I would join those who would like incremental logging. I actually wrote to this mailing list quite a while ago, asking if it was possible to flush the log file after each test, but it got lost or something. So I ended up implementing my own logging, with only the basic information I needed. It is still XML with all its advantages. I can't remember exactly now, but I think I overwrite it instead of appending. No clue about parallel running though - never used it or even thought it was possible :) However IMHO running two fixtures in parallel and need for incremental logging is equally common/incommon. Well, but even if I am not really sure how running tests in parallel works, I am quite sure that there's not so much overhead for implementing logging having it in mind. Maybe having separate 
 log files, maybe merging them afterwards or maybe just synchronizing writing to the file.

My main reason for incremental logging was one kind of tests crashing Nunit randomly, which I could not find a way to resolve. So I would just rerun the tests from where they crashed if it happened.

Any other format for log files is acceptable for me, as long as they can be viewed comfortably (as xml is with xls). NUnit custom appendable format may be used with Nunit's own viewer, for example.

Best regards,
Aiste
