     20 This is a rollback test for Chrome OS releases. It first updates a machine and
     21 then invokes rollback to boot from its previously booted partition. It tests
     22 rollback using the update_engine_client rather than manipulating the UI.
     23 
     24 Setup for this test is exactly like platform_RebootAfterUpdate. Namely:
     25 
     26 Arg:
     27   job_repo_url: repo url to use to find image to update from -- assumes caller
     28                 has staged image. By default if host[repo_job_url] is set, it'll
     29                 use that. This overrides that value. This value must follow
     30                 the package_url_pattern in the global config.
     31 
     32 To run locally:
     33   1) Setup your devserver in your shadow config that your DUT can reach.
     34   2) Start your devserver and stage the image you want for example:
     35      http://localhost:8080/stage?archive_url=\
     36      gs://chromeos-image-archive/parrot-release/R32-4793.0.0&\
     37      artifacts=full_payload (and leave it on).
     38   3) Run with test_that etc passing
     39      args="job_repo_url=http://<your_hostname>:8080/static/\
     40      parrot-release/R32-4793.0.0/autotest/packages"
     41 
     42 For example:
     43 
     44 test_that -b parrot --args="job_repo_url=http://<your_machine>:8080/static/\
     45 parrot-release/R32-4793.0.0/autotest/packages" --fast \
