[TYPO3-mvc] viewhelpers: stripHTML & removeXSS - what should be tested?

[Andreas Rieser]

Hi @ all!

This morning I sent Sebastian Kurfürst the last two missing  
ViewHelpers stripHTML & removeXSS - well, not exactly a big deal,  
because these are only wrappers for core / php functions, but better  
than nothing...
Btw.: They are in the wiki as well. Currently I have not created  
tests for these - but I'd like to do this as well. My question is:  
what should be tested?

Is it sufficient to take example strings, pass them to the functions  
and assert that the result is correct?
I mean something really basic like:

stripHTML: "<h1>Test</h1>" ->  "Test"
removeXSS: "<h1>Test<script>alert('XSS vulnerability!)</script></h1>"  
-> "<h1>Test</h1>"

Or should testing go into details - if yes, how far does this make  
sense?

Regards,
Andreas
