Shell Backend¶

Overview¶

bzaf can execute shell commands in order to verify bugs.

Shell is the most basic implementation of a backend which is robust and allows many various robust scenarios to be verified.

Example¶

Basic scenario¶

Execute a single command and expect a return code equal to 0:

bzaf:
  version: 1
  job_env: 'all'
  verification_steps:
    - name: Check existence of command
      backend: shell
      cmd: which openstack
      rc: 0

Negative Testing Scenario¶

Execute a command and expect to fail with a return code of 1:

bzaf:
  version: 1
  job_env: 'all'
  verification_steps:
    - name: Check existence of command
      backend: shell
      cmd: which openstack
      rc: 1

Spec¶

Minimal microversion: 1

Maximum microversion: 1

Attributes¶

cmd¶

Shell command that will be executed.

rc¶

Expected return code of command execution.
