correct filename typo
rough tests for registration and diary question display
better name for survey test case
If it is the wrong week then we do not know what week it is
handle user finding errors for diary pages

if there is no token or we don't find the user then it's a problem
test that it looks like we get the right week

still doesn't handle only showing diary for Thursday -> Sunday
if the user started more than 12 weeks ago then don't show diary
basic test to make sure diary entries are recorded
create SurveyDate class for date functions

this is largely so we can mock something for testing
the diary questions are only available thursday to sunday
use SurveyDate object for determing start date
