Running the test suites

ManageIQ specs are split into several components:

  • vmdb
  • automation
  • migrations
  • providers
  • replication
  • javascript
  • brakeman

Each suite has a pair of Rake tasks to setup and run them, in the form of test:<type> and test:<type>:setup (if required):

rake test:vmdb:setup             # Setup environment for vmdb specs
rake test:vmdb                   # Run all specs except migrations, replication, and automation
rake test:automation:setup       # Setup environment for automation specs
rake test:automation             # Run all automation specs
rake test:migrations:setup       # Setup environment for migration specs
rake test:migrations             # Run all migration specs
rake test:providers:amazon:setup # Setup environment for Amazon provider specs
rake test:providers:amazon       # Run all Amazon provider specs
rake test:replication:setup      # Setup environment for replication specs
rake test:replication            # Run all replication specs
rake test:javascript:setup       # Setup environment for javascript specs
rake test:javascript             # Run all javascript specs
rake test:brakeman               # Run Brakeman

Running the vmdb suite in parallel

The main vmdb suite of tests can be run in parallel, utilizing multiple processor cores. These separate processes run concurrently and are then collected and reported on together when they all complete their delegated work. You can run the entire vmdb suite or select spec files within it.


Running tests in parallel requires as many different databases as cores you plan to run on.

To set up these databases, simply execute the following command:

$ PARALLEL=true bin/rake test:vmdb:setup

Run the entire suite in parallel

You can run the entire suite in parallel using the following command:

$ PARALLEL=true bin/rake test:vmdb

Passing RSpec options to the rake tasks

RSpec accepts a SPEC_OPTS environment variable to pass command line flags. This is necessary when you wish to use some command line option with our built-in rake commands to run the tests.

For example, I may wish to set a particular seed and stop running the tests immediately on a failure:

$ PARALLEL=true SPEC_OPTS="--seed 1234 --fail-fast" bin/rake test:vmdb:setup

Note that --fail-fast will stop whichever core encountered the error, not every core at the first error found.

Running specific spec files in parallel

You needn’t run the entire vmdb suite to take advantage of running tests in parallel. Use parallel_rspec to run specific directories of spec files.

For example, I may have done some work on the front end and want to run the controller, helper, and view specs specifically:

$ parallel_rspec spec/controllers spec/helpers spec/views

This will run all of the specs in their respective directories, in parallel. Note you do not need PARALLEL=true using parallel_rspec.

Other tips:

  • You can get creative with searching and globbing patterns to feed to the parallel_rspec command. For example, I might have recently made some pretty drastic changes to role checking code having to do with a method named #role_allows. To quickly run specs that might touch this code, I can pass in all tests that mention it directly:

    $ parallel_rspec `git grep -l role_allows spec`
  • Each core requires a certain amount of overhead involved with loading all of the application code, etc. Always running the maximum number of cores available isn’t always beneficial to fast tests. If you’re running a subset of tests and parallel_tests reports that you’re running a very small number of specs across each core, try using fewer cores doing more work instead. You can specify the number with the -n option. For example, to run all the request specs with four cores:

    $ parallel_rspec -n 4 spec/requests
  • We use the parallel_tests gem to make all of this possible - Go check out the documentation to learn even more things you can do with running ManageIQ tests in parallel!

Running JS specs

The rake task (rake spec:javascript in ui-classic) runs all the JS specs in spec/javascripts/**/*_spec.js in a headless browser.

For debugging, rake environment jasmine runs a webserver listening on localhost:8888.
