# 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).

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