I would suggest to use some multi-thread safe container rather than a simple array to store the LogRecord. For instance - a CopyOnWriteArrayList - or something like that. Also you may want to harden the test by allowing for the possibility that some other logging might have occurred, and search the list for the record you expect rather than assuming it will be the first and only one.
Otherwise looks good!
