Feature: cache_metadata_size
Scenario: print version (-V flag)
When I run cache_metadata_size with -V
Then it should pass with version
Scenario: print version (--version flag)
When I run cache_metadata_size with --version
Then it should pass with version
Scenario: print help (-h)
When I run cache_metadata_size with -h
Then it should pass
And the output should contain exactly:
"""
Usage: cache_metadata_size [options]
Options:
{-h|--help}
{-V|--version}
{--block-size <sectors>}
{--device-size <sectors>}
{--nr-blocks <natural>}
These all relate to the size of the fast device (eg, SSD), rather
than the whole cached device.
"""
Scenario: print help (--help)

Scenario: No arguments specified causes fail

If you specify --device-size you must also give --block-size.
