Cypress Component Testing: Test React, Vue, and Angular Components

Cypress Component Testing lets you mount individual components in a real browser and test them in isolation — without starting your full application. This approach fills the gap between unit tests (jsdom, fast but imprecise) and E2E tests (full browser, accurate but slow and expensive to maintain). This guide covers setup

Cypress CI/CD Integration: GitHub Actions, Parallelization, and Reporting

Getting Cypress tests to run reliably in CI is more than installing a package. Browser tests need headless browsers, system dependencies, shared state management, and enough parallelism to keep pipelines fast. This guide covers the complete setup: GitHub Actions workflow, browser installation, parallelization, artifacts, and reporting. Basic GitHub Actions Setup

Cypress Best Practices: Custom Commands, Page Objects, and Anti-Patterns

A Cypress test suite that starts clean can become a maintenance nightmare if it grows without structure. Duplicated login flows, fragile selectors, and tests that share state all contribute to slow, flaky, hard-to-debug pipelines. This guide covers the patterns that keep Cypress test suites maintainable as they grow. Use data-cy

Playwright Component Testing: Test React and Vue in Isolation

End-to-end tests are great for validating full user flows, but they're slow to write and slow to run when you're testing a single component. Playwright Component Testing lets you mount individual React, Vue, or Svelte components in a real browser — without standing up your full app

Playwright API Testing: Test REST Endpoints Without a Browser

Playwright is famous for browser automation, but it ships with a capable HTTP client that lets you test REST APIs directly — no browser required. This makes it a powerful all-in-one tool: write your UI tests and API tests in the same framework, share authentication, and chain API calls with browser

Playwright in CI/CD: GitHub Actions, Docker, and Parallel Sharding

Getting Playwright tests to run reliably in CI is one of the most common challenges teams face. Tests that pass locally fail in CI, pipelines are slow, and flaky results erode trust in the suite. This guide covers everything you need: GitHub Actions setup, Docker configuration, parallel sharding, retries, and

End-to-End Testing Guide: What It Is, Tools, and Best Practices (2026)

Your unit tests pass. Your integration tests pass. And yet users keep reporting broken checkouts, failed logins, and data that doesn't save. End-to-end testing is the safety net that catches what all your other tests miss — because it actually simulates what a real user does. Key Takeaways End-to-end

End-to-End Testing Guide: E2E Testing with Playwright and Cypress

Unit tests said everything worked. Integration tests agreed. Then your payment flow broke in production because the date picker component and the checkout API had a timing issue that only manifested in a real browser. E2E tests are the only tests that can catch what no other test can. Key
