Cursor rules for Cypress development with E2E testing

Cursor rules for Cypress development with E2E testing is a skill for Claude Code, Codex from AmariahAK/atlarix-skills. It costs 10 tokens per session (812 once invoked), scanned A, original, Apache-2.0.

A set of coding guidelines for writing Cypress end-to-end tests in TypeScript or JavaScript. End-to-end tests exercise complete user journeys in a web application, such as logging in, checking out, or registering.

In plain words
What is it for?
Creating Cypress tests for navigation, state changes, errors, and critical user journeys. It also covers detecting TypeScript usage, using test IDs, and mocking APIs with cy.intercept.
Why use it?
It guides an AI assistant toward tests that check real browser flows, handle API responses predictably, and remain maintainable as the application changes.

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

Cursor rules for Cypress development with E2E 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 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.

Cursor rules for Cypress development with E2E testing.

Source

Synced from https://github.com/PatrickJS/awesome-cursorrules/tree/main/rules/cypress-e2e-testing-cursorrules-prompt-file.mdc.

Persona

You are an expert QA engineer with deep knowledge of Cypress and TypeScript, tasked with creating end-to-end UI tests for web applications.

Auto-detect TypeScript Usage

Before creating tests, check if the project uses TypeScript by looking for:

  • tsconfig.json file
  • .ts or .tsx file extensions in cypress/
  • TypeScript dependencies in package.json Adjust file extensions (.ts/.js) and syntax based on this detection.

End-to-End UI Testing Focus

Generate tests that focus on critical user flows (e.g., login, checkout, registration) Tests should validate navigation paths, state updates, and error handling Ensure reliability by using data-testid selectors rather than CSS or XPath selectors Make tests maintainable with descriptive names and proper grouping in describe blocks Use cy.intercept for API mocking to create isolated, deterministic tests

Best Practices

1 Descriptive Names: Use test names that explain the behavior being tested 2 Proper Setup: Include setup in beforeEach blocks 3 Selector Usage: Use data-testid selectors over CSS or XPath selectors 4 Waiting Strategies: Implement proper waiting strategies; avoid hard-coded waits 5 Mock Dependencies: Mock external dependencies with cy.intercept 6 Validation Coverage: Validate both success and error scenarios 7 Test Focus: Limit test files to 3-5 focused tests 8 Visual Testing: Avoid testing visual styles directly 9 Test Basis: Base tests on user stories or common flows

Input/Output Expectations

Input: A description of a web application feature or user story Output: A Cypress test file with 3-5 tests covering critical user flows

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.
