Labels: newbie (was: )
> Add support for verifying multiline log entry
> ---------------------------------------------
>
> Key: HDDS-1889
> URL: https://issues.apache.org/jira/browse/HDDS-1889
> Project: Hadoop Distributed Data Store
> Issue Type: Test
> Components: test
> Reporter: Dinesh Chitlangia
> Priority: Major

> This jira aims to test the failure scenario where a multi-line stack trace
> will be added in the audit log. Currently, for test assumes that even in
> failure scenario we don't have multi-line log entry.
> Example:
> {code:java}
> private static final AuditMessage READ_FAIL_MSG =
> new AuditMessage.Builder()
> .setUser("john")
> .atIp("192.168.0.1")
> .forOperation(DummyAction.READ_VOLUME.name())
> .withParams(PARAMS)
> .withResult(FAILURE)
> .withException(null).build();
> {code}
> Therefore in verifyLog() we only compare for first line of the log file with
> the expected message.
> The test would fail if in future someone were to create a scenario with
> multi-line log entry.
> 1. Update READ_FAIL_MSG so that it has multiple lines of Exception stack
> trace.
> This is what multi-line log entry could look like:
> {code:java}
> ERROR | OMAudit | user=dchitlangia | ip=127.0.0.1 | op=GET_ACL

> 2. Update verifyLog method to accept variable number of arguments.
> 3. Update the assertion so that it compares beyond the first line when the
> expected is a multi-line log entry.
