   Comment from my/Airlfow side (and maybe  more from @ephraimbuddy and @kaxil and @jedcunnningham  who implemented most of the tests there):
   
   Yes. Definitely. Both values schema and unit tests on rendering are super-helpful to keep our Helm Chart "in-check". 
   
   Re - unit tests, we have currently > 350 tests. One thing that I want to look at shortly is to speed them up a bit (this is the only problem we have now that they are rather slow but I believe it should be possible to speed them up a lot). And knowing that other - friendly :) - projects might want to use it we might prioritise it a bit and share our experience.
   
   We use Pytest for all kinds of tests and we think pytest is a great test harness that can be used in various contexts. We tried other solutions before for the helm rendering (helm-unittests)  but it was extremely unfriendly - declarative way of describing and asserting the tests was very difficult to maintain and very few people were even somewhat fluent in it. 
   
   One thing we get with Pytest for the tests - most of our contributors are Pythonistas, and the way we do the rendering tests, it's very much like any other python tests and it's extremely easy to ask even casual contributors to add tests for any contribution they provide and they are able to do it very quickly without too much learning.
