TIMEOUT_AFTER_MATCH¶
Change a test’s timeout duration after a matching line is encountered in its output.
Usage¶
add_test(mytest ...)
set_property(TEST mytest PROPERTY TIMEOUT_AFTER_MATCH "${seconds}" "${regex}")
Description¶
Allow a test seconds to complete after regex is encountered in
its output.
When the test outputs a line that matches regex its start time is
reset to the current time and its timeout duration is changed to
seconds. Prior to this, the timeout duration is determined by the
TIMEOUT property or the CTEST_TEST_TIMEOUT
variable if either of these are set. Because the test’s start time is
reset, its execution time will not include any time that was spent
waiting for the matching output.
TIMEOUT_AFTER_MATCH is useful for avoiding spurious
timeouts when your test must wait for some system resource to become
available before it can execute. Set TIMEOUT to a longer
duration that accounts for resource acquisition and use
TIMEOUT_AFTER_MATCH to control how long the actual test
is allowed to run.
If the required resource can be controlled by CTest you should use
RESOURCE_LOCK instead of TIMEOUT_AFTER_MATCH.
This property should be used when only the test itself can determine
when its required resources are available.
