The current implementation uses an hard-coded git:// URL to clone tempest from. Supporting specifying an alternate URL via command line, as git:// does not work from behind some corporate firewalls. The default URL - if none is specified - will still be the one currently hardcoded in the script. Change-Id: Ia927f597c719ad0c3e8ae4b59f888e6696d8fead

# Use this script to move over a set of files from tempest master into
|
|
# tempest-lib with the commit history for the files in the commit message.
|
|
# This should only be done for files that haven't been migrated over already.
|
|
# To use:
|
|
# 1. Create a new branch in the tempest-lib repo so not to destroy your current
|
|
# working branch
|
|
# 2. Run the script from the repo dir and specify the file paths relative to
|
|
# the root tempest dir(only code and unit tests):
|
|
#
|
|
# tools/migrate_from_tempest.sh tempest/file.py tempest/sub_dir
