Running vagrant-spec

The vagrant-spec project is where Vagrant acceptance tests live. NOTE: You must use a hypervisor that allows for nested virtualization to run these tests. So for the vagrant project, it uses the vagrant vmware plugin as a host. If you want to test this locally, please keep in mind that you will need this hypervisor to properly run the tests.

Requirements

  • vagrant installed (from source, or from packages)
  • vagrant vmware plugin
  • vagrant repo
  • vagrant-spec repo

Relevant environment variables:

Below are some environment variables used for running vagrant-spec. Many of these are required for defining which hosts and guests to run the tests on.

  • VAGRANT_CLOUD_TOKEN
    • Token to use if fetching a private box (like windows). This does not have to be explicitly set if you log into Vagrant cloud with vagrant cloud login.
  • VAGRANT_HOST_BOXES
    • Vagrant box to use as a host for installing VirtualBox and bringing up Vagrant guests to test
  • VAGRANT_GUEST_BOXES
    • Vagrant box to use as a guest to run tests on
  • VAGRANT_CWD
    • Directory location of vagrant-spec Vagrantfile inside of the Vagrant source repo
  • VAGRANT_VAGRANTFILE
    • Vagrantfile to use for running vagrant-spec. Unless changed, this should be set as Vagrantfile.spec.
  • VAGRANT_HOST_MEMORY
    • Set how much memory your host will use (defaults to 2048)
  • VAGRANT_SPEC_ARGS
    • Specific arguments to pass along to the vagrant-spec gem, such as running specific tests instead of the whole suite
    • Example: --component cli

How to run

First, we need to build vagrant-spec and copy the built gem into the Vagrant source repo:

cd vagrant-spec
gem build *.gemspec
cp vagrant-spec-0.0.1.gem /path/to/vagrant/vagrant-spec.gem

Next, make a decision as to which host and guest boxes will be used to run the tests. A list of valid hosts and guests can be found in the Vagrantfile.spec adjacent to this readme.

From the root dir of the vagrant project, run the following command:

VAGRANT_CLOUD_TOKEN=REAL_TOKEN_HERE VAGRANT_HOST_BOXES=hashicorp-vagrant/centos-7.4 VAGRANT_GUEST_BOXES=hashicorp-vagrant/windows-10 VAGRANT_CWD=test/vagrant-spec/ VAGRANT_VAGRANTFILE=Vagrantfile.spec vagrant up --provider vmware_desktop

If you are running windows, you must give your host box more memory than the default. That can be done through the environment variable VAGRANT_HOST_MEMORY

VAGRANT_HOST_MEMORY=10000 VAGRANT_CLOUD_TOKEN=REAL_TOKEN_HERE VAGRANT_HOST_BOXES=hashicorp-vagrant/centos-7.4 VAGRANT_GUEST_BOXES=hashicorp-vagrant/windows-10 VAGRANT_CWD=test/vagrant-spec/ VAGRANT_VAGRANTFILE=Vagrantfile.spec vagrant up --provider vmware_desktop

Note: It is not required that you invoke Vagrant directly in the source repo, so if you wish to run it else where, be sure to properly set the VAGRANT_CWD environment variable to point to the proper test directory inside of the Vagrant source.

How to run specific tests

Sometimes when debugging, it's useful to only run a small subset of tests, instead of waiting for evetything to run. This can be achieved by passing along arugments using the VAGRANT_SPEC_ARGS environment variable:

For example, here is what you could set to only run cli tests

VAGRANT__SPEC_ARGS="--component cli"

Or with the full command....

VAGRANT_SPEC_ARGS="--component cli" VAGRANT_CLOUD_TOKEN=REAL_TOKEN_HERE VAGRANT_HOST_BOXES=hashicorp-vagrant/centos-7.4 VAGRANT_GUEST_BOXES=hashicorp-vagrant/windows-10 VAGRANT_CWD=test/vagrant-spec/ VAGRANT_VAGRANTFILE=Vagrantfile.spec vagrant up --provider vmware_desktop

About Vagrantfile.spec

This Vagrantfile expects the box used to end in a specific "platform", so that it can associate a provision script with the correct plaform. Because some boxes might not end in their platform (like hashicorp-vagrant/ubuntu-16.04 versus hashicorp/bionic64), there is a hash defined called PLATFORM_SCRIPT_MAPPING that will tell vagrant which platform script to provision with rather than relying on the box ending with the name of the platform.
