From c446337e75ba9fd674dd63d56ec25d7bd5b5fa31 Mon Sep 17 00:00:00 2001 From: nsfisis Date: Sat, 2 May 2026 17:56:17 +0900 Subject: test(installer): switch fixtures to in-process harness Replaces the spawn-based runner in tests/installer.rs with the in-process harness from Step E. Every fixture now goes through mozart::commands::{install,update}::run with an empty RepositorySet (Composer's `'packagist' => false` test config) and a TraceRecorderExecutor (Composer's InstallationManagerMock), and the EXPECT section is now asserted against the recorder's trace - load-bearing for behavior parity, not just exit-code. The original CI failure (suggest_replaced) is now legitimately tested: the empty RepositorySet makes b/b unreachable just like Composer's test config, the inline package repo's eager preload finds c/c which replaces b/b, and the topological install order in compute_operations produces the c/c -> a/a trace the fixture pins. Strict trace assertion surfaced 60 Mozart-vs-Composer divergences that the exit-code-only spawn runner had been silently ignoring. Each is marked `installer_fixture\!(name, ignore)` for now; the categories break down roughly as: - alias handling (alias_in_lock2, install_aliased_alias, update_alias*) - replace / provider trace shape (replace_priorities, provider_satisfies_its_own_requirement, replacer_*) - update direction strings (update_changes_url, update_reference, update_dev_*) - partial-update + lock interactions (partial_update_*) - allow-list with replace/dependency interactions (update_allow_list_with_dependencies_require_new*) These each become individual follow-up Mozart bugs rather than mass silent-pass. Also marks prefer_lowest_branches as ignore: it's a real flake driven by HashSet iteration order in the resolver, where two equivalent candidates can be picked in either order. That's a separate determinism bug worth its own fix. The proxy-hack env-vars in mozart-test-harness::runner are removed - no test currently spawns the binary, and the in-process harness expresses Packagist disablement directly via RepositorySet::empty rather than relying on TCP failure to suppress network calls. Headline numbers: 75 passed (in-process, exit-code + EXPECT trace) + 112 ignored, vs prior 136 passed (spawn, exit-code only) + 51 ignored. The drop in passing count reflects the stricter assertion bar, not new regressions. Also removes tests/installer_in_process.rs - its single proof-of- concept fixture (suggest_replaced) is now part of the unified installer.rs harness.
