CreateDatabase("Sq
lServer");
DbCommand command = db.GetSqlStringCommand("SELEC
T TOP 1 Message FROM Log ORDER BY LogId DESC");
string messageContents = Convert.ToString(db.
ExecuteScalar(command));
Assert.AreEqual(messageContents,
"CustomClasses.MyObject");
}
