FAIL_REGULAR_EXPRESSION

If the test output (stdout or stderr) matches this regular expression the test will fail, regardless of the process exit code. Tests that exceed the timeout specified by TIMEOUT fail regardless of FAIL_REGULAR_EXPRESSION. Any non-zero return code or system-level test failures including segmentation faults, signal abort, or heap errors fail the test even if the regular expression does not match.

If set, if the output matches one of specified regular expressions, the test will fail. Example:

# test would pass, except for FAIL_REGULAR_EXPRESSION
add_test(NAME mytest COMMAND ${CMAKE_COMMAND} -E echo "Failed")

set_property(TEST mytest PROPERTY
  FAIL_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"
)

FAIL_REGULAR_EXPRESSION expects a list of regular expressions.
