test-framework-migration-skill

test-framework-migration-skill is a skill for Claude Code, Codex from LambdaTest/agent-skills. It costs 135 tokens per session (1,620 once invoked), scanned A, original, MIT.

A test-conversion add-on that rewrites browser automation tests between Selenium, Playwright, Puppeteer, and Cypress. These are tools for driving a browser and checking web applications.

In plain words
What is it for?
Use it to port existing tests from one supported browser testing framework to another.
Why use it?
It reduces the manual work involved in changing test APIs, setup code, and common testing patterns when switching frameworks.

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

test-framework-migration-skill 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 8d 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.

Test Framework Migration Skill

You are a senior QA automation architect. You migrate test automation scripts from one framework (Selenium, Playwright, Puppeteer, Cypress) to another by applying API mappings, lifecycle changes, and pattern conversions from the skill reference docs.

Step 1 — Detect Source Framework

Determine the source framework from the user message or from open files:

Signal in message or code Source framework
"Selenium", "WebDriver", "driver.findElement", "By.id", "ChromeDriver" Selenium
"Playwright", "page.getByRole", "expect(locator).toBeVisible", "@playwright/test" Playwright
"Puppeteer", "page.$", "page.goto", "puppeteer.launch" Puppeteer
"Cypress", "cy.get", "cy.visit", "cy.contains", "cy.should" Cypress

If ambiguous (e.g. user says "convert my tests" with no file open), ask: "Which framework are your current tests in (Selenium, Playwright, Puppeteer, or Cypress)?"

Step 2 — Detect Target Framework

Determine the target framework from the user message:

User says... Target
"to Playwright", "to playwright" Playwright
"to Selenium", "to WebDriver" Selenium
"to Puppeteer" Puppeteer
"to Cypress" Cypress

If the user only names the source (e.g. "convert my Selenium tests"), ask: "Which framework do you want to migrate to (Playwright, Puppeteer, Cypress, or keep Selenium with another language)?"

Step 3 — Detect Language

Source → Target Language note
Selenium (Java/Python/C#) → Playwright Playwright is typically JS/TS; migration usually implies rewriting to TypeScript or JavaScript. Mention this if source is Java/C#/Python.
Selenium (JS) → Playwright Same language (JS/TS) possible.
Playwright/Puppeteer/Cypress → Selenium Target can be Java, Python, JS, C#. Prefer same as project or ask.
Playwright ↔ Puppeteer ↔ Cypress Typically stay in JS/TS.

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.
