# This script is intended to check the sanity of tempest plugins against
# tempest master.
# What it does:
# * Retrieve the project lists having tempest plugin if project name is
#   given.
# * For each project in a list, it does:
#   * Create virtualenv and install tempest in it
#   * Clone the Project
#   * Install the Project and also installs dependencies from
#     test-requirements.txt.
#   * Create Tempest workspace
#   * List tempest plugins
#   * List tempest plugins tests
#   * Delete virtualenv and project repo
#
# If one of the step fails, The script will exit with failure.
