CTEST_CUSTOM_TEST_OUTPUT_TRUNCATION

Added in version 3.24.

Set the test output truncation mode in case a maximum size is configured via the CTEST_CUSTOM_MAXIMUM_PASSED_TEST_OUTPUT_SIZE or CTEST_CUSTOM_MAXIMUM_FAILED_TEST_OUTPUT_SIZE variables. By default the tail of the output will be truncated. Other possible values are middle and head.

It is initialized by ctest(1), but may be edited in a CTestCustom file. See ctest_read_custom_files() documentation.
