I wonder whether it would be better to use a kde_ARGS?

like for example

USES=  kde:5,ctest

and do something like

.     if ${kde_ARGS:Mctest}
CMAKE_ARGS+=	-DBUILD_TESTING:BOOL=true
.    else 
CMAKE_ARGS+=	-DBUILD_TESTING:BOOL=false
.   endif

Update after minor clean-up commit.

Minor clean-up changes committed. Reopen for review of testing changes.

As someone who got his system wiped twice (before understanding why) by KDE tests that assume that tests are not run as root (and rm -r /etc should fail, ..., fun stuff), I'm slightly opposed to enable tests by default. That's also why it was explicitly turned off here.

But as far as I can see, you only enable them when explicitly setup in the port to do so, right?
