test(expo): add the Expo e2e tests and their core, copied from clerk-ios and clerk-android by mikepitre · Pull Request #10236 · clerk/javascript

mikepitre · 2026-10-14T17:56:43Z

Description

This is the second of four pull requests that replace the eleven of stack #10100. It sits on #10235, and #10237 sits on it. It holds the end-to-end tests that #10087 added and the shared core they run on, in their final state after the edits of #10131, #10219, #10221, #10225, #10227, and #10230.

integration/expo-native/ is a Node package that installs its own dependencies with npm ci from its own lockfile, outside the pnpm workspace. Its core is the code that clerk-ios, clerk-android, and this repository share: the CLI's verbs, device leases, the throwaway Clerk application of a session, the stand-in for Clerk's Backend API that the tests call, secret redaction, the evidence of a run, the borrowed-device session, and the support code of the e2e tests. The Expo host that builds the fixture and runs the CLI is in #10237, so this package has no bin/control-clerk-expo yet.

The three commits:

Commit	Lines	What it adds
1. The package and its CI job	1,898	`package.json`, the generated `package-lock.json` (1,783 lines), `tsconfig.json`, the `Expo Native Runner Tests` job in `ci.yml`, and the entries that keep the repository's formatter and linter off the package.
2. The shared core	21,995	Copies, except three small files. Check it by hash.
3. The e2e tests	459	17 tests in 12 files under `specs/features/`, in seven feature groups, and `specs/native.ts`, the locators of the fixture's home. Read these.

Of the 109 files of commit 2, 106 files, 21,303 lines, are byte copies of the same path under e2e-tests/ on main of clerk/clerk-ios (bd2266d3c) or clerk/clerk-android (ca990b48), where they were reviewed and merged. src/core/MANIFEST lists the shared files with their hashes, and npm test fails when one drifts. To check them against clerk-ios:

$ git clone -q https://github.com/clerk/clerk-ios /tmp/clerk-ios && git -C /tmp/clerk-ios checkout -q bd2266d3c
$ for d in src/core specs/support testing; do diff -r /tmp/clerk-ios/e2e-tests/$d integration/expo-native/$d; done

The second command prints nothing. src/platform/android/ and test/android.test.ts are copies from clerk-android. The three files of commit 2 that are this repository's own are specs/app.ts, which names the test app and how to launch its dev client, src/platform/ios/simulator.ts, which holds the simctl commands with this repository's log predicate, and test/session-agent.test.ts, the shared test without its one case that names the app sources of clerk-ios.

What to read, in this order:

The e2e tests in specs/features/. Each starts at the fixture's home from test(expo): drive the expo-native fixture from verify launch inputs #10235 and taps to the screen it needs, as a user would. They assert on what a user sees, in the prebuilt views first and on the home for the outcome of a flow. They type only +clerk_test addresses and the test code 424242. Two are for iOS only, so Android runs 15.
package.json: e2e 0.18.0, @e2e-dev/mobile 0.10.0, @e2e-dev/github 0.4.0, ai 7.0.128, and typescript 7.0.2, on Node 24.8 or newer.
The Expo Native Runner Tests job in ci.yml. It runs the package's unit tests and tsc on Linux, with no device and no secret, when a pull request changes the package, the fixture, or an Expo package.

The three changesets are the empty ones that #10087, #10225, and #10227 carried. No published package changes.

npm test in integration/expo-native/ passes 712 of 712 on this branch, and npm run typecheck is clean.

commit: 8b7f1b8

The job skipped its steps on a pull request that changed none of a list of paths, but the list watched the whole Expo packages and missed files the tests read. It now watches the package, the workflows and template screens its tests read, and watches the paths the host tests only require to exist for a deletion or a move alone. A new test runs the job's check against real merge commits, and fails when a test reads a workflow or repository file the list does not watch. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

… inputs

CodeQL flagged the modulo and addition on random bytes in the password generator as biased. A new password now takes each word with randomInt. The run password stays a pure function of the run id, read from its SHA-256 digest. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…tap keeps the next one from counting Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A worktree keeps one application across many runs, and a run finds its users there by the 4-hex tag alone. A new run id now skips the tag of every run the worktree kept. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A four-hex tail had no digit about one time in 50, so the run-groups test that expects one failed at random. The tail is now four decimal digits, for the run password and for seeded users. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…f its wait A Node timer can fire a millisecond before Date.now() shows the full delay. The session agent answers with Date.now() minus the spawn time after a 100 ms timer, so the answer is sometimes 99 and the test failed on its exact lower bound. The bound is now 50 ms. It still fails if the agent answers a recorder that has not run, and no longer depends on millisecond timer precision. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

… space newRun() now creates a per-tag marker with an exclusive write, so two runs that read the same listing cannot both keep one tag. newRunId throws when every tag is taken instead of looping forever. Tests pin that newRun passes the kept runs into the draw, that a claimed tag is skipped, and the exhausted case. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A claim file whose run directory is gone still keeps its tag out of the draw, and the exhausted-space check counts it. newRunId takes the tags directly, so the workspace passes both run directories and claims. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A stray file such as .tag-notes no longer counts toward the tags a worktree has used, so it cannot push the set past the exhausted-space check. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The test passed even if claimTag never wrote the claim file, because the first run's directory already put its tag in the kept list. It now checks the .tag-beef file exists after newRun() and that the tag is not handed out again once the run directory is gone. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
