Summary

  • separate CLI, language-server, StyleX, and package-manager end-to-end suites by the external boundary they exercise
  • move the temporary-workspace harness into shared test support
  • replace the hand-written LSP framing and request correlation with the client side of async-lsp
  • retain explicit capability, configuration, diagnostic, cancellation, and shutdown assertions

Why

The package-manager suite had accumulated tests for unrelated CLI, LSP, and generated StyleX integration behavior. Giving each boundary its own test target makes ownership clearer, while using the same LSP transport library as the server removes protocol plumbing that the tests were not intended to verify.

Verification

  • cargo check -p tests-e2e --tests
  • cargo nextest run -p tests-e2e -j 1 (34 passed)
  • regenerated the relocated CLI snapshots with Insta and verified that only snapshot source metadata changed

Summary

  • Split E2E tests into explicit CLI, LSP, StyleX, and package-manager suites.
  • Moved shared workspace support into a reusable test module.
  • Replaced hand-written LSP framing with async-lsp.
  • Preserved assertions for capabilities, configuration, diagnostics, cancellation, and shutdown.
  • Regenerated relocated CLI snapshots with source metadata changes only.

Confidence 4/5 - Structure is clear; test execution is reported, not reproduced

The repository contains the expected test targets and async-lsp integration. The PR reports 34 passing tests through cargo check -p tests-e2e --tests and cargo nextest run -p tests-e2e -j 1. The confidence is reduced because this review did not reproduce those commands.

Walkthrough

The E2E crate now disables automatic test discovery and declares explicit test targets. The LSP harness now uses async_lsp, Tokio runtime components, typed requests, routed notifications, shared client state, and asynchronous shutdown.

Changes

E2E test harness

Layer / File(s) Summary
Explicit test targets and shared support
tests-e2e/Cargo.toml, tests-e2e/tests/cli.rs, tests-e2e/tests/package_manager.rs, tests-e2e/tests/stylex.rs, tests-e2e/tests/support.rs
Cargo declares four explicit integration-test targets and adds the async LSP dependencies. Test modules resolve the shared support module directly. command_builder is public, and unused support items are allowed.
Async LSP client lifecycle
tests-e2e/tests/lsp.rs
The harness replaces manual JSON-RPC framing with async_lsp, Tokio process handling, a routed MainLoop, shared client state, typed notifications and requests, and asynchronous shutdown. Assertions read configuration counts and registrations from the shared state.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to f9c1c

The LSP test harness now tolerates normal transport closure during shutdown, so the prior false teardown failure risk is no longer present.

- Around line 295-302: Update the LSP teardown sequence around
self.server.shutdown, self.server.exit, and self.server.emit(Stop) to treat
returned teardown errors as best-effort, including Error::ServiceStopped, rather
than panicking with unwrap. Preserve the existing 10-second shutdown timeout and
allow execution to continue to the existing main-loop and child-status checks.
