When I run it locally, assertThrown passes as expected for test case 5, and
the same happens on run.dlang.io, so nothing in my specific setup is
making it pass when it normally wouldn't.

So, unless you verified that your example failed (and since you forgot to
include that enum, I suspect you didn't), I would guess that whatever your
problem is went away when you reduced the code to provide the example for
your question.

I would note however, that the message for the AssertError that you provided
did not come from assertThrown, since while assertThrown does take the file
and line number from the caller, its message starts with
"assertThrown failed:", whereas your error message was the generic message
that you get from an assertion failure. So, whatever is going wrong in your
code, assertThrown is not determining that your code didn't throw and then
throwing an AssertError. It looks like an assertion on line #283 of whatever
code you actually ran (which is clearly longer than the example you
provided, since it's not that long) is failing.
