Subject: tests: extend coverage of syslog tests
X-Git-Tag: v5.3~118
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4355057cc82d927c76acc858d956b451f74f4363;p=strace

tests: extend coverage of syslog tests

The current syslog test covers only those cases where the type parameter
is one of SYSLOG_ACTION_READ, SYSLOG_ACTION_READ_ALL,
SYSLOG_ACTION_READ_CLEAR as per codecov.

Add test case to cover the default case.

* tests/syslog.c (SYSLOG_ACTION_SIZE_BUFFER): New macro.
(main): Check SYSLOG_ACTION_SIZE_BUFFER decoding.
