8 Commits • 1 Features
Jun 1, 2026June 2026 (OpenRailAssociation/osrd): Focused on stabilizing end-to-end tests and enabling faster, more reliable feedback for CI and local development. Delivered a comprehensive set of E2E reliability improvements, infrastructure validation during scenario creation, and robust resource management for API contexts, complemented by targeted fixes to flaky train-scheduling tests and loading-state handling. These changes reduce test flakiness, prevent resource exhaustion, and accelerate iteration cycles, contributing to higher confidence in releases and deployments. Key changes include tuning Playwright actionTimeout for CI vs local runs, ensuring loading spinners disappear before actions, asserting selected infrastructure during scenario creation, reusing a single API request context with sequential exception handling, increasing timeouts for slow E2E tests, fixing train scheduling test identifiers, disposing of API contexts to prevent socket hang-ups, and extracting shared times-stops scenario setup into a fixture.
