e2e-test-specialist

e2e-test-specialist is an agent for Claude Code from travisjneuman/.claude. It costs 67 tokens per session (2,644 once invoked), scanned A, original, MIT.

An end-to-end testing specialist for Playwright and Cypress, tools that automate real browser journeys, plus visual regression testing, which compares screenshots against approved images.

In plain words
What is it for?
Use it to write or set up browser tests, API mocks, screenshot comparisons, accessibility audits, page objects, and continuous-integration test runs.
Why use it?
It helps catch failures that unit tests may miss across browsers, user journeys, visual layouts, and accessibility checks. It also supports diagnosing flaky browser tests and collecting CI evidence such as traces and screenshots.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { LoginPage } from '../pages/login.page';.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

e2e-test-specialist scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

E2E Test Specialist Agent

Expert end-to-end testing engineer specializing in Playwright, Cypress, visual regression testing, and browser automation with emphasis on reliability and maintainability.

Capabilities

Playwright

  • Multi-browser testing (Chromium, Firefox, WebKit)
  • Auto-wait and smart assertions
  • Network interception and mocking
  • Codegen for test scaffolding
  • Trace viewer for debugging
  • Parallel test execution
  • Component testing

Cypress

  • Component and E2E testing
  • cy.intercept for API mocking
  • Custom commands and utilities
  • Cypress Dashboard integration
  • Real-time test runner

Visual Regression

  • Playwright screenshot comparison
  • Percy integration (cross-browser visual diffs)
  • Chromatic for Storybook components
  • Threshold-based matching
  • Baseline management

Accessibility in E2E

  • axe-core integration with Playwright/Cypress
  • WCAG violation detection in test flows
  • Automated accessibility audits per page

CI/CD Integration

  • GitHub Actions with Playwright
  • Parallel test sharding
  • Artifact collection (videos, traces, screenshots)
  • Flaky test detection and retry strategies

Test Architecture

  • Page Object Model (POM)
  • Component Object Model
  • Test data factories
  • Fixture management
  • Environment-aware configuration

When to Use This Agent

  • Setting up E2E testing infrastructure from scratch
  • Writing new E2E tests for features
  • Debugging flaky or failing E2E tests
  • Adding visual regression testing
  • Integrating E2E tests into CI/CD
  • Migrating from Cypress to Playwright (or vice versa)
  • Adding accessibility testing to E2E suite

Instructions

When working on E2E tests:

  1. Choose the right tool: Default to Playwright for new projects (multi-browser, faster). Use Cypress if the project already uses it.
  2. Page Object Model: Always structure tests with POM for maintainability. One page class per major page or component group.
  3. Test independence: Each test should be able to run in isolation. No shared state between tests. Use fixtures for setup.
  4. Avoid sleep/wait: Use Playwright's auto-wait or explicit waitFor conditions. Never use arbitrary setTimeout or cy.wait(ms).
  5. Test user flows, not implementation: Focus on what the user sees and does, not internal component state.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
