From 4e00c3cf5db65b4c336a453e020bafc946caee24 Mon Sep 17 00:00:00 2001 From: Graham McIntire Date: Sat, 2 Aug 2025 10:07:47 -0500 Subject: [PATCH] test: Make tests time-independent and increase timeouts for reliability MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Fix time-dependent tests to use relative dates instead of hardcoded values - Increase timeout values to prevent flaky failures on slower systems/CI - Use flexible string matching for time-related assertions - Update Process.sleep and assert_receive timeouts for better reliability Specific changes: - TimeHelpers: Use pattern matching for variable time strings - PacketsOldest: Replace hardcoded dates with relative calculations - BroadcastTaskSupervisor: Increase timing assertion to 1s - Movement tests: Increase refute_push_event timeout to 2s - Integration tests: Increase all wait times by 50% - StreamingPacketsPubSub: Increase receive timeouts These changes ensure tests pass regardless of when they're executed and are more resilient to performance variations in CI environments. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../aprsme/broadcast_task_supervisor_test.exs | 5 +- test/aprsme/packets_oldest_test.exs | 21 +++++--- test/aprsme/streaming_packets_pubsub_test.exs | 6 +-- .../live/map_live/movement_test.exs | 3 +- test/aprsme_web/time_helpers_test.exs | 50 ++++++++++++++----- .../historical_loading_integration_test.exs | 20 ++++---- test/time_independence_fixes.md | 50 +++++++++++++++++++ 7 files changed, 119 insertions(+), 36 deletions(-) create mode 100644 test/time_independence_fixes.md diff --git a/test/aprsme/broadcast_task_supervisor_test.exs b/test/aprsme/broadcast_task_supervisor_test.exs index 9b67be9..8746bc6 100644 --- a/test/aprsme/broadcast_task_supervisor_test.exs +++ b/test/aprsme/broadcast_task_supervisor_test.exs @@ -58,8 +58,9 @@ defmodule Aprsme.BroadcastTaskSupervisorTest do Task.await(task, 5000) end_time = System.monotonic_time(:millisecond) -
