CTEST_CUSTOM_MAXIMUM_FAILED_TEST_OUTPUT_SIZE

When saving a failing test's output, this is the maximum size, in bytes, that will be collected by the ctest_test() command. Defaults to 307200 (300 KiB).

If a test's output contains the literal string "CTEST_FULL_OUTPUT", the output will not be truncated and may exceed the maximum size.

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

For controlling the output collection of passing tests, see CTEST_CUSTOM_MAXIMUM_PASSED_TEST_OUTPUT_SIZE.
