Gemini Prompt for Creating E2E Tests
End-to-end (E2E) tests are essential to ensure the overall functioning of an application, but writing them is often time-consuming and repetitive. Google's AI model Gemini excels in generating structured code and can significantly speed up the creation of comprehensive E2E test suites. By providing the technical context of your application — technology stack, critical user journeys, and the test framework used — Gemini can produce robust test scenarios covering main flows and edge cases. Whether you use Playwright, Cypress, or Selenium, the AI adapts to your framework's conventions to generate directly usable code. The prompt engineering approach allows you to specify the desired coverage level, preferred selector patterns, and test data management strategy. The result: maintainable, readable tests aligned with your team's best practices, produced in a fraction of the usual time.
The prompt
You are a senior QA engineer specialized in end-to-end testing. I am working on a [APPLICATION TYPE: web/mobile/desktop] application built with [TECH STACK: e.g. React, Node.js, PostgreSQL].
E2E test framework used: [FRAMEWORK: Playwright/Cypress/Selenium]
Base URL: [URL]
Here is the user path to test:
[DESCRIBE THE COMPLETE FLOW STEP BY STEP]
Generate a complete E2E test suite following these rules:
- Use resilient selectors (data-testid, ARIA roles) — never fragile CSS selectors
- Each test must be independent and idempotent
- Include test data setup and teardown
- Handle loading states and async waits explicitly
- Cover the happy path, error cases (invalid form, network timeout, 403/404) and edge cases
- Add comments explaining the business logic being tested
- Use the Page Object Model pattern for reusability
- Include meaningful assertions at each key step
Structure your response as follows:
- Required Page Objects with their methods
- Configuration and fixtures file
- Test suite organized by feature
- Helper for test data seeding
