From c96db0402e438f440a43fc45673901764415da17 Mon Sep 17 00:00:00 2001 From: Cliff Hall Date: Sat, 27 Jun 2026 15:26:03 -0400 Subject: [PATCH] test: raise per-file coverage gate to 90 across all clients (closes #1271) (#1532) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * test(web): audit branch-coverage outliers, raise per-file gate to 70 (#1271) The web per-file coverage gate had drifted red: the recently-landed EMA auth feature (core/auth/ema/*) and ClientSettings components shipped undertested, and the prior 50% branch floor let business-logic branches go untested. CI does not run the coverage gate, so this accumulated. Add tests to bring every failing file above the gate and push branch coverage well past 70 across the board, then raise the per-file branches threshold 50 -> 70 in clients/web/vite.config.ts. - EMA core (emaFlow, resourceContext, jwt, wire): 50-88% -> 86-100% branch - EMA OIDC/transport (idpOidc, tokenEndpoint, transportProvider): -> 97-100% - oauthManager / discovery: 73-83% -> 88-92% - ClientSettingsModal/Form, ConnectionInfoContent: 0-88% -> 96-100% - useClientSettingsDraft / useEmaIdpLoginState hooks: 20% -> 100% - TaskStatusBadge / SortableServerCard outliers: 50% -> 100% Coverable branches reached by mocking useComputedColorScheme (dark theme), dnd-kit useSortable (isDragging), and fetch/OIDC paths. Remaining sub-100 branches are genuinely-unreachable defensive guards or happy-dom-inherent (portal / useMediaQuery / typeof window) and documented in test comments. No source files changed. Global web branch coverage 88.73% -> 90.63%. AGENTS.md updated; cli/tui/launcher stay at 50 (out of scope). Co-Authored-By: Claude Opus 4.8 (1M context) * test: raise per-file coverage gate to 90/90/90/90 across all clients Follows the #1271 web branch-coverage audit (50 -> 70) by raising the whole per-file gate to >=90 on all four dimensions — lines, statements, functions, branches — for web, cli, tui, and launcher (core/ is measured under the web suite). A codebase-wide audit added real tests for every outlier and brought global coverage up across the board. Config: all four vitest/vite coverage configs set to 90/90/90/90. Two pure-type modules (core/mcp/import/types.ts, clients/web/server/ types.ts) added to the web coverage exclude list, matching the existing type-only exclusions. Tests: ~50 test files extended/created across core (auth, ema, mcp, remote, state, storage, react), web components/screens/server, and the cli/tui clients. Highlights: full EMA OAuth flow + transport coverage, inspectorClient/remote server backfill, every Mantine control's handler branches, and the cli unsupported-method / argv-fallback paths. Genuinely-unreachable branches are annotated at the source with justified `/* v8 ignore -- */` comments rather than lowering the gate: happy-dom-inherent paths (Mantine portal, useMediaQuery, typeof window SSR guards), React StrictMode effect replay, and provably-dead defensive guards (?? fallbacks the types make impossible, Select.onChange values outside the allowed list). No runtime logic changed; the only structural edits are two behavior-preserving refactors (ResourceTemplatePanel hoists the field value to a local so the ignore applies in JSX; ToolsScreen swaps a ternary for an if) and prettier line-wrapping. Also fixed a flaky real-timer debounce assertion in PromptArgumentsForm (asserted an exact sibling-typing interleaving that raced the 300ms debounce; now asserts the load-bearing fact — a non-empty fire-time sibling capture). AGENTS.md updated to describe the uniform 90 gate and the v8-ignore policy. All four client coverage gates, root validate, storybook (370), and smoke pass. Co-Authored-By: Claude Opus 4.8 (1M context) * test(web): make connect-crash SSE reader stop on the terminal event `readSseEvents` looped until the server closed the stream (`done`). The server closes the events stream immediately after writing the terminal `transport_error`, but under the heavy parallel scheduler pressure of a full `coverage` run (v8 instrumentation across all workers) that close can lag far enough behind the event to trip the 30s test timeout — a hang, not a wrong result. This made the test intermittently fail under `npm run coverage` (it passed in isolation and under CI's lighter `test:integration`). Stop reading as soon as the terminal `transport_error` event arrives (cancelling the reader) instead of waiting only for `done`. That event is always the last one the session queue emits, so nothing is lost, and the test no longer depends on stream-close timing. The `done` break is kept for any stream that closes first. Verified green across two consecutive full `npm run test:coverage` runs (3094 tests) where it previously hung, plus isolation (~0.5s).

driven by items on the project board. - Run TUI tests with `npm run test` from `clients/tui/` - The repo root has no aggregate `test` script — each client self-validates, so run `npm run validate` from the root (all clients, fast) or `cd clients/ && npm run validate` (one client). Each client still exposes its own `test` / `test:coverage` for quick iteration. - **`validate` is fast: it runs `test`, not `test:coverage`.** The coverage gate (slower — adds v8 instrumentation, and for web the integration project) is a **separate** top-level `npm run coverage` (and per-client `coverage:web` / `coverage:cli` / `coverage:tui` / `coverage:launcher`, each delegating to that client's `test:coverage`). Run `npm run coverage` when you want the gate. **CI does NOT run `coverage`** — the gate is local-only; CI runs `validate` (fast) plus the web integration suite (`clients/web` `test:integration`, no coverage) so the integration paths are still exercised. -- Each client's `test:coverage` enforces a per-file gate: lines ≥ 90, statements ≥ 85, functions ≥ 80, branches ≥ 50 (CI enforces this gate). Branches is intentionally relaxed because Mantine portal/media-query branches are not exercisable under happy-dom; new business-logic branches should still be covered. +- Each client's `test:coverage` enforces a **uniform per-file gate of ≥ 90 on all four dimensions** — lines, statements, functions, and branches — across `clients/web`, `clients/cli`, `clients/tui`, and `clients/launcher` (CI enforces this gate). This is the result of a codebase-wide audit: the branch floor was first lifted 50 → 70 for web (#1271), then the whole gate raised to 90 with real tests added for every outlier. Genuinely-unreachable branches are **not** waved through by lowering the gate — they are annotated at the source with a justified `/* v8 ignore … -- */` comment. Acceptable reasons are happy-dom-inherent paths (Mantine portal mount points, `useMediaQuery` fallbacks, `typeof window` SSR guards), React StrictMode effect-replay blocks, and provably-dead defensive guards (e.g. a `?? fallback` for a value the types guarantee non-null, or a `Select.onChange` receiving a value outside the allowed list). New code must clear 90 on every dimension; reach for a justified `v8 ignore` only when a branch is genuinely impossible to exercise. - The **same per-file gate** is enforced for the CLI and TUI (#1484), not just web: - **CLI** (`clients/cli`): tests run **in-process** by importing `runCli()` (see `__tests__/helpers/cli-runner.ts`) so `clients/cli/src` is measured under v8 instrumentation. A thin out-of-process layer (`__tests__/e2e.test.ts` + `scripts/smoke-cli.mjs`) still spawns the built binary for the shebang/`process.exit` paths; `src/index.ts` (binary bootstrap) is the only coverage exclusion. `commander` uses `.exitOverride()` so a parse error throws instead of tearing down the test worker. - **TUI** (`clients/tui`): the gate covers the **non-React logic** only — `logger.ts`, `components/tabsConfig.ts`, and `utils/*` (server resolution lives in `core/` and is measured by the web suite). The Ink components, `App.tsx`, and `hooks/` are an **interim exclusion** in `clients/tui/vitest.config.ts` pending the renderer-based follow-up (#1501). When adding new **non-React** logic under `clients/tui/src`, it falls under the gate automatically — add tests for it. diff --git a/clients/cli/__tests__/cli.test.ts b/clients/cli/__tests__/cli.test.ts index c833bf48..ca393100 100644 --- a/clients/cli/__tests__/cli.test.ts +++ b/clients/cli/__tests__/cli.test.ts @@ -1,5 +1,9 @@ -import { describe, it, expect } from "vitest"; +import { describe, it, expect, vi } from "vitest"; +import { mkdtempSync } from "node:fs"; +import { tmpdir } from "node:os"; +import { join } from "node:path"; import { runCli } from "./helpers/cli-runner.js"; +import { runCli as runCliDirect } from "../src/cli.js"; import { expectCliSuccess, expectCliFailure, @@ -1018,4 +1022,33 @@ describe("CLI Tests", () => { expectCliFailure(result); }); }); + + describe("argv placeholder fallbacks", () => { + // The cli-runner helper always prepends `["node", "inspector-cli", ...]`, so + // `rawArgs[0]`/`rawArgs[1]` are never undefined through it.
