From 31c675bdeccbd82442591ecd11fe21a17537b03d Mon Sep 17 00:00:00 2001 From: Patrick Selamy Date: Sun, 4 Jan 2026 19:04:32 -0500 Subject: [PATCH] fix: resolve flaky tests in clob_client and websocket (#49) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Changes ### test_get_market_not_found - Updated test to expect `RetryError` instead of `ClobClientError` - The `get_market` method uses the `@with_retry()` decorator, so when the underlying API call fails repeatedly, it raises `RetryError` wrapping the original exception - Removed unused `ClobClientError` import ### test_start_and_receive_trades - Replaced `MagicMock` with a proper `MockWebSocket` class that implements the async iterator protocol correctly - `MagicMock` was passing `self` as an extra argument when calling `__aiter__`, causing "takes 0 positional arguments but 1 was given" - Removed unused `MagicMock` import Closes #49 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- tests/ingestor/test_clob_client.py | 15 ++++++++---- tests/ingestor/test_websocket.py | 39 +++++++++++++++++++++--------- uv.lock | 11 +++++++++ 3 files changed, 48 insertions(+), 17 deletions(-) diff --git a/tests/ingestor/test_clob_client.py b/tests/ingestor/test_clob_client.py index 6c75b18..e507553 100644 --- a/tests/ingestor/test_clob_client.py +++ b/tests/ingestor/test_clob_client.py @@ -7,7 +7,6 @@ import pytest from polymarket_insider_tracker.ingestor.clob_client import ( ClobClient, - ClobClientError, RateLimiter, RetryError, with_retry, @@ -253,17 +252,23 @@ class TestClobClient: assert market.condition_id == "0xabc" assert len(market.tokens) == 2 - @pytest.mark.xfail(reason="Retry logic wraps exception differently - see #49") def test_get_market_not_found(self, mock_base_client: MagicMock) -> None: - """Test error handling when market not found.""" + """Test error handling when market not found. + + When the underlying API call fails, the @with_retry decorator will + retry the operation.
