From a1d4aa66bc6b3de041ec6e4eb4fe40383945510b Mon Sep 17 00:00:00 2001 From: Daniel Pyrathon Date: Fri, 30 Nov 2018 09:59:37 -0800 Subject: feat(order_utils.py): schema resolver cache (#1317) * Implemented basic functionality for using cache layer of LocalRefResolver * Use `importlib` instead of `imp`, since it's been deprecated. Legacy `load_module()` reloads modules even if they are already imported, causing tests to fail when run in non-deterministic ordering, so we replace it with `import_module()` --- .../order_utils/test/test_json_schemas.py | 23 ++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 python-packages/order_utils/test/test_json_schemas.py (limited to 'python-packages/order_utils/test/test_json_schemas.py') diff --git a/python-packages/order_utils/test/test_json_schemas.py b/python-packages/order_utils/test/test_json_schemas.py new file mode 100644 index 000000000..51cecbd4f --- /dev/null +++ b/python-packages/order_utils/test/test_json_schemas.py @@ -0,0 +1,23 @@ +"""Tests of zero_ex.json_schemas""" + + +from zero_ex.order_utils import make_empty_order +from zero_ex.json_schemas import _LOCAL_RESOLVER, assert_valid + + +def test_assert_valid_caches_resources(): + """Test that the JSON ref resolver in `assert_valid()` caches resources + + In order to test the cache we much access the private class of + `json_schemas` and reset the LRU cache on `_LocalRefResolver`. + For this to happen, we need to disable errror `W0212` + on _LOCAL_RESOLVER + """ + _LOCAL_RESOLVER._remote_cache.cache_clear() # pylint: disable=W0212 + + assert_valid(make_empty_order(), "/orderSchema") + cache_info = ( + _LOCAL_RESOLVER._remote_cache.cache_info() # pylint: disable=W0212 + ) + assert cache_info.currsize == 4 + assert cache_info.hits == 10 -- cgit v1.2.3
