# This option can be used to temporarily skip flaky tests (using the `--deselect`
# flag) until they are fixed upstream. For example:
# --deselect=tests/integration/api_container_test.py::AttachContainerTest::test_attach_no_stream
# TODO re-enable test_attach_no_stream after https://github.com/docker/docker-py/issues/2513 is resolved
# TODO re-enable test_run_container_reading_socket_ws. It's reported in https://github.com/docker/docker-py/issues/1478, and we're getting that error in our tests.
# TODO re-enable test_create_with_restart_policy after https://github.com/docker/docker-py/pull/3165 is included in a release
# TODO re-enable test_api_error_parses_json after https://github.com/docker/docker-py/pull/3165 is included in a release
# TODO re-enable test_connect_with_ipv6_address after we updated to a version of docker-py with https://github.com/docker/docker-py/pull/3169
# TODO re-enable test_create_network_ipv6_enabled after we updated to a version of docker-py with https://github.com/docker/docker-py/pull/3169
# TODO re-enable test_create_with_ipv6_address after we updated to a version of docker-py with https://github.com/docker/docker-py/pull/3169
