Not sure what you mean by beforehand.  Don't you run all your unit tests
before putting each revision of your code into production?  So run those
tests twice, once on 2.7, and once on 2.4.  A unit test that's testing
code with a ternary operator will fail, without any need for a separate
test.

if it doesn't, then you've got some coverage gaps in your unit tests.
