From #4762: before we consider this issue closed, new mocks must automatically be part of the validation test. IMO that's actually more important than making sure we validate all the existing mocks, though both parts would be useful.

My primary question is about the hard-coded list in mocks_test - seems like we should be able to

• read in the list of all mocks from the filesystem - perhaps if this step is fast enough we can just have karma.conf.js do it before every test run and write the results to a file in tests/jasmine/assets?
• only list a set of mocks or patterns to ignore - and then over time we can reduce that to an empty list.

That is a very good idea we could try in another PR.
At first I did try to adapt our image test for this purpose.
But it was rather complicated to acess the system files from the jasmine test.
