From 7fb3cb3f3404d479b97644f46ab7f0265c2c5106 Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Sun, 17 May 2026 14:19:08 +0300 Subject: [PATCH] [AZ-600] Batch 80: refactor sitl_replay_builder to strategy pattern Replace per-scenario fixture builders with a parameterized strategy framework so future Derkachi-based scenarios compose existing pieces instead of duplicating ~200 lines of orchestration per scenario. New e2e/fixtures/sitl_replay_builder/builder.py: - VideoSource ABC + StillImagesSource, Mp4PassthroughSource - TlogSource ABC + SyntheticStationaryTlog, ImuCsvTlog - FdrProjection ABC + RawFdrPassthrough, OutboundMessagesProjection - FixtureBuilderConfig + build_fixtures(cfg) orchestrator - Consolidated MAVLink pack_raw_imu / pack_attitude helpers - Consolidated run_gps_denied_replay + write_observer_fixture build_p01_fixtures.py: 423 -> 107 lines (75% reduction). build_p02_fixtures.py: 292 -> 98 lines (66% reduction). _common.py: deleted (folded into builder.py). Tests reorganized: - test_sitl_replay_builder_builder.py (new, 33 strategy-level tests) - test_sitl_replay_builder.py (slimmed, 6 FT-P-01 integration) - test_sitl_replay_builder_p02.py (slimmed, 7 FT-P-02 integration) README documents the strategy framework + a worked example for adding FT-P-04 in ~30 lines (no new strategy code required). Regression gate: 700 passing (was 686; +14 from finer-grained coverage of new strategy classes and the build_fixtures orchestrator).
