Feature: Report disk usage
Sometimes you need to check, what amount of disk space a file consumes. We do
NOT support "directories" with `#disk_usage`. This does not work reliably
over different systems. Here can help `'#disk_usage`. But be careful, by
default it uses a block size of "512" (physical block size) to calculate the
usage. You may need to adjust this by using `Aruba.configure { |config|
config.physical_block_size = 4_096 }`. Don't get confused, if you check the
block size by using `File::Stat` (in ruby). It reports the block size of your
filesystem, which can be "4_096" for example.
We're gonna use the (correct) IEC-notation
(https://en.wikipedia.org/wiki/Binary_prefix) here:
\* kilo => kibi
\* mega => mebi
\* giga => gibi
Background:
Given I use a fixture named "cli-app"
Scenario: Show disk usage for file
Given a file named "spec/disk_usage_spec.rb" with:
"""ruby
require 'spec_helper'
RSpec.describe 'disk usage', :type => :aruba do

before(:each) do
write_file file, 'a'
end
let(:size_of_single_block) { File::Stat.new(expand_path(file)).blksize }
it { expect(disk_usage(file)).to eq size_of_single_block }
end
"""
When I run `rspec`
Then the specs should all pass
Scenario: Show disk usage for multiple files
`#disk_usage` creates the sum of all given objects' sizes.
Given a file named "spec/disk_usage_spec.rb" with:
"""ruby
