I tried fixing it but to no avail. I'm pretty sure I followed the tutorial. This happened in chapter 8 of The Rails Tutorial.
Here is the error when i run bundle exec rake test

Thanks for your help.
It looks like the first two errors are in your session_helper: your setup defines @user = user(:microte).
Not sure about the errors in the remembering tests are; the tests you've shared appear to be fine. I suggest you compare the code changes against what's in the tutorial to see what the cause of these errors are.
