[Maria-developers] No MTR tests for --encrypt-binlog feature?

MariaDB - On 10.1 branch, grep on mysql-test for encrypt.binlog returns ./r/mysqld--help.result:180: --encrypt-binlog Encrypt binary logs (including relay logs) ./r/mysqld--help.result:1179:encrypt-binlog FALSE ./suite/sys_vars/r/sysvars_server_embedded.result:698:VARIABLE_NAME ENCRYPT_BINLOG ./suite/sys_vars/r/sysvars_server_notembedded.result:712:VARIABLE_NAME ENCRYPT_BINLOG Thus it does not look that the feature has actual tests. How do you know it works? Thanks, -- Laurynas
