E2E testing patterns, verification procedures, and CI readiness checklists using Playwright.

What it does

Tsh E2E Testing is an agent skill from TheSoftwareHouse/copilot-collections. E2E testing patterns, verification procedures, and CI readiness checklists using Playwright. Use for writing, debugging, or reviewing end-to-end tests, fixing flaky tests, creating Page Objects, mocking external APIs.

Its SKILL.md is about 520 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 Failing and flaky tests. It works with Playwright. The repository describes itself as: Opinionated AI-enabled workflows for product engineering. The licence is MIT.

When your agent uses it

  • Reviewing end-to-end tests
  • Fixing flaky tests
  • Creating Page Objects
  • Mocking external APIs

Example prompts

  • “/tsh-e2e-testing”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 2fbe51e. 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:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    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

Tsh E2E Testing loads about 521 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 137 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~521

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.

E2E Testing Patterns & Practices

Page Object Pattern

typescript
export class FeaturePage {
  constructor(readonly page: Page) {}
  get submitBtn() {
    return this.page.getByRole('button', { name: 'Submit' });
  }
  async navigate() { await this.page.goto('/feature'); }
}

Test Structure

typescript
test('should [behavior] when [condition]', async ({ page }) => {
  const id = `test-${Date.now()}-${test.info().parallelIndex}`;
  // Arrange → Act → Assert
});

Mocking (external APIs only)

typescript
await page.route('**/api/external/**', route => route.fulfill({ status: 200, body: '{}' }));

Verification Loop

RUN → FAIL? → DEBUG (browser_snapshot) → FIX → REPEAT
RuleLimit
Max per test5 iterations → test.fixme()
Max per suite15 iterations → stop
Flaky detection3 pass/fail mix → investigate
Stability3+ consecutive passes required
App bugMark test.fixme('BUG: desc')
Error Recovery
ErrorAction
TimeoutIncrease once → check selector → check if element renders
Element not foundAlternative locator → check DOM → verify page loaded
NetworkRetry → consider mock → verify backend
FlakyExplicit waits → check race conditions → run 5x
App bugMark test.fixme('BUG: desc') - test is skipped; CI usually still passes unless skipped tests fail the build

CI Readiness Checklist

  • Passes headless: npx playwright test --headed=false
  • Uses process.env.BASE_URL
  • No hardcoded credentials
  • Explicit viewport

Quick Reference

Always: accessible locators, unique test data, 3+ passes, mock external APIs Never: waitForTimeout(), CSS selectors, test interdependencies, hardcoded creds
