class EL_CRC_32_TESTABLE

(source code)

Client examples: COMMA_SEPARATED_IMPORT_TEST_SET

description

Routines for use with EL_EQA_TEST_SET to do regression testing based on CRC-32 checksum of logged/console output. See **do_test* routine.

notes

The type of log must be set to EL_CRC_32_CONSOLE_ONLY_LOG by running the test from a sub-application conforming to EL_CRC_32_AUTOTEST_APPLICATION
