From b29995ba9ec1519a2fb79bdb9ddfa2c134017079 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Cristian=20Pallar=C3=A9s?= Date: Mon, 3 Aug 2026 14:09:29 +0200 Subject: [PATCH 01/13] Add TypeScript e2e test suite driving the built lstk binary 174 tests across 22 files, covering ~130 of the Go integration suite's cases at the behaviour level: assertions describe what a user observes from the CLI, never internal mechanism (telemetry events, token storage, container introspection). Exact output is asserted with toPrintExactly rather than inline snapshots, so expectations are authored rather than recorded and compose with test.each. Runs on Node 26 + pnpm as type-erasable TypeScript, typechecked by TypeScript 7. Terminal tests are mandatory rather than best-effort: node-pty is a required dependency pinned to a prerelease that ships prebuilds for every platform CI runs on, and a missing binding fails the run instead of silently skipping every PTY test. LSTK_E2E_REQUIRE_ALL turns a missing prerequisite into a failure on the CI leg that has all of them. Deliberately not a release gate yet: the test-e2e job stays outside the release job's needs while the suite is evaluated against test/integration.

Never throws on non-zero exit. | +| `home.ts` | `tempHome()` → an isolated HOME with its own config dir, cache dir and file keyring; `home.configPath()` asks the binary itself; `writeConfig` / `readConfig` / `configExists`. Cleans up after the test. | +| `pty.ts` | `lstkPty(args, { home })` → `waitFor` / `expectNever` / `press("enter")` / `exitCode()`, with ANSI stripped so assertions match what a human sees. | +| `docker.ts` | `dockerIsAvailable()`, `docker.pull/tag/inspectContainer/containerIsRunning`, and `useExclusiveEmulator()` for describe blocks that start a container. | +| `license.ts` | `mockLicenseServer("grants" \| "rejects" \| { body })` — a stand-in license API, closed automatically. | +| `platform.ts` | `mockPlatform()` — the full browser login flow, so a test can reach a logged-in state via `lstk login`; `fakeBrowser()` shims `open`/`xdg-open` on PATH and records the URL. | +| `envelope.ts` | `parseEnvelope(stdout)` for the `--json` contract. | +| `matchers.ts` | `toSucceed()`, `toFail()`, `toExitWith(n)`, `toPrint(text \| regex)`; failures print the invocation plus both streams. | + +Two deliberate choices worth knowing: + +- **Docker is driven through the `docker` CLI**, not an API client — it resolves + `DOCKER_HOST`, contexts and non-Docker runtimes exactly as a user's shell does, and + keeps the suite free of native dependencies. +- **Every isolated home gets `DOCKER_HOST` set** to the harness's active context + endpoint. Most runtimes keep their socket under the real home + (`~/.docker/run/docker.sock`, `~/.colima/default/docker.sock`), which the binary can + no longer find once `HOME` is a temp dir. It is a no-op on CI, where + `/var/run/docker.sock` is already correct. + +## Terminal tests + +Roughly half the suite drives lstk on a PTY, so the binding +(`@homebridge/node-pty-prebuilt-multiarch`) is a **required** dependency, imported +statically in [pty.ts](support/pty.ts) and checked once in +[global-setup.ts](support/global-setup.ts). It was an `optionalDependency` at first; +that was a mistake — npm blocked its build script, the binding never loaded, every +terminal test skipped, and the run stayed green. + +It is a native module, but it does not build from source here: `node-pty` carries +Node-API prebuilds for macOS, Windows and Linux (x64 and arm64) inside its npm tarball, +so nothing is fetched or compiled at install and a Node major bump does not strand it. +Its install script still has to be allowed in +[pnpm-workspace.yaml](pnpm-workspace.yaml), or no binary is staged at all. When the +binding cannot load, the run fails with the likely causes spelled out instead of +skipping. + +### The version is pinned exactly, on purpose + +`node-pty@1.2.0-beta.14`, not `^1.1.0`. Two reasons, both measured: + +- **1.1.0 (current stable) is broken on macOS.** Its tarball ships + `prebuilds/darwin-*/spawn-helper` with mode `0644`, and neither its `install` nor its + `postinstall` script fixes that, so every spawn dies with `posix_spawnp failed`. Not a + pnpm artifact — plain `npm install` reproduces it. `chmod +x` on the helper is enough + to fix it, which is what the beta does at pack time (`0755`). +- **1.1.0 ships no Linux prebuilds**, so Linux always runs node-gyp — fine on a CI + runner with python3 and a compiler, fatal on `node:26-slim` or `node:26-alpine`. The + beta adds `linux-x64` and `linux-arm64`. + +Loosening the pin therefore needs a check, not a hope: install it and actually spawn a +PTY on macOS and on a toolchain-free Linux image. Alpine/musl is the one gap — the beta's +Linux prebuilds are glibc-only, so a musl image would have to compile (verified: +`node:26-alpine` fails to load the prebuilt `pty.node`). Nothing in CI runs on musl. + +### Windows + +node-pty drives ConPTY, so terminal tests are not gated to Unix — unlike the Go suite, +where `creack/pty` has no Windows support and every TUI test skips. Whether Bubble Tea +renders identically over ConPTY is unproven; the Windows CI leg is what answers it, and +[tui-runtime-error.pty.test.ts](tests/tui-runtime-error.pty.test.ts) is the probe (no +Docker, no browser, so it runs everywhere). `stripAnsi` carries its own tests because +ConPTY emits more escape sequences than a Unix PTY and a missed one would silently make +`waitFor` blind. + +What still cannot run on Windows is the **browser login flow**: `pkg/browser` invokes +`rundll32 url.dll,FileProtocolHandler` there instead of a shimmable `open`/`xdg-open` +script (`browserCanBeFaked`). Since login is the only way to reach a logged-in state +without touching the store, real-keyring coverage on Windows stays out of reach until +either the browser opener or the keyring identity is overridable. + +## Assert behaviour, not mechanism + +Tests here describe what a user can observe from the CLI. Anything the CLI does not +expose — where a credential is stored, which internal type handled a call — is out of +scope, because encoding it makes the test a second copy of the implementation. + +Three rules follow from that: + +1. **Assert through the CLI where the CLI can answer.** "The emulator started" is + `lstk status` reporting `is running` with an endpoint, not a container of a + particular name existing in Docker. +2. **A user-facing artifact is fair game; internal storage is not.** The config file + counts — it is documented, users edit it, `lstk config path` prints it, and + `--type` is *defined* as rewriting it. The keyring does not. +3. **When the CLI's own message is the only observable, say so in the test.** One test + does this ([start-local-image](tests/start-local-image.test.ts)) and the comment + there explains why; treat it as the exception, not a licence. + +Harness self-tests (tests of this suite's own helpers, not of lstk) live under +[tests/harness/](tests/harness) so they are never mistaken for product behaviour. + +## Exact output: `toPrintExactly`, never a snapshot + +lstk's output is a contract we control, so assert it whole and assert it deliberately: + +```ts +expect(run).toExitWith(1); +expect(run.stdout).toPrintExactly(` + Error: LocalStack AWS Emulator is not running + ==> Start LocalStack: lstk + ==> See help: lstk -h +`); +``` + +`toPrintExactly` (in [support/matchers.ts](support/matchers.ts)) dedents the expected +block — leading/trailing blank lines dropped, common indentation stripped — so it can sit +at the indentation of the surrounding code while still matching byte for byte. Nesting +*within* the block survives, which is what makes those `==>` lines assertable. + +**Inline snapshots are not used here**, deliberately: + +- A snapshot is *recorded*; a literal is *authored*. Only one of them reads as a promise + about what users see, and only one cannot be rewritten by a stray `vitest -u`. +- `toMatchInlineSnapshot` throws inside `test.each` ("InlineSnapshot cannot be used + inside of test.each"). That cost this suite a 4× file expansion before the matcher + existed — 14 cases as 14 near-identical tests instead of two tables. + +The rest of the rules stand whatever the mechanism: + +- **Exact assertions are for output only.** Structured data — argv, environment, parsed + JSON envelopes — gets `toEqual` / `toMatchObject`. +- **Only assert output that is identical on every machine and every run.** Reject a temp + path, port, duration, container ID, version, or — the subtle one — text that adapts to + the host, such as the Docker-unreachable message, whose suggested start commands depend + on which runtimes are installed. Fall back to `toPrint` and say why in a comment, as + [aws-proxy.test.ts](tests/aws-proxy.test.ts) does. +- **Mask only what is incidental.** `normalizeCliOutput()` in + [support/cli-output.ts](support/cli-output.ts) masks a test's temp home. If the value + itself is the point — a resolved config path, a specific port — assert it instead. +- **Keep the promise legible.** Exact text says what the output is, not why it matters. + Where the intent is load-bearing — an error must offer a way forward — say so in a + comment. + +Prefer an exact assertion to an absence check: `not.toPrint("lstk setup aws")` became +`toPrintExactly("")`, which also catches any *other* unwanted output. + +Credentials are the worked example. Nothing reads or writes token storage; the +journey in [login-journey.pty.test.ts](tests/login-journey.pty.test.ts) is: + +1. `start` before logging in → fails, "authentication required" +2. `lstk login` → "Login successful" +3. `lstk login` again → "You're already logged in", browser flow not restarted +4. `start` with **no** token in the environment → gets past auth on its own +5. `logout` → "Logged out successfully", and `start` fails again as in (1) + +That is strictly stronger than reading the keyring: it shows the credential is +*usable*, not merely present, and it holds for whichever backend the binary picked. + +`tempHome()` defaults to `LSTK_KEYRING=file` so a test never touches machine-wide +state. `tempHome({ keyring: "system" })` runs the same journey against the real OS +keyring — the one run that would notice a broken platform adapter — and is skipped +unless `LSTK_E2E_REAL_KEYRING=1` or `CI=true`, since service and account are hardcoded +in `internal/auth/token_storage.go`: one slot per machine, which the journey +overwrites and then deletes. + +## Parallelism + +Test files run in parallel workers. Tests that start an emulator call +`useExclusiveEmulator()`, which takes a machine-wide lock and clears leftover +containers before and after — lstk discovers a running emulator by (image, internal +port), so two of them at once would see each other. Same constraint the Go suite +handles by not marking those tests parallel. + +## CI + +The `test-e2e` job in `.github/workflows/ci.yml` runs on ubuntu / macOS / windows, +writes JUnit XML (`CREATE_JUNIT_REPORT=1`), uploads it, and renders it through +`dorny/test-reporter` — same reporting as the Go suite. It is intentionally **not** in +the release job's `needs:` while the prototype is being evaluated. + +Vitest shards natively if the suite grows enough to need it: set `SHARD_INDEX` / +`SHARD_TOTAL` (`scripts/test-e2e.sh` forwards them to `--shard`). + +## Known costs + +- **Second toolchain.** Node >= 26, pnpm and a lockfile in a Go repo; contributors + need both, and CI grows a Node setup step per leg. +- **The PTY binding is a required native module** pinned to an exact prerelease. Prebuilt + for every platform CI runs on, with no compile and no install-time download — but + bumping it needs a real check, not a version bump. See "Terminal tests". +- **Install-script approvals are a maintenance step.** Adding a dependency that needs + one means updating `pnpm-workspace.yaml`, or the install fails closed. +- **No keyring library.** Reading the store directly from Node is possible but needs + per-platform glue that mirrors `go-keyring` exactly (macOS: `security` plus a + `go-keyring-base64:` value prefix; Windows: no read-capable CLI, so PowerShell + P/Invoke on `CredReadW` with TargetName `:`; Linux: `secret-tool` + with `{service, username}` attributes and a live Secret Service). Off-the-shelf + bindings do not interoperate — `@napi-rs/keyring` wraps keyring-rs, whose Windows + target naming differs, and keytar is archived. The CLI-driven approach above avoids + all of it. diff --git a/test/e2e/package.json b/test/e2e/package.json new file mode 100644 index 00000000..e3cc4cc9 --- /dev/null +++ b/test/e2e/package.json @@ -0,0 +1,22 @@ +{ + "name": "@localstack/lstk-e2e", + "private": true, + "type": "module", + "description": "End-to-end tests that drive the built lstk binary.

Three changes, in order of effect: docker pull costs ~1.8s even when the image is already present, because it still round-trips the registry for the digest. It ran on nearly every container test. Now a local `docker image inspect` (~15ms) answers the same question, memoized per worker. The stand-in container ran `sleep infinity`, which ignores SIGTERM, so every `lstk stop` test waited out Docker's full 10s grace period before the SIGKILL. Trapping TERM takes those tests from 12s to 1.3s. Most container tests no longer need the machine-wide lock: ContainerConfig.Name() returns the canonical `localstack-` only for tag "latest", so a per-test tag yields a per-test container name that lstk's name-first discovery resolves. privateEmulator() mints that identity. Tests that still need the lock keep it, each with the reason recorded inline: zero-config tests (no config means tag "latest" means the canonical name), and anything standing up a container from a real `localstack/*` image reference. The latter is not obvious — discovery falls back to matching any known localstack image exposing 4566, and ContainerPort() is hardcoded to 4566 regardless of the configured port, so such a container is visible to every other test's "is an emulator running" check no matter what it is named. Getting that wrong made the suite fail roughly 2 runs in 9; the fixed suite ran clean 8 times consecutively.

Teardown no longer decides a verdict: a test that starts a real emulator gets a volume directory LocalStack populates as root inside the container, so removing the temp home as the runner user failed with EACCES on cache/certs after the assertions had already passed. Those files need root to delete, which a throwaway container has; failing that, the leftovers stay in the OS temp dir. The completion driver calls the completion function directly rather than pressing Tab, so bash warns that compopt is "not currently executing completion function". macOS bash 3.2 has no compopt builtin at all, which is why it never appeared locally. That one line is filtered; the rest of stderr stays asserted. `start` checks the container runtime before auth, so on a runner without one it reports "Docker is not available" and says nothing about credentials — useless as the auth probe the login journey used it for. Skipped where it cannot be meaningful instead of loosened everywhere. Fake tools are now Node scripts with a .cmd shim on Windows, where a `#!/bin/sh` file with no extension cannot execute at all — 16 proxy tests reported "not found in PATH". Path comparisons go through realpath, since Windows may report an 8.3 short path where Node reports the long one, and the config migration message is asserted with separators normalized.
