Hi,
Common practice is to write unit tests against known test data, rather than
against unknown production data.
That way you could compare the actual values returned.
When doing testing against unknown data you are limited to whatever extra
checks you can make:
* is the correct number of items returned
* do all of them contain count greater than 0
* are they all sorted in (alphabetical | count) order

Hi,all
The Item can be viewed by visitor, the viewed counter will be saved in
database table(e.g. Items table). So getPopularItems() is to get the
most viewed items, according to the viewed counter of items.
The problem is:
What should I check in test case for getPopularItems()?
Since getPopularItems() get most viewed items according to the viewed
counter, If I use this method again to get most viewed items in
testGetPopularItems() and check if these two collections(popular
items) are equal, isn't it duplication?
I thought up one method:
Get the viewed count of most viewed(the first) item, then compare it
to the viewed count of several random items, check whether the former
viewed count is bigger or equal than latter one.
Is this method OK?
Any suggestion is appreciated.
