Recipe: PMDB Client Error Demonstration Standalone Client

“PMDB Client Error Demonstration w/ standalone client” which checks the input options to the pmdb client. This recipe may not use the Holon library in the typical way since the client instances are expected to fail. Instead, the client process should be run directly from Ansible.
In this case, the -u option has had its UUID truncated by one hex character. This should cause the client to exit due to the UUID parsing error. Both the -r and -u option should have recipe sub cases.what

$ echo $?
134
For now it’s ok if the error code is not equal to 134 as long as it’s non-zero.
Usage: ./pumicedb-client-test [-a (use async requests)] -r <UUID> -u <UUID>
- Please verify that the binary fails when either -r and -u are missing.
- Ensure that unspecified options cause the program to fail.
Run the client with correctly formed UUIDs which are not known to the configuration. Here I’ve switched the last two chars of the UUID from 89 -> 90.
