# The command to see the space used under each directory is `du -sh /*`
# The `2> /dev/null` at the end is to avoid get lost with a lot of minor errors.
# For the example 'mydockerimage' is the name of the Docker image to be checked.
# Another way is to use Dive (https://github.com/wagoodman/dive), a really nice tool for this.

docker run --rm -u root --entrypoint "" mydockerimage du -sh /* 2> /dev/null

Install gem before to require it at Test-Kitchen

Context

I was trying some TDD with [Tesk-Kitchen][1] and [ServerSpec][2] when I found myself in the following case scenario:

I have a integration test like this:

# cookbook_webtest/test/integration/default/serverspec/localhost/webtest_spec.rb

juanje

# To have the last stable version of Chef (10.14.4)

# with the official Vagrant boxes
config.vm.provision :shell,
  :inline => "gem search -i chef -v 10.14.4 || gem install chef -v 10.14.4 --no-rdoc --no-ri"

# with the official Opscode boxes
config.vm.provision :shell,
  :inline => "/opt/chef/embedded/bin/gem search -i chef -v 10.14.4 || /opt/chef/embedded/bin/gem install chef -v 10.14.4 --no-rdoc --no-ri"

This is a short and simple example of custom assertions for Minitest.

They are very basic, but they help me to learn it. And I can use the to test some very simple use case of remote conection without install a bunch of gems.

I learn what I needed for this from this article and the minitest-chef-handler's code.

It can be improved a lot using Nokogiri and other Ruby libraries.
