This is a test to verify that update_engine correctly checks
signatures in the metadata hash and the update payload itself. This is
achieved by feeding updates to update_engine where the private key
used to make the signature, intentionally does not match with the
public key used for verification.

To run locally, you must set up the file

  src/third_party/autotest/files/shadow_config.ini

with the following content

  [CROS]
  devserver_dir = <full repo path>/src/platform/dev
  dev_server = http://<hostname>:8080

and then start devserver.py outside the chroot:

  $ src/platform/dev/devserver.py

With this in place, you can now run the test:

  $ test_that --fast -b ${BOARD} <DUT_IP>    \
                autoupdate_CatchBadSignatures
