From 430a8221f9e1c9bbff2eabd4782c418b6d33ffea Mon Sep 17 00:00:00 2001 From: Sam Willis Date: Thu, 6 Nov 2025 20:32:51 +0000 Subject: [PATCH 1/2] Implement end-to-end tests for sync feature Implement end-to-end tests for sync feature Implement end-to-end tests for sync feature chore: revert pnpm-lock.yaml to match query-driven-sync chore: update pnpm-lock.yaml with e2e test pg dependencies bump pnpm/action-setup version fix pnpmlockfile format only run normal tests on test command tidy and fix types fixes ci fix tidy checkpoint cleanup between each test add cleanup between tests all e2e tests pass! cleanup live queries fixes for ci add propper mutations to e2e tests fix ci timouts move the badly named accumulated data tests fix ci flake working query e2e tests fix lint fix assertions Fix race condition between test and logical replication stream Handle isNull and isUndefined in expression helpers Ran prettier. fix ci update docs add suport for not to extractSimpleComparisons and
