# Integration tests runner should allow to run tests on several versions of ClickHouse.
# Integration tests should be portable.
# To run integration tests following artfacts should be sufficient:
#   - clickhouse binaries (env CLICKHOUSE_TESTS_SERVER_BIN_PATH or --binary arg)
#   - clickhouse default configs(config.xml, users.xml) from same version as binary (env CLICKHOUSE_TESTS_BASE_CONFIG_DIR or --base-configs-dir arg)
#   - odbc bridge binary (env CLICKHOUSE_TESTS_ODBC_BRIDGE_BIN_PATH or --odbc-bridge-binary arg)
#   - library bridge binary (env CLICKHOUSE_TESTS_LIBRARY_BRIDGE_BIN_PATH or --library-bridge-binary)
#   - tests/integration directory with all test cases and configs (env CLICKHOUSE_TESTS_INTEGRATION_PATH or --cases-dir)
#
# 1) --clickhouse-root is only used to determine other paths on default places
# 2) path of runner script is used to determine paths for trivial case, when we run it from repository
