Convenience script to execute tests/ and helper bin/ scripts.
|
|
|
|
|
|
|
|
USAGE: $0 script_path [arguments]
|
|
|
|
script_path: path to python script to execute, relative to driver root folder
|
|
|
|
arguments ...: arguments passed to program in sys.argv
|
|
|
|
|
|
|
|
ENVIRONMENT:
|
|
|
|
XDS_K8S_CONFIG: file path to the config flagfile, relative to
|
|
|
|
driver root folder. Default: config/local-dev.cfg
|
|
|
|
Will be appended as --flagfile="config_absolute_path" argument
|
|
|
|
XDS_K8S_DRIVER_VENV_DIR: the path to python virtual environment directory
|
|
|
|
Default: $XDS_K8S_DRIVER_DIR/venv
|
|
|
|
DESCRIPTION:
|
|
|
|
This tool performs the following:
|
|
|
|
1) Ensures python virtual env installed and activated
|
|
|
|
2) Exports test driver root in PYTHONPATH
|
|
|
|
3) Automatically appends --flagfile="\$XDS_K8S_CONFIG" argument
|
|
|
|
|
|
|
|
EXAMPLES:
|
|
|
|
$0 bin/run_td_setup.py --help # list script-specific options
|
|
|
|
$0 bin/run_td_setup.py --helpfull # list all available options
|
