If your program returns a 0, it passes. If it does not, it fails.

If you want to invert this logic, set the test property "WILL_FAIL".
If you want to base the pass/fail value on test output, set the test
property "PASS_REGULAR_EXPRESSION" or "FAIL_REGULAR_EXPRESSION" : if the
output matches the regex, it passes or fails accordingly.

i.e.:
set_property(TEST test1 PROPERTY WILL_FAIL TRUE)
would invert the pass/fail logic

see also:
$ cmake --help-property WILL_FAIL
$ cmake --help-property PASS_REGULAR_EXPRESSION
$ cmake --help-property FAIL_REGULAR_EXPRESSION
$ cmake --help-command set_property

Yes, that's correct.

testpage should be the name of a test added using add_test. It can have
*anything you want to test* inside of it....

ctest -R testpage will execute the test as specified in the add_test
command.
