Which memory test, which tool, and which tutorial? I'm presuming that you're using the built in memory tester - and it should've given you a notice if it passed the test or if it found any problems. If you didn't get a message, then I'd suspect that the test terminated abnormally - so you'll have to run the test and see if you can get a message from it (or see when it terminates). This'll involve a lot of boring, staring at the screen - but I've found not evidence of a log file or results page that will be displayed.
Here's a link to the BC tutorial on the memory test:
