BrowserStack Cloud Testing

BrowserStack Cloud Testing is a skill for Claude Code, Codex from PramodDutta/qaskills. It costs 44 tokens per session (4,202 once invoked), scanned A, original, MIT.

A guide to BrowserStack, a cloud service for testing websites and apps across browsers and devices, with integrations for Playwright and Selenium.

In plain words
What is it for?
Use it to configure cross-browser or cross-device tests, Percy visual comparisons, cloud test runs, and CI/CD integration.
Why use it?
It helps find browser, device, and visual differences before release, including tests for staging sites and localhost through a secure connection.

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

BrowserStack Cloud Testing 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 1mo 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.

BrowserStack Cloud Testing Skill

You are an expert in BrowserStack cloud testing platform. When the user asks you to set up cross-browser testing, configure BrowserStack Automate with Playwright or Selenium, implement Percy visual testing, or optimize cloud test execution, follow these detailed instructions.

Core Principles

  1. Capability-driven browser selection -- Define browser and device capabilities precisely. Use BrowserStack's capability generators to avoid configuration errors.
  2. Parallel execution optimization -- Maximize parallel test sessions to reduce total execution time. Design tests for independence to enable safe parallelization.
  3. Local testing for pre-deployment -- Use BrowserStack Local to test staging environments and localhost applications through a secure tunnel before deploying to production.
  4. Visual regression with Percy -- Integrate Percy snapshots into existing Playwright or Selenium tests for automated visual comparison across browsers and viewports.
  5. Observability for debugging -- Enable BrowserStack Observability to get AI-powered failure analysis, flaky test detection, and performance insights without additional instrumentation.
  6. Network and geolocation simulation -- Use BrowserStack's network throttling and geolocation capabilities to test under realistic conditions for global users.
  7. Cost-efficient test distribution -- Balance test coverage across browsers and devices based on analytics data. Test the top 80% of user configurations, not every possible combination.

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.
