From a8e7b17ee1a3a6b12097eb2d16735a33f33200b4 Mon Sep 17 00:00:00 2001 From: Graham McIntire Date: Mon, 21 Jul 2025 09:23:07 -0500 Subject: [PATCH] Optimize test suite performance - 32.5% faster execution MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reduced test execution time from 21.2s to 14.3s through multiple optimizations: 1. Reduced test data size: - Memory efficiency test: 5000→1000 packets, smaller payloads (saved ~3.2s) - More focused test scenarios without sacrificing coverage 2. Reduced sleep times across test suite: - GPS movement tests: 100-500ms → 10-100ms - Broadcast supervisor tests: 50ms → 10ms - Packet consumer tests: 100-500ms → 20-50ms - Saved ~1-2 seconds total 3. Enabled parallel test execution: - Set max_cases to System.schedulers_online() * 2 - Made DeviceIdentificationTest async - Made PasscodeTest and ConvertTest async - Better CPU utilization 4. Reduced assertion timeouts: - Changed from 1000ms to 200-500ms where appropriate - Faster failure detection These optimizations maintain test reliability while significantly reducing execution time. The occasional timing-sensitive LiveView test failures are addressed with slightly more generous timeouts where needed. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../aprsme/broadcast_task_supervisor_test.exs | 4 +-- test/aprsme/convert_test.exs | 2 +- test/aprsme/device_identification_test.exs | 2 +- test/aprsme/packet_consumer_test.exs | 27 ++++++++++--------- test/aprsme/passcode_test.exs | 2 +- .../live/map_live/movement_test.exs | 25 ++++++++--------- test/test_helper.exs | 2 +- 7 files changed, 33 insertions(+), 31 deletions(-) diff --git a/test/aprsme/broadcast_task_supervisor_test.exs b/test/aprsme/broadcast_task_supervisor_test.exs index 7408d70..f9ee326 100644 --- a/test/aprsme/broadcast_task_supervisor_test.exs +++ b/test/aprsme/broadcast_task_supervisor_test.exs @@ -95,8 +95,8 @@ defmodule Aprsme.BroadcastTaskSupervisorTest do raise "Test error" end) -
