This module is meant to reduce code size by performing common test procedures.
Generally, code here should look like test code.
More specifically:
- Functions in this module should raise exceptions if things go wrong
(unlike functions in kvm_utils.py and kvm_vm.py which report failure via
their returned values).
- Functions in this module may use logging.info(), in addition to
logging.debug() and logging.error(), to log messages the user may be
interested in (unlike kvm_utils.py and kvm_vm.py which use
logging.debug() for everything that isn't an error).
- Functions in this module typically use functions and classes from
lower-level modules (e.g. kvm_utils.py, kvm_vm.py, kvm_subprocess.py).
- Functions in this module should not be used by lower-level modules.
- Functions in this module should be used in the right context.
For example, a function should not be used where it may display
misleading or inaccurate info or debug messages.
