run_tests.bash

#!/bin/bash

# simple script to run tests on dev machine for few python versions (by default 2.7, 3.4)
# This script will automatically create separate virtual environment for each test.
# 
# Following environment variables could be used to configure test run:
#   - TEST_MODULE - python module name to look for test cases in
#                   (default: odoo_rpc_client.tests.all)
#   - PY_VERSIONS - string that contains space separated python versions to test app on



SCRIPT=`readlink -f "$0"`
SCRIPTPATH=`dirname "$SCRIPT"`  # directory that contains this script

    Usage:

        run_tests.bash [options]
    Available options:
        --py-version v1         - use specific python version. may be present multiple times
        --with-db               - perform database related tests (create, dump, drop, restore)
        --recreate-db           - recreate test database at start
        --test-module <module>  - run specific test suit (python module that contains test cases)
        --reuse-venv            - do not delete/recreate virtual environment used for test
        --flake8                - Run flake 8 on project's code
