What it does

E2E Test is an agent skill from exelearning/exelearning. Write or debug repository Playwright specs, including isolated projects, preview frames and multi-user fixtures.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering End-to-end testing and Browser testing. It works with Playwright. The repository describes itself as: eXeLearning is an AGPL-licensed free/libre tool to create and publish open educational resources. The licence is AGPL-3.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 319b5d2. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- make
- bun
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

E2E Test loads about 1.1k tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 266 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~30
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Key Helpers (`workarea-helpers.ts`)

typescript

import {
    waitForAppReady, openElpFile, saveProject,
    openPreviewPanel, closePreviewPanel, getPreviewFrame,
    navigateToPageByTitle, selectFirstPage,
    addIdevice, editIdevice, saveIdevice, deleteIdevice,
    verifyIdeviceInEditor, verifyInPreview, getIdeviceFromYjs,
    handleCloseWithoutSavingModal, expandIdeviceCategory,
} from '../helpers/workarea-helpers';

Common Workflows

typescript

// Server mode only: create an isolated project (static specs use their local/import helpers)
const response = await page.request.post('/api/project/create-quick', { data: { title: 'Test' } });
const { uuid } = await response.json();
await page.goto(`/workarea?project=${uuid}`);
await waitForAppReady(page);

// Add iDevice and verify
await selectFirstPage(page);
await addIdevice(page, 'text');

// Preview
await openPreviewPanel(page);
const frame = await getPreviewFrame(page);
await frame.locator('article').first().waitFor({ timeout: 10000 });

Multi-User (Collaboration) Tests

Reuse collaboration.fixture and waitForYjsSync from the existing multi-user specs. Each user needs a separate authenticated browser context. Do not hand-roll another login/context helper or rely on shared cookies. Use skipInStaticMode for server-only collaboration, preserving the existing justified skip.

Verify Both UI and Backend State

After testing an authorization rejection, verify the resource still exists server-side:

typescript

// UI says 403
expect(deleteResponse.status()).toBe(403);
// Backend confirms resource is untouched
const projectAfter = await page.request.get(`/api/projects/uuid/${uuid}`);
expect(projectAfter.status()).toBe(200);

Commands

bash

bun x playwright test --project=chromium test/e2e/playwright/specs/my-test.spec.ts   # Single spec
make build-static && bun x playwright test --project=static specs/my-test.spec.ts     # Static build
make test-e2e                                                                          # All E2E
make fix                                                                               # Lint

Gotchas

NEVER waitForTimeout() for async — use deterministic waits (waitForFunction, waitFor, waitForSelector). Acceptable: brief 200-500ms pauses for CSS animations only.
Always use helpers from workarea-helpers.ts — reinventing selectors leads to brittle tests.
One project per test — create via API (/api/project/create-quick) in server mode; reuse static specs' local/import setup in static mode, which has no API server.
Validate UI state AND system state — don't just check what the user sees. Also verify Yjs metadata, API responses, and database state where relevant.
Collaboration tests need collaboration.fixture — and must use skipInStaticMode since static mode has no server.
Library loading must work — tests should NOT accept 404 errors. All MathJax/library resources must resolve correctly.

Debugging Failures

typescript

const debugInfo = await iframe.locator('body').evaluate(body => ({
    elementCount: body.querySelectorAll('.target').length,
    htmlSnippet: body.innerHTML.substring(0, 500),
}));
console.log('Debug:', JSON.stringify(debugInfo, null, 2));

Done When

Test creates its own project (isolation)
Uses helpers from workarea-helpers.ts
No waitForTimeout() for async operations
Validates both UI and backend state
Passes: bun x playwright test --project=chromium <file>
make fix passes clean
