- TIMEOUT_AFTER_MATCH
- -------------------
- Change a test's timeout duration after a matching line is encountered
- in its output.
- Usage
- ^^^^^
- .. code-block:: cmake
- 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
- :prop_test:`TIMEOUT` property or the :variable:`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.
- :prop_test:`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 :prop_test:`TIMEOUT` to a longer
- duration that accounts for resource acquisition and use
- :prop_test:`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
- :prop_test:`RESOURCE_LOCK` instead of :prop_test:`TIMEOUT_AFTER_MATCH`.
- This property should be used when only the test itself can determine
- when its required resources are available.
